Love your videos. So many tuners gate keep info and when i ask tune related questions in groups, i usually just get comments saying "take it to this tuner" etc... thank you for teaching rather than gate keeping
Thanks! Just rebuilt a 5.3 Gen 4 because of a wiped cam. Installed a TOW cam from summit and yes it cam with specs. Just starting to tune it. This has helped a lot.
For anyone trying this method: If you have an early LS PCM with a secondary VE table, disabling the MAF will trigger the secondary VE table. Changing the primary table will do nothing for you. Took me a while to figure that one out.

I have the mvpi 2 ordered and waiting to get here, I’ve been watching a bunch of your videos and they’re great man! Keep it up and it’s been helping me out a ton already just messing with the samples and learning the system before I even attempt to touch it on my truck
Have been tuning for about a week and HOLY CRAP it is overwhelming. I started this journey because I love learning a new skill and tackling problems myself. Having fun but man its a SHARP learning curve.
You rock bro. I thought I was a good tuner holy s*** period seriously man you're amazing at tuning and I've learned a lot from you and I appreciate it. I'm tuning a 4.7 l V8 biturbo Mercedes 4matic CLS550.. what a pain in the ass it is.. I put 3 gallons of E85 in it today mixed with 9 gallons of unleaded 93. So immediately my O2 sensors went bad s*** crazy I had minus 25 and plus 25 on the other. long-term going one way short-term going the other but that f****** thing ran awesome . I have to obviously trim the map if I was going to keep it but I'm going to save the tune so next time I'll have an E30 tune saved so I can just flash it next time I want to add some ethanol. Got to get a ethanol reader for sure. These goddamn pumpgas e85s in South Florida are so fluctuating as far as ethanol content on a daily basis. It could be 20% off one day got to get one of those sensors. I have one from zentronics.. I don't know yet. Trying to get the most boost safely out of this thing
sounds terrible. I never do any mix without a sensor as the wot fueling can be so incredibly different depending on the blend you wind up with. cheers m8
I have my PE set to 55% throttle, and 0 delay. I think I just about got my knock issue worked out. Colder plugs helped, opened up my air box and unfortunately pulled some timing.
Hi Kyle! A little late to the game here, but finding your content very informative. I just dropped in a 5.3L with DoD delete cam from Summit into an 07.5 Silverado WT 4x4 that previously had a 4.8L. At some point next year, I plan to obtain a wideband and hopefully your services for both my trucks (other is 2018 GMC Sierra 5.3). In the mean time, the motor is getting "broke in" after the rebuild and driven around a little. With that said, I did use a base file from an 07.5 with a 5.3L. But, I am having some hot start issues. Cold start and idle is fine (I did raise it a touch to 680 from stock). I just have to give it a little gas to start it when it's at operating temp. What first steps do you recommend without the wideband to dial in a very base tune for cold/hot startup, idle and normal driving? Would the method described in this video work? Or would you suggest a different route? If you happen to see this, thank you for your videos, hard work on the production, and for answering my question. Cheers!
When using the factory o2 sensors to tune i am also using the maf right?? So do not disable the maf? Only disable the maf if im going speed density which would be tuning with a wideband???
How is my histogram supposed to log LTFT when we shut it off to run MAF only I drove with the tune and it logged nothing but zeros on the MAF ERROR graph we made
I have an rcsb 2003 silverado 4.8/manual trans with long tube headers into true duals with no catalytic converters....CAI....ported throttle body and e-fan conversion ....ive removed all my torque management and raised my rev and speed limiters...and that alone has made a noticeable improvement but I believe there is more power to be gained from VE, power enrichment, and timing adjustments....but I'm a newbie to hptuners and do not have a fraction of the knowledge you posses....ive had hptuners for about two years and I've experimented by making changes based on comparing repository tunes from vehicles with similar mods as mine ....but that's not even remotely effective....ive learned some things from doing it that way but probably not any good things lol....but over the last two years of "winging it" and trial and error...ive at least managed to not melt a piston, bend a valve or pop a motor....but that's probably just dumb luck.....how much would you charge to make me a new tune and email it to me....i can email you a couple data logs and a copy of my current tune if this is something you would be interested in doing.
Greeting, trying to tune (for my first time) a 2012 gmc 1500 with truck norris cam and headers. I followed this video and got all the setting set the same way you do, but when i do my driving to fill in the table, its only filling out the top line, nothing else. Did i forget to switch something on or off for mine to fill out more than the top row of the ltft table?
When you paste the graph from the long term graph we made do you have calculate it to the VE table ? Or can you just multiple by percent half? And leave it there
i ordered thr aem wide o2sener..and gaugekit..mpvi2prolink.....have not installed the 02sen yet..2004gto5.7ls1t56manual longtubeheaders. N/A....i have the 4 stock o2s now dose the... new wideband o2sen..replace one of my factory 4 o2senser on the car ..or will there be 5 o2sensers on the car now.. or do i remove one of the factory o2s and put the wide band in one of my factory spots??? and thank for all iv learned already ur realy good at it ...
It is mentioned that there is no need to adjust power enrichment settings, however my current tune (done by a performance shop after installing BTR S2 Truck Cam) has the delay at 0 and throttle position at 60. Should I bump them up to stock settings or to what is showing on this vid?
Thanks to your videos I've been able to begin tuning the engine swap I did on my 05 vette, went from LS2 to 408 stroker with heads / cam so quite a big change. It starts up cold perfectly, still fighting the warm starts a bit and currently just doing MAF tuning. One thing I noticed is the commanded fuel at idle isn't Lambda 1 like it was, it's now on the rich side and is commanding 0.996 (or there around). Any idea what might be causing this?
.996 is what it commandeds when you have the decimal resolution out that far. It's still 1.0 effectively. If it runs good cold but has issues warm check your ECT tables.
@@GoatRopeGarage Thanks! I'll take another look at the ECT tables. That's something I did make some changes to initially. I currently have to stab the throttle a tad when warm and it fires right up which made me think I should be making more adjustments to the Idle Startup Airflow than I already have. I just went out to log but unfortunately I'm having a vacuum leak from the MAP sensor lol. I tried to retro fit my LS2 map on the LS3 intake after realizing I can't set the LS3 map to the -0.31 offset on the E40.
@@isidrosevier1125 yeah, there are a lot of things that effect idle airflow, find an issue the other day where a table used oil temp for an idle adjustment.
I’ve been watching your videos on tuning, very easy to follow and I’ve found them really interesting, although it’s now got me thinking about the remap on my car?👍 I’ve just had my car Dynod and remapped. The Dyno graph shows torque and BHP gains across the whole curve. It’s a N/A Porsche 997 3.8s. I had gains of 20hp and 20lbs/feet torque. Which is about standard for this N/A car after a remap. It was on a mustang 4 wheel Dyno. I got it dynod as I made a number of mods and I wanted to make sure the car was ok, ironically 😂 A few things I’ve noticed since the tune which worry me, or not? Stock the MAF was reading 5.0 g/s at idle. I fitted a larger throttle body and it dropped to 4.5 g/s. When I had the car remapped it was reading 5.75g/s. As I fitted a 82mm throttle body the shop said it had to be calibrated as the standard is 74mm throttle body would read wrong? Is this true? And would I expect a change in MAF reading after a throttle body change? I have no fault codes. Does the recalibrated MAF cause a different reading to standard? The car idles very smoothly at 800 rpm. Before the remap it idled at 700 rpm. Is this normal after a remap? I have more pops when decelerating than before? Normal? I have a performance exhaust fitted. I think so? Now here’s the bit which did make me start looking. In a 5th gear full run the Lambda sensor started around 1 and started to drop as the car accelerated to around .8 , maybe slightly lower. This is probably ok? In the final pull of the day in 4th gear the lambda sensor read 1.3/1.4 which is high across the graph. I didn’t realise this until I got home. I’ve got to say the car is running ok, pulls really hard after 3000rpm which is what the Dyno shows. How do I tell from the limited information I have if I have a bad remap? Can the car run lean in a 4th gear pull and Richer in a 5th gear pull? Will my long term full trims show if the car is running ok at lower RPM but has a fuelling issue at higher RPM? Does the long term fuel trim take an average across the whole table and take all ranges into account. I have a tool which can read quite a-lot data, I’m not experienced in this but I find it really interesting stuff and if possible using my fuel trim data see if my car I’d running right? Or can I use the short trim data and record it on a full load pull and see what the fuel trim does? Any advice?
So stupid question…once you tune the maf does one leave the settings to keep it always running in maf, or does one have to also do the ve table and change the settings back to normal?
G8 LS3 480 Tuned using ltft and noticed when in MAf tuning mode it ran great. Did three rounds of MAF tuning and wow. Then did VE tuning and strugged to stay running and did not feel great or wow at all even after f3 rounds of VE tuning using just on board o2 and ltft. Then when I put it all back to normal after tuning the both of them still not wow like it was when tuning MAF. Any ideas ?
Kyle, on a 2013 Escalade looking to dial in MAF and speed density/VE with LTFT, I can't see how to force MAF or speed density as you show. I don't even have dynamic airflow tab, MAF fail setpoints, or DFCO setpoints. Could you show this type tuning with the limited options on a truck like mine? Thanks!
What is the over all timing can you put in a 98 Silverado l31 with factory distributor I have lt4 hot cam in it and aluminum heads 202 160. Roller rockers headers bored out and other things to but I'm at 34 total timing and it's a dog at bottom end can I put more timing in it
If you're getting rid of dod just focus on the first one unless you have one of those oddball cars with the manifold switch then you'll need to do the last one too.
I have been flooding trying to put new iac and tps , maf to but had po codes on maf, and I’m flooding bad when keying on ain’t got no rear o2 so how do I tune them out and why is my Silverado 02 flooding at prime. Thanks for your help if you can
Kyle , I had an idea the other day as i’m running catless , instead of creating a new port with the blunge for the wideband in the headers can i replace the rear o2 sensor with the wideband sensor just for the Convenience. Or will this give me an inaccurate reading ?
Need it in front of the cats, better off pulling a front while you tune then putting the stock back in. You're on a mustang aren't you? Make sure you don't have factory widebands
@@GoatRopeGarage I have dual exaust and x pipe half way back. also noticed the ltft is not the same for both banks . where is the best place to install a wide band or do I need 2 wide bands one for each side. ? LS3 in the G8 moving slow in dallas.
When I do my MAF tuning and copy over the data from scanner it just makes the car run worse and no power and pops. I am doing copy-paste-multiply by half. I am running a wideband too. Please help!!!!!!
I got the wideband kit with the air/fuel guage and what looks like an O2 sensor. Having trouble trying to figure where to connect it even with the directions. Can you help please? Have an L33 5.3 in a 2006 silverado.
I got the hp tuner mpvi2 with the AEM air/fuel ratio kit with it. With the gauge and O2 sensor looking thing that goes into the exhaust pipe. With 8 credits so I can get into my ecm unlimited times for 6 and have 2 for my 03 Denali too. That has the LQ4 6.0 that I will build all the way and put I to my truck later when my woman gets her new truck. Gonna grab her 4L80E with it.
So on a stock gen 3 LQ4, would it be possible to use the ltft to tune right up to WOT since power enrichment is disabled from factory? As long as a guy hasn't messed around with the spark timing.
I tried this however I was unable to log the map sensor. I only got results in the 10 kpa column and it wouldn't let me add it to the channels. 2011 camaro ss
There is an option on the scanner under Vehicle called "Repoll for Supported Parameters", try that and then see if you can add manifold absolute pressure to your list. That's what your VE table is based on for sure if it's a 2011.
On my gen III LS with hp tuners I have the option under special features to command closed loop on or off. Is there any reason I can't just use that function to force closed or open loop for tuning?
@@GoatRopeGarage Thank you!!! That feature saved my ass the other day when one of my 02 sensor took a shit and read dead lean while I was test driving.
This video made we wonder, I've got exhaust leaks and I do believe that is why my aem wideband is reading lean, but is it also because I only have the wideband in one bank of the V8's exhaust
Hey I wanted to ask you I have your GRG scanner layout and for some reason it only logs on the first row is there something I'm missing or a channel I should have?
I have a ford ecoboost that is randomly commanding stoich at wot in 4th gear around 5200 rpms. Power enrichment is commanding 0.75 in that range. Nobody seems to be able to help me.
Injector duty cycle is 30%, frp is 2900psi, 0 knock, 20psi of boost, advanced at wot is 12 degrees, 87% throttle. Ltft is adding 25% without methanol and ltft is trimming out 25% when spraying methanol. Short term stays 10 +/- in wot. Recently I've seen at part throttle the ltft start hitting +25 without meth. definitely worried.
Ive requested the throttle to open 87% but the factory tune only request 45%. Ive replaced the entire fuel system. Including injectors, hpfp, upper and lower fuel pressure sensors. Lpfp dc is 35% and seems to be fine. I barely understand the speed density part of the tables, im not sure if im allowing to much air flow or what. My fuel system and this turbo im running (gtx2867r gen 2 .64ar) should have enough fuel for atleast 24psi without the methanol.
Not a bad idea, it's it ramping it is it just jumping to stoich? If it's jumping you've got to have something that is causing it to drop out for some reason. Use your logs and work back to the cause, if you're trending everything that can effect PE you should be able to see what is taking control and throwing things off
Hi Kyle, Thanks for these great videos. I know this is perhaps not the right forum to ask technical questions but im really stuck here. My wideband is backordered, I've put in new Cam and Heads on an LS1, took it to a 'professional' and it works great WOT!! I've got a large area in the 1500 2000 range which knocks. I'm looking at my LT + ST and they dont seem really off . Its -1 , 0's and an occasional 1. Help please. what beyond adjusting the VE table could be contributing to knock in this range. The Advance commaded is 23 or so degrees. Retard is pulling 5 to 7 degrees out in the 1500 to 2000 RPM range about 30% throttle. Any pointers on where i could be going wrong here. I've followed the basic process outlined. Shut off Maf, Adjust VE with LTFT adjustments (.5 percent pastes) , then move on to the MAF.. but i havent even got to the move on to MAF Stage.. ive got this nasty midrange knock. Could you help me get pointed in the right direction please.
Any chance you could a vid helping us Jeep 4.0L JTEC guys? There is almost no info out there. I can tell its a simple tune but ive just got nothing to go off. You definitely are VERY knowledgeable with tuning and HP tuners and the Jeep world could REALLY use your help! A simple vid with basics like setting up AFR Histogram, injector scaling, fueling & timing advice etc...? PLEASE HELP
So I did everything you said in the video to tune with the maf sensor but I'm only getting values to populate in the first column under the 1500. Mine starts at 1500. Do you know why that is???
@@amber-leighehrhart3440 Double check the parameters that make up the X and Y of your graph and make sure you're logging them. ruclips.net/video/f3txG2I8InQ/видео.html
Which is better to.tune for an mpg tune stft ltft vs wide band And if I am tuning for best mpg what tables to tune beside maf +ve. what to eneble +what to disable
As long as it's mostly stock, tuning with the fuel trims is fine for mpg. If you are looking for power or have mods like a cam swap, then you are better off with a wideband. I just tuned my truck that way while waiting for my wideband in the mail. Stock 2011 Silverado that was averaging 15.6 mpg combined. After my tune it looks like it's going to average about 17.5-17.8. I'll know for sure after getting some more miles on it. I also disabled DOD and adjusted the PE. That was it..... Basically the same as you get from a mail order tune.
My Ltft are at 15% what can I do to get them down? And I've not disable my power enrichment but when I went in HP tuners to check it it's at 0. I did send out pcm to have vats delete and emissions delete. What should it be at? I'm am new at this tuning and your patron for the help is full. Need to get my trims down.
Im just starting to try to tune over here. Setting up data logging for ve tables on a 4.2 vortec 6 cyl. Can i ask if i should raise my pe rpm/tps for logging purposes? Do i need to patreon for that? If so which level? My pe rpm vs tps is like 30% where your example is 85%. Not sure how effective logging can be if its going to go into PE over 30% throttle
unplug them. it will throw codes. in the EDITOR, under "Engine Diagnostics" (the little yellow motor at the top) find the code(s) it threw, and select in the drop-down "no error reported".... you can now throw your CATS and downstream (rear) o2 sensors in the trash and never see that code again. *for off road use only*
i have an issue i cant seem to find the answer i have a truck that the LTFT are showing rich 5-7% rich but my wideband is showing leaning. like 15.8-16.2 AFR when i’m tuning the VE table but when i turn the MAF on it’s showing 7-12% rich on LTFT but in my wideband it shows 14.7-15.3 AFR. not sure what’s wrong there...
@@gmtuning454 what does your wideband show when you have the LTFTs on? If everything is functioning correctly your LTFT's should correct to 1.0 lambda plus or minus one percent and your Wideband should show that. Might need to let it idle for a couple of minutes to let your long terms learn.
So this is basically tuning for only cruising around with best fuel economy not for really tuning full throttle performance whether your using maf or sd
Dude the videos are very helpful, I am going to order the AEM wideband sensor on payday, Put a cam in, and deleted DOD, Trying to get it running safely to bring to the exhaust shop. I have one issue though when I check my MAF with this or any of your other videos something just isn't right, when you look at it in the scanner the MAF is not in sync with RPM's 3400 RPM, and above populating while at idle. Any idea what's up. its a 2007 Yukon XL Vin 3
@@GoatRopeGarage When you say wide band use serial. Do you mean That the wide band will give serial data and I can use that to go to the laptop and not the MPVi2 then set up the MPVi2 to read that data? I think that is what I am gathering. I have no problem ordering the aem30 - 0300 right now but was not sure if It would work without the proset features and prolink cable.
Man my traction control and stabilitrack disable and I get harsh shifts from 1-2 when running the time for dialing it all in with fuel trims, any idea?
I am wondering I have a Gen 4 4.8 L and the fuel trims seem to be cutting into my ability to idle and run it will cut and trim so much that the truck will die
So we're assuming the O2's are swinging nice like they'll do with stock exhaust manifolds. If you've installed headers and moved the o2s 2ft+ downstream, how do you keep them from being lazy and thus potentially causing inaccurate trims? I know you can buy o2s with better heaters, but is there a way in the tune to get the o2s swinging better with long tube headers also? This is why I continue to use a wideband, but i still get lean idle from heat soaked iat's in my early gen3 pcm.
You can adjust your crossover voltage, so get the thing warned up and reading as close to 1 on your wideband and then see what your narrowband sensors are reading and adjust the millivolts according to that. Then put it back in closed loop and watch your LTFTs versus your wideband, of it starts to drift you need to adjust again.
Hey I messaged you Saturday about having trouble starting in sd mode. Sunday set everything back to stock and redone everything starts fine in sd mode now. I think I had the vve table messed up bad cause after starting over I was bad rich adjusted table it's good now starting. Now I've start doing the vve tuning again but doing it with ltft instead of wideband. I think I've got the histograph set wrong. Do you know how to setup the histograph using mpvi 2 standard and the aem 30-0334 can bus guage kit. I want to adjust using wideband. One way I set it up it dont populate any cells and other way I did it it does but dont know if is right. The way I set it up is 100 * ([50119.238] - [50118.238]) / [50118.238]. The 50119 is what my wb shows in hpturners. It just dont appear to look right on graph one will be 6.54 and right below it was like 20.something. and on ltft the same cells show 1.95 and 2.60 in them

I have an rcsb 2003 silverado 4.8/manual trans with long tube headers into true duals with no catalytic converters....CAI....ported throttle body and e-fan conversion ....ive removed all my torque management and raised my rev and speed limiters...and that alone has made a noticeable improvement but I believe there is more power to be gained from VE, power enrichment, and timing adjustments....but I'm a newbie to hptuners and do not have a fraction of the knowledge you posses....ive had hptuners for about two years and I've experimented by making changes based on comparing repository tunes from vehicles with similar mods as mine ....but that's not even remotely effective....ive learned some things from doing it that way but probably not any good things lol....but over the last two years of "winging it" and trial and error...ive at least managed to not melt a piston, bend a valve or pop a motor....but that's probably just dumb luck.....how much would you charge to make me a new tune and email it to me....i can email you a couple data logs and a copy of my current tune if this is something you would be interested in doing.
What about using the STFT + LTFT math parameter in HPtuners ? Is using LTFT only more accurate ?
How do you do this WITH a wideband. Cant find any info on it
Do these numbers on Ltft table completely transfer over to the ve tables?
I know it’s a stupid question but after I’m done tuning do enable the things we disabled
F*** yeah wideband all the way
Greeting, trying to tune (for my first time) a 2012 gmc 1500 with truck norris cam and headers. I followed this video and got all the setting set the same way you do, but when i do my driving to fill in the table, its only filling out the top line, nothing else. Did i forget to switch something on or off for mine to fill out more than the top row of the ltft table?
When you paste the graph from the long term graph we made do you have calculate it to the VE table ? Or can you just multiple by percent half? And leave it there
where would i start to tune my lifted 2002 Suburban ? I have searched for help on tuning a lifted truck and havent found anything.
i ordered thr aem wide o2sener..and gaugekit..mpvi2prolink.....have not installed the 02sen yet..2004gto5.7ls1t56manual longtubeheaders. N/A....i have the 4 stock o2s now dose the... new wideband o2sen..replace one of my factory 4 o2senser on the car ..or will there be 5 o2sensers on the car now.. or do i remove one of the factory o2s and put the wide band in one of my factory spots??? and thank for all iv learned already ur realy good at it ...
It is mentioned that there is no need to adjust power enrichment settings, however my current tune (done by a performance shop after installing BTR S2 Truck Cam) has the delay at 0 and throttle position at 60. Should I bump them up to stock settings or to what is showing on this vid?
Thanks to your videos I've been able to begin tuning the engine swap I did on my 05 vette, went from LS2 to 408 stroker with heads / cam so quite a big change. It starts up cold perfectly, still fighting the warm starts a bit and currently just doing MAF tuning. One thing I noticed is the commanded fuel at idle isn't Lambda 1 like it was, it's now on the rich side and is commanding 0.996 (or there around). Any idea what might be causing this?
.996 is what it commandeds when you have the decimal resolution out that far. It's still 1.0 effectively. If it runs good cold but has issues warm check your ECT tables.
@@GoatRopeGarage Thanks! I'll take another look at the ECT tables. That's something I did make some changes to initially. I currently have to stab the throttle a tad when warm and it fires right up which made me think I should be making more adjustments to the Idle Startup Airflow than I already have. I just went out to log but unfortunately I'm having a vacuum leak from the MAP sensor lol. I tried to retro fit my LS2 map on the LS3 intake after realizing I can't set the LS3 map to the -0.31 offset on the E40.
@@GoatRopeGarage mine has a problem similar to this but I think itm ight be more IAT related, but could ECT also
@@isidrosevier1125 yeah, there are a lot of things that effect idle airflow, find an issue the other day where a table used oil temp for an idle adjustment.
@@GoatRopeGarage wow that's crazy
Hey man some ecu dont support or show cylinder missfires on HP, im logging every cylinder on my 1999 ecu and nothing shows up??
I’ve been watching your videos on tuning, very easy to follow and I’ve found them really interesting, although it’s now got me thinking about the remap on my car?👍 I’ve just had my car Dynod and remapped. The Dyno graph shows torque and BHP gains across the whole curve. It’s a N/A Porsche 997 3.8s. I had gains of 20hp and 20lbs/feet torque. Which is about standard for this N/A car after a remap. It was on a mustang 4 wheel Dyno. I got it dynod as I made a number of mods and I wanted to make sure the car was ok, ironically 😂
A few things I’ve noticed since the tune which worry me, or not?
Stock the MAF was reading 5.0 g/s at idle. I fitted a larger throttle body and it dropped to 4.5 g/s. When I had the car remapped it was reading 5.75g/s. As I fitted a 82mm throttle body the shop said it had to be calibrated as the standard is 74mm throttle body would read wrong? Is this true? And would I expect a change in MAF reading after a throttle body change? I have no fault codes. Does the recalibrated MAF cause a different reading to standard?
The car idles very smoothly at 800 rpm. Before the remap it idled at 700 rpm. Is this normal after a remap?
I have more pops when decelerating than before? Normal? I have a performance exhaust fitted. I think so?
Now here’s the bit which did make me start looking.
In a 5th gear full run the Lambda sensor started around 1 and started to drop as the car accelerated to around .8 , maybe slightly lower. This is probably ok?
In the final pull of the day in 4th gear the lambda sensor read 1.3/1.4 which is high across the graph. I didn’t realise this until I got home.
I’ve got to say the car is running ok, pulls really hard after 3000rpm which is what the Dyno shows. How do I tell from the limited information I have if I have a bad remap? Can the car run lean in a 4th gear pull and Richer in a 5th gear pull? Will my long term full trims show if the car is running ok at lower RPM but has a fuelling issue at higher RPM? Does the long term fuel trim take an average across the whole table and take all ranges into account.
I have a tool which can read quite a-lot data, I’m not experienced in this but I find it really interesting stuff and if possible using my fuel trim data see if my car I’d running right? Or can I use the short trim data and record it on a full load pull and see what the fuel trim does?
Any advice?
So stupid question…once you tune the maf does one leave the settings to keep it always running in maf, or does one have to also do the ve table and change the settings back to normal?
yes
good stuff. just subscribed!
I got an original dyno jet wideband commander. Is there anything wrong with using that wideband?
Ha! First again. LOL On a serious note though, can you make the window with HPT larger? It seems to cut portions of the tables off.
G8 LS3 480 Tuned using ltft and noticed when in MAf tuning mode it ran great. Did three rounds of MAF tuning and wow. Then did VE tuning and strugged to stay running and did not feel great or wow at all even after f3 rounds of VE tuning using just on board o2 and ltft. Then when I put it all back to normal after tuning the both of them still not wow like it was when tuning MAF. Any ideas ?
Kyle, on a 2013 Escalade looking to dial in MAF and speed density/VE with LTFT, I can't see how to force MAF or speed density as you show. I don't even have dynamic airflow tab, MAF fail setpoints, or DFCO setpoints. Could you show this type tuning with the limited options on a truck like mine? Thanks!
on your editor, go to Edit> View> Advanced and you should get more options... MAF is in the Engine Diag
So when you finish the maf and the speed density do you reinable the maf and dynamic airflow?
Yep
@@GoatRopeGarage What about DFCO?
As long as you were adjusting idle and partial throttle only, wouldn't PE never kick in in the first place?
I shouldn't say adjusting, but logging idle and partial throttle only.
Correct
You still do the patron offer?
What is the over all timing can you put in a 98 Silverado l31 with factory distributor I have lt4 hot cam in it and aluminum heads 202 160. Roller rockers headers bored out and other things to but I'm at 34 total timing and it's a dog at bottom end can I put more timing in it
Should we clear LTFTs in vehicle controls and special functions before doing the first log?
Yes
Ok soo by following your steps
ive disabled Speed Density and Maf
Left O2 sensors On
The right way is to just turn one off not both?
Speed Desity uses Ve Table.
On the e38 ecm which table do you focus on when doing virtual VE tuning? If I'm deleting DOD should I just cope and make them all match?
If you're getting rid of dod just focus on the first one unless you have one of those oddball cars with the manifold switch then you'll need to do the last one too.
@@GoatRopeGarage perfect thank you I appreciate it
I have been flooding trying to put new iac and tps , maf to but had po codes on maf, and I’m flooding bad when keying on ain’t got no rear o2 so how do I tune them out and why is my Silverado 02 flooding at prime. Thanks for your help if you can
How do I tune a vehicle without a ve table such as a gen 1 ls 2001 gmc. thanks
Kyle , I had an idea the other day as i’m running catless , instead of creating a new port with the blunge for the wideband in the headers can i replace the rear o2 sensor with the wideband sensor just for the Convenience. Or will this give me an inaccurate reading ?
Need it in front of the cats, better off pulling a front while you tune then putting the stock back in. You're on a mustang aren't you? Make sure you don't have factory widebands
Goat Rope Garage i play around with multiple cars but here im talking about a dodge , i have removed the cats already from the car

I got the wideband kit with the air/fuel guage and what looks like an O2 sensor. Having trouble trying to figure where to connect it even with the directions. Can you help please? Have an L33 5.3 in a 2006 silverado.

With 8 credits so I can get into my ecm unlimited times for 6 and have 2 for my 03 Denali too. That has the LQ4 6.0 that I will build all the way and put I to my truck later when my woman gets her new truck. Gonna grab her 4L80E with it.
So on a stock gen 3 LQ4, would it be possible to use the ltft to tune right up to WOT since power enrichment is disabled from factory? As long as a guy hasn't messed around with the spark timing.
Should
I tried this however I was unable to log the map sensor. I only got results in the 10 kpa column and it wouldn't let me add it to the channels. 2011 camaro ss
There is an option on the scanner under Vehicle called "Repoll for Supported Parameters", try that and then see if you can add manifold absolute pressure to your list. That's what your VE table is based on for sure if it's a 2011.
Thanks I'll give it a try
So for MAF tuning we disable dynamic air but in speed density we enable it?
Disable the MAF on speed density
On my gen III LS with hp tuners I have the option under special features to command closed loop on or off. Is there any reason I can't just use that function to force closed or open loop for tuning?
Yep, your can do it that way, just have to remember to turn it off before your start logging
@@GoatRopeGarage Thank you!!! That feature saved my ass the other day when one of my 02 sensor took a shit and read dead lean while I was test driving.
This video made we wonder, I've got exhaust leaks and I do believe that is why my aem wideband is reading lean, but is it also because I only have the wideband in one bank of the V8's exhaust
Hey I wanted to ask you I have your GRG scanner layout and for some reason it only logs on the first row is there something I'm missing or a channel I should have?
Yeah, you are missing the rows channel
I have a ford ecoboost that is randomly commanding stoich at wot in 4th gear around 5200 rpms. Power enrichment is commanding 0.75 in that range. Nobody seems to be able to help me.
Injector duty cycle is 30%, frp is 2900psi, 0 knock, 20psi of boost, advanced at wot is 12 degrees, 87% throttle. Ltft is adding 25% without methanol and ltft is trimming out 25% when spraying methanol. Short term stays 10 +/- in wot. Recently I've seen at part throttle the ltft start hitting +25 without meth. definitely worried.
Ive requested the throttle to open 87% but the factory tune only request 45%. Ive replaced the entire fuel system. Including injectors, hpfp, upper and lower fuel pressure sensors. Lpfp dc is 35% and seems to be fine. I barely understand the speed density part of the tables, im not sure if im allowing to much air flow or what. My fuel system and this turbo im running (gtx2867r gen 2 .64ar) should have enough fuel for atleast 24psi without the methanol.
Should I request only 45% throttle angle and work my way up depending on fuel?
Not a bad idea, it's it ramping it is it just jumping to stoich? If it's jumping you've got to have something that is causing it to drop out for some reason. Use your logs and work back to the cause, if you're trending everything that can effect PE you should be able to see what is taking control and throwing things off
@@GoatRopeGarage ramping to stoich. 0.75 to 0.79 to 0.81 to 0.93 to 1.00
Hi Kyle, Thanks for these great videos. I know this is perhaps not the right forum to ask technical questions but im really stuck here. My wideband is backordered, I've put in new Cam and Heads on an LS1, took it to a 'professional' and it works great WOT!! I've got a large area in the 1500 2000 range which knocks. I'm looking at my LT + ST and they dont seem really off . Its -1 , 0's and an occasional 1. Help please. what beyond adjusting the VE table could be contributing to knock in this range. The Advance commaded is 23 or so degrees. Retard is pulling 5 to 7 degrees out in the 1500 to 2000 RPM range about 30% throttle. Any pointers on where i could be going wrong here. I've followed the basic process outlined. Shut off Maf, Adjust VE with LTFT adjustments (.5 percent pastes) , then move on to the MAF.. but i havent even got to the move on to MAF Stage.. ive got this nasty midrange knock. Could you help me get pointed in the right direction please.

Which is better to.tune for an mpg tune stft ltft vs wide band
And if I am tuning for best mpg what tables to tune beside maf +ve.
what to eneble +what to disable
As long as it's mostly stock, tuning with the fuel trims is fine for mpg. If you are looking for power or have mods like a cam swap, then you are better off with a wideband.
I just tuned my truck that way while waiting for my wideband in the mail. Stock 2011 Silverado that was averaging 15.6 mpg combined. After my tune it looks like it's going to average about 17.5-17.8. I'll know for sure after getting some more miles on it. I also disabled DOD and adjusted the PE. That was it..... Basically the same as you get from a mail order tune.
My Ltft are at 15% what can I do to get them down? And I've not disable my power enrichment but when I went in HP tuners to check it it's at 0. I did send out pcm to have vats delete and emissions delete. What should it be at? I'm am new at this tuning and your patron for the help is full. Need to get my trims down.

@@GoatRopeGarage rpm
Im just starting to try to tune over here. Setting up data logging for ve tables on a 4.2 vortec 6 cyl. Can i ask if i should raise my pe rpm/tps for logging purposes? Do i need to patreon for that? If so which level? My pe rpm vs tps is like 30% where your example is 85%. Not sure how effective logging can be if its going to go into PE over 30% throttle
i set mine up between 85 to 90 tps percent
Commanded afr or eq reflects pe so as long as you're using a wideband it is fine
With a forced induction setup , do you typically keep the stock front 02 sensors in the system or just use a wideband?
I'll keep the front ones, you'll still want to be able to run closed loop it can help with changes in weather, altitude, etc.
I have a question when I'm tuning my efi do I leave the rear O2 sensors on or do I shut then off which is best
unplug them. it will throw codes. in the EDITOR, under "Engine Diagnostics" (the little yellow motor at the top) find the code(s) it threw, and select in the drop-down "no error reported"....
you can now throw your CATS and downstream (rear) o2 sensors in the trash and never see that code again.

Missing a parameter, track your graph back to the math and make sure you don't have any pink blocks, those indicate parameters you're missing
I am wondering I have a Gen 4 4.8 L and the fuel trims seem to be cutting into my ability to idle and run it will cut and trim so much that the truck will die
You have headers?
So we're assuming the O2's are swinging nice like they'll do with stock exhaust manifolds. If you've installed headers and moved the o2s 2ft+ downstream, how do you keep them from being lazy and thus potentially causing inaccurate trims? I know you can buy o2s with better heaters, but is there a way in the tune to get the o2s swinging better with long tube headers also? This is why I continue to use a wideband, but i still get lean idle from heat soaked iat's in my early gen3 pcm.
You can adjust your crossover voltage, so get the thing warned up and reading as close to 1 on your wideband and then see what your narrowband sensors are reading and adjust the millivolts according to that. Then put it back in closed loop and watch your LTFTs versus your wideband, of it starts to drift you need to adjust again.
Hey I messaged you Saturday about having trouble starting in sd mode. Sunday set everything back to stock and redone everything starts fine in sd mode now. I think I had the vve table messed up bad cause after starting over I was bad rich adjusted table it's good now starting.
