Hey OGped, I am trying to find the Trubo Kitty base turbo map. I don't see it linked in the video description and I couldn't find one on their website. Could you post the link? I would really appreciate it. Thanks.
I have an mspnp2 94-95 and I notice that the provided basemaps have MUCH less fuel in boost cells than the trubokitty basemap you used here. The diypnp map doesn't pass the sanity check either. lol. Would I be better off using the trubokitty afr and ve tables? I am almost ready for boost and this video was perfect timing. Keep up the great vids!
Interesting, good info for others, thanks for posting. I think you'll be ok with the pnp base map if you take it in stages and also bump up the fuel a little for the first pull. The trubokitty map is extra safe...in most tests I've done it will hit a 10 AFR pretty easily which feels almost like a rev limiter. No power at that point and no danger. I like the AFR table because it's actually a bit leaner than a lot of others...some people target 11.0 immediately in boost and that will not be ideal either.
Hey Ped, installed a mac valve with a switch so I can go between wastegate pressure and the solenoid. Anyway I got it tuned to where I was happy, on a nice 4th gear pull from 2000rpm to redline I would hit my target of 11.8psi at 5000rpm and would fall to 10.7, big improvement over the MBC I had before where it would fall to wastegate pressure (8.7) by redline. So I would say it's dialled for a pull like that but when I'm driving at say 4000rpm and go WOT it will climb along 100% TPS but keep on building boost and hit my boost cut at 13psi but some pulls it will stay at 11.8 at WOT. Why is that? I kind of have it set out like your table in the video, do I have my 80-90% above 2000rpm to high and that's what causing the over boost? My 40%-70% is at 20 above 2000rpm and at 80% - 100% it's at 30 from 3000rpm and at 33 at 7100rpm. Should I be interpolating from maybe 70% 2000rpm up to the 30s at 100%? Would this help with a gradual spool up? On the nice long pull it hits 31% duty cycle at 100% TPS which got me 11.8psi and no more it would drop but on the pull from 4000rpm it is giving up to 13.1 psi?
The ve will not keep going higher as the boost increases it will become a bottle neck based on engine airflow. It will peak at peak torque and then drop as rpm boost climbs.
I agree but in my experience it happens a lot higher than the 12-14 psi I'll be doing on this motor. I've seen the fueling continue to increase up to 25 or more psi which someone def shouldn't be trying on this engine with significant upgrades (forged internals, etc).
@@OGPedXing True , but if you could tune it at al low boost and higher rpm it should still fall off on ve as long as the boost is not Increasing. I have started a megasquirt page on facebook and your welcome to input your knowledge, but is more Buick V6 turbo related content. facebook.com/groups/402465250949856
@@OGPedXing I wonder change the wideband limits in the wideband setup menu ,if it will autotune will not stop if its slughtly too rich. Have you tested that?
Yes I think that's right, it is set to stop autotuning if the current afr hits either the upper or lower limit set up in the wideband config. That's sort of built in but can be removed if you want. You can also add your own custom filter to make it stop autotuning at any AFR you need.
For whatever reason, the default table they use seems too aggressive, it always seems to pull too much fuel when it's hot. So I always up the line as it goes towards the hotter temps.
Hey man, I am just about to finish my turbo build and I can't go see a dyno tuner for almost a month and wanna take the car a couple rips and get it autotuned and tweaked so I can drive it. Do you think I could send you my fuel and spark map and you could tell me if you think they are pretty safe?
Sure I can take a look. On the about page of my channel, there's a button to contact me and it will show my email. You may need to be on a PC browser, I don't think the button shows up in the app. (If I put the email here I'll get spammed by the bots, lol)
Yes the tuning aspect will apply to speedy (speeduino) ecus as well. The menus are a little different (fewer of them for speedy than ms3) but all the concepts are the same.
I’ve got my tables scaled up to 8psi, but it’s running ridiculously lean after changing the tables for boost. Any ideas on where I could start? I’m thinking it’s the VE table being trash.
The rescaling of the tables may have messed it up. I'd street tune at low rpm (3500) and then use that to add fuel to the upper range of the table. You can add a lot above 100 kpa for safety...when you hit that during a pull you will feel it as a loss of power and you can use the logs to dial it back one row at a time.
@@OGPedXing thanks man, I found using the 1.8 turbo base map tables from diyautotune was a great start point for me. Now Ive installed new injectors, and can’t get my idle dialed in (very lean and dies).
From my understanding, no change to VE table is needed as long as the required fuel is set correctly? However changing my VE table at idle helped it run a good AFR. I’ve yet to drive it with the new injectors. I wanna get the idle dialed in first.
@@jacobk9049 yes, if you have newer index injectors, usually only the req fuel change is needed (along with the normal injector setup, dead time, etc config) and the table can stay the same. Older injectors, like rx8 injectors are not quite as plug and play and may need fuel table changes.
Homemade! Not pretty and a first version but it's lasted two years now with no cracking...check out the build here: ruclips.net/video/M39rVlxM5n4/видео.html
Been learning a lot from watching your vids👍🏽👍🏽👍🏽Thanks for sharing🙏🏽
Dang it, that's what I should have asked for Christmas!!! Well, there is always next year :)
Your the goat for teaching us ur knowledge
Appreciate it, my friend. Thanks for watching!
@@OGPedXing also if i blow up my miata i blame u. 🤣🤣🤣
Thank you

Did you re-scale your ignition table to match your new scale on the AFR table - 20 kpa though 205 kpa?

Question for you
How should I set up my mat air density / ideal gas law table
Thanks
For whatever reason, the default table they use seems too aggressive, it always seems to pull too much fuel when it's hot. So I always up the line as it goes towards the hotter temps.
im noticing my fuel table only has round numbers. how are you getting decimals on your table ?
It can depend on the firmware you have. I think some of the megasquirts do that and also speeduino.

does it work with speedyefi ecu?
