Really glad you guys are making these tech videos. Are you going to be doing any Ultimate LS setup videos and tech tips? I can see all of the videos are very much relatable to the LS system.
Be sure to check back in! We are about to drop a video just for you!
@@FiTechEFImedia super excited to see that. Thanks

So I’m going through the tech Tuesday videos and learning so much more than what is even mentioned in the installation and instructions. Here is my biggest question, is there a stock setup to reference for a Stock 4.3 Vortec? Mentioning locking out the timing really needs to be more stressed in the instructions.
I just bought mine can't wait to get started
Better get used to being on tech support line. And hot and cold starting issues.
So is loop rate up how fast the idle raises and loop rate down how fast the idle goes down
Somewhere you mentioned that fitech needed to reach the 170 F, then the warming up idle will be operated, how can i reached the warm up idle before factory default temp? I should decrease the number of loop rate down?
Another one, i set the rev limit rpm for 4.3 engine to 4.800 and i sent it to ecu, but after every start it came back to 6600, or i disabled the fan because i don't use external or electronic fan but every time fitech return it to enable.
I need base numbers to start with
What if tps hangs at 1.5 sometimes and sometimes it doesn't but it's starting to do it more often i have looked through your videos and not seen anything about that
So are you guys doing any videos for those of us who have bought the LS kits? Seems like every video is directed at the throttle body versions.
You will actually be seeing one tomorrow on LS Systems, stay tuned!
I messed with both screws front and back and car is idling real high . How can i set both screws back to original settings.
I have kit 70051 , can the system command the IAC shut ? I would like to set the minimum idle speed with the screw on the factory throttle plate with the IAC at zero . Thanks for a reply .
What's the best way to reset back to factory settings i played with both screws fromt and back now the car is idling high.
Check out our video on how the set the IAC steps for how to adjust the throttle.
What do you do for surging between 900 and 1100 all the time cold and warm i got the 1200hp throttle body
Sounds like the loop rate is too high.
This would likely be due to a vacuum leak.
I don’t have all these adjustment settings on my handheld. How do I get them?
You will likely need a software update. Contact our tech department to see if there is an update for you. 951-340-2624 option 2.
I can’t get my ultimate LS system to not idle below 2500 rpm’s and it caught a spark plug wire on fire, what is going on?
Sounds like there’s a vacuum leak. On the bottom of our intakes there are vacuum ports, be sure that they are plugged up if you are not using them.
Been running mine for two years now And has been flawless till today the wife called me and said the truck was running horrible. when she got home it was idling so rich it was stinking up the garage. I checked my bolts on the exhaust near the sensor made sure they were tight. So now what? Runs great till it Idles down then runs very rich.
I got your 92 mm throttle body on my 5.3 how do I adjust for iac
Check out the video on INITIAL SETUP. The second part of the video shows the IAC adjustment. It is done the same on all FiTech systems, just the throttle adjustment screws are in different locations. On the LS its next to the throttle cable cam.
My engine won’t idle. It only runs if I keep my foot on the peddle with the TPS reading 16.0 or more. And when I take my foot off the peddle, the engine immediately dies. How can I resolve this issue?
Having the same issue
Doc.Cali I’ve been on hold with their customer service line for about 10 minutes now. No luck yet.
@@Frankegrenke im 40 minutes in.
@@Frankegrenke so talked to someone just now and really helpful. Went through settings and rebooted. Tried to get to idle with him on the phone. He said could be map sensor getting a poor vacuum reading according to what it is doing and the map reading 96 to 99 while on the gas at 500 to 600 rpm. Im going to see what was sent to my email right now.
Doc.Cali My engine only builds about 3 inches of vacuum (.600 lift cam) but I haven’t been able to find a setting to adjust for that besides the 1-4 cam setting. I may just hook my laptop up to it to see if I can get anywhere that way.
Thinking the loop rate might be part of my hunting idle when I first start. It surges to the point of almost stalling but then recovers, does this till it’s warmed up.
My AFR goes to high 15’s lows 16’s as it’s about the stall before recovering. IAC steps are 3-4 when it’s warm with both fans off. I tried increasing after start fuel and that didn’t seem to help so I set it back to where it was.
Thinking I should try loop rate down. Thoughts??
1200PA system if it helps.
I had similar issue in my stick car, my loop down was 23 & would always goto zero & almost stall when I come to a stop. I lowered loo down to 13 & ita a very noticeable improvement.

Thanks for the reply
I’ll give it a shot and see if it helps
@@ss0073 how did that work out for you?
So confusing. Doesn’t break down loop up and loop down, doesn’t explain what adjusting each value for mentioned does and doesn’t even walk through screen to get through menus. Terrible job.
Loop Rate UP = The IAC uses a PID (actually just PI) closed loop control that adjusts the steps to
achieve the desired idle speed. This value controls how quickly it can open the IAC in response to a
lower RPM, using the “I” (integrator) of the PID.
Loop Rate Down = The IAC uses a PID (actually just PI) closed loop control that adjusts the steps to
achieve the desired idle speed. This value controls how quickly it can close the IAC in response to a
higher RPM, using the “I” (integrator) of the PID.
