    I have a dumb question if this is allowed. Is it suggested/recommended to run this process with STFT only?

    Feels like I am in tuning hells BTW. LOL. I should have just dropped a bone stock motor in. :(
  3. Jerking when vehicle is at rolling idle.

    Tuning has progressed a bit but now I have hit a nasty snag. Current tuner does not seem to be able to crack this one.

    In the last weeks I was convinced, begrudgingly, to remove some of the aftermarket components from my vehicle.

    I did some tuning with pat G and none of the files he sent me really made anything better and then I did some tuning with lsx power tuning. did the live session and after about an hour or so it...

    OK but that doesn't solve the problem. Anyone can make a comment like that.

    If it helps sure.
  9. RPMs coming down too fast and stalls. Car does not respond to changes?

    Hired a tuner. He has changed the desired air flow, TC, TF many times over the course of an hour and we cant get the engine to stop stalling after a blip of the throttle.

    I actually have new knock sensors and harness! Yay for me! I finished up the engine rebuild about 3 months ago and it was a total refresh aside from breaking into the short block.

    I tried pulling spark advance till the engine ran like a snail and the knock never went away.

    My guesses are that it is mostly all fake knock due to the engine or burst knock shows up as KR as...

    :UPDATED:


    I think I finally graduated with a C- from the school of hard knocks today. The truck ran pretty good with minimal dipping of the idle or surging ( solved with the desired airflow and...

    I would say that I could see .98 to 1.14 BEN in some cells while others are tighter.


    One thing I noticed is the AFR will be great for awhile. 14.8. Then I get into traffic for 20+ minutes and...

    Well my bike got a flat (and I didn't die!!) so I have been forced into working on this yet again. Reporting in that results are much better with the new (correct) injector data. Practically no...

    Statesman,

    I wanted to let you know that you were right about the injector data. I started looking at it and it didnt make sense. At one point in time I was talking to a tuner (didn't end up...

    Seems drastic to just fix the hunting idle issue that remains at this point. BUT I am willing to try it. You guys know your s$#it. :)

    I am still blown away that I didn't know the difference between 1 trip and 2 trip. :wallbash: Maybe I should go back to riding my sport bike. haha.

    Oh man! It looks like I am using an out of date document for the VE tuning process.

    I wasn't sure if a custom OS was out for this truck. That might help.

    I've played around with it so much in the last weeks it is hard to know what all has and has not been done.

    Well junk. It seems that the fix is still partial. Some PIDs can be logged through pass through mode and other cause it to have the same error as above.

    You know what is weird?
    Things will be running great and then every once in awhile the truck just takes a dump. Can't ever figure out why. Then I will walk into a store and come back. Truck runs...

    I have been doing a lot of work on this and making some progress.

    The truck doesn't stall as much anymore. Only sometimes randomly and multiple times in a row. It used to stall going into R and...
