    Default Procharged C-6

    We are having a problem with a Procharged 06 C-6 going lean around 4700. We have 60 lb inj and a kenny bell boost a pump and no mater what we do it wants to lean out.We know the maf is not maxing out and we even told the P.E Table to command 8.00 A/F with no change.


    Please help,Bill

    Hello Bill,

    What boost are you seeing at 4700? What is your Grams/cyl? What software are you using? It's my understanding that Efilive is read only right now, on the E38 computer for the 06 C6's or is it an 05.
    I would rather be Blown, then bottle fed

    If you could post a tun and a log, that would help.

    Hello Bill,

    After a quick look, does raising the Main Ve table at 4700 change the a/f if it does, I would keep going, if not check fuel pressure during the run.
    One othe thing I see which I don't think has bearing on this situtation but the MAF patch hasn't been applied and you are getting close to the max. I would apply this and do a full reflash just for saftey.

    My money is on your fuel pressure taking a dive.
    Whats injector duty cycle? You need to check FP too. Make sure its maintaining 58psi or close to throughout the run.

    Talking

    It Was the VE Table....FP was 58PSI through the entire run. This was our first Blown C-6 so we are still a little under the curve on the new stuff.

    Thanks for all of your help!

    No problem,

    Do you have a dyno sheet you could post? How is the part throttle?
