    Default help again

    well i was wrong still no good but had to sort out other problems it seems that painless wiring will only work will 2006/7 comp and has to have the right trans module to com.i had a speed of 255 k at idle.
    found the right service # and installed reflased it to a 6 liter program as it was a 5.3 truck. initial setup to run and was lean +24% LT
    FUEL but ran with a tip in hesitation and with a rolling idle.
    followed swingtans e38 tut and started it up ran good till about 180 deg tried to restart and wont flashes up flares and shut down can keep running for a few secs by pumping throttle the wide band says its 24 to 1 runs with maff connected
    motor is 6.0 liter 224 by 235 at 10 deg fast manifold originally out of a van
    can you guys look at tune and see what im missing i believe i doing the same thing wrong. thanks

    I've said it once and I'll say it again..... A log of the issue would really help out.

    Other than that,
    • The VVE has a HUGE step in it, that's not going to help.
    • The VVE looks to be very rich around idle.
    • Idle speed (after start) control is all over the place.
    • Idle control (max adjustment) is way too low.
    • Min idle airflow is probably too low.


    If you don;t post any log data, it's all going to be guesswork.

    Simon.
