    Default Please check my Tune

    My car is a Camaro 2000 A4 it has Cam, heads, headers, Torque converter, LS6 Intake, 3.90 gears, yesterday it ran 11.62 N/A on the 1/4 mile. This is my best time I think is a good time for a DD car.

    But here is the thing, It feel that when the engine starts making power comes the shift 1-2, and then 2-3, and I think I´m wasting that power.

    I´m ussing the WB LC-1 and tune my VE table and I know I need more tuning time to get the LTFT close to zero. Any advise will be very good
    And I need help to adjust the shift points.

    Here are my log and tune.

    TKS for your help

    Your IFR is a straight value across the board.

    You are commanding 11:1 AFR @ WOT. Kind of rich.

    VE values are a lot higher than my cammed ported LS6.

    You didn't log actual AFR to compare to commanded.

    Oh yes Before I start with Efilive, a guy tune my car and made this, what is the correct value for IFR, my injectors are 28.8 lbs/hr.
    AFR 11.1 @ wot is too rich, will be safe to use 12.5.
    On the VE values I´m kind a confuse, that is the result of several tune times on SD. Could that be wrong? I have TB ported, my heads has 305 cfm intake and 260 cfm on ehx.

    Well, what I'm finding is that there's no "correct" value for IFR, but I would go back to the the stock tune values for IFR and the stock VE table + 10% as a starting point. I would probably go to holden crazy & look at one of the stock tunes for your car, compare & start the AutoVE process fresh.

    These are my stock values for my 28.8 injectors.
