    Question AutoVE tuning 2004 Corvette... Help

    I am having trouble making the car run in SD mode. I got the IAT hooked-up and the three MAF wires disconnected. When using the AutoVE.tun (written per the tutorial instruction) The car just dies right after I start it. I have tried stopping the PCM from running the MAF tests and it still happens. I also went out on a limb and disable abuse management thinking maybe it had a part in it.

    I wish it was a diesel. I know how to tune those in any case.

    Any input is appreciated.

    Stock or Custom OS?

    If a COS 3/5 check the A0008 table is say 1.00. This is a multiplier to the B3647 (Open Loop) table.

    Is the Vette relatively stock? If it's just a bolt on car, start with a stock VE table and try multiplying by 10% rather than 15%.

    I would try the 10% to err on the safe side, but if you still feel like it's running too rich, you can go with 5%

    When I switched my relatively stock 01 to SD mode, I had to crank up the VE table a bunch. If all else fails, PM me your e-mail address and I'll send you the tun file I used. You'll have to do a copy and paste or manually input the values but once you make the change, the car should run fine. It's interesting that the VE table that I optimized when running Mass Air is nowhere close to the one I wound up with for running SD.

    ETC predicted airflow was the problem. I added 40% and had no issues.
