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. :bash: 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%.

Yes the Vette is relatively stock. This is the only thing that I thought of last night. I wil try this tonight. Thanks!

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.

Maybe that step can be added to the tutorial for ECT equiped vehicles.

done. It's on it's way to Paul for final review.

For what it's worth, this is the table I use on my 01 and I haven't had any ETC issues even with 232/236 cam and ported LS6 heads. The concept is to keep values low enough at the lower and upper ends to catch a legitimate ETC problem should it occur. These values could stand to be fine tuned, and may need to be modified as required for other engine combinations
