I'm working on a trans am, I just did a turbo build on it. Just swapped it over to 2bar and went for the first start. It starts and immediately dies, if you give it throttle it does not rev. I've gone through everything I can think of and nothing has helped.

fuel pressure 58 steady
everything plugged up
added lots to VE, took lots away, nothing changed

MAF fail high-0
po101-mil on first error
maf table-0'd
VATS turned off


any idea guys? It might be from 24hr thrash sessions on this but i'm lost on what the problem is at this time

Some OS's are slower to flag the MAF code and move into SD. Try setting the 0Hz cell in the MAF table to like, 12g. That should let it run and start for the instant that it needs in order to set the MAF fail code and get you running off of VE.

I'm looking and i'm not sure what table you are talking about, you are right it wont set the code

Open the calibration; Click on Engine>Airflow>MAF Calibration [button]

On the left the horizontal axis is labeled "Airflow"; right click and choose Units, G/sec. The bottom cell in the MAF table is 1,500 HZ if I remember correct (sorry, when I said zero above, I really meant the far left cell). In that call alone, put 12.5 into the field.

When you start the car with no MAF, for an instant, it will use that cell, and that cell will let the car crank right up and code.

Make sure to set P0101, 0102, and 0103 to ALL be 0-MIL on FIRST error. I see you mention 0101, but the other two need to be set the same. You can un-check the SES-enable for all of those errors.
