I hate even asking this question, but it's been so long since I've dealt with one of these older cars and now I have two in my shop!!!!

I have one that I'm tuning, unknown engine (stroker motor? small cam?) ID 1050x injectors with a Procharger D1-SC on it.
I'm trying to load it up on my dyno to get some preliminary numbers before I starting going to town on the VE, and it keeps going into LIMP MODE.

I was hoping someone had some tips to prevent this.

Here is my base file, generic datalog, and screen shot of the DTC's.
22107
22108
22109

Thank you for the help!
The Gen 2's have never given me a headache like this.

I don't see what is causing this...

try disabling the MAP rationality test, try playing with the other rationality tests.

What throttle body is on it?

C6101 and C6102 will need to be raised substantially or maxed out as well.

I figured that out when I saw what Joe wrote
I did max them out

Stock intake and TB. I don't see this OS a lot. It's probably been over a year! So my base file was not up to snuff.

And, of course, I ran into another problem.
These ECU's in these cars don't like to communicate easily
I have to uncheck the High Speed box
And I can complete a full flash!!!

Which means I'm going to have to pull the ECU and it's relocated in the bumper...great!!!
