didnt throw any codes , when it runs ,it runs great . the security light is staying on and the low oil light was on ,because my sensor isn't hooked up . i don't understand it .

The only thing i have found to data log is tuner pro RT and it will not connect to my PCM for some reason . Im new to tuning .. this time and next time will be twice for me . I need to trouble shoot why TP isnt connecting , its finding my cable , but not connecting . everything else i use has connected with no issue .

What are your mods? Has the engine ever ran? We need to start from the beginning

Are you talking about the oil pressure sensor or oil level? Security light will be on that is normal with the swap and vats disabled. Like stated above, is this a new build or has the car ran and drove with the current set up before the obd1 swap?

97 trans am
VIN:
WAS TOLD : 9.2:1 compression ratio
CAM duration @ .050: intake 242/exh 248
CAM lift : 600
stock heads
LT4 throttle body and 36lb injectors

Yes i drove the car with the OBD1 2 days ago , it runs great when it runs . you shut it off and it may not restart for 2 days .. Reflash it and it starts right up or stick the OBD2 PCM in it starts right up .

Do you think the pcm is the culprit? If so I'll send you another to try. I did test fire it on my dads camaro but it wouldn't have shown an intermittent issue.

at this point i don't have a clue whats going on . i put the OBD2 back in and its running better than ever , except for the codes .
I did get a MAP sensor fault when i ran it earlier with the OBD1 . i wonder is something is screwy with that . Maybe a short or a bad ground somewhere .. Im lost at this point .

If it was the map sensor it would act up with either pcm. Id feel better knowing it wasn't the pcm at this point
