I recently took my wife's Chevy SS Back to stock. The car was Heads, Cam, LSA swap. I was able to download a stock tune and use the compare to get a tune loaded. I start the car it runs for a few seconds and dies. These are the only 2 codes I get. I will load a log from start up. Any help would be appreciated. Map sensor is a new GM unit.
Without seeing the tune file, its really hard to tell, i can say that its really odd the injectors dump a massive amount of fuel at initial strt, then literally fall to minimum pulse, at about .8ms! This is likely why its dying, i also notice that cyl. Airmass is crazy high at start up. Im willing to bet that you have something skewed in the airflow models and thats why its not starting
