Thanks so much! I hope I wasn't coming across as bashing on your program. I have mad respect for your abilities and I know just enough about programming from writing CNC code to be completely confident that eehack is far beyond anything I could accomplish in a hundred years. I'm just super paranoid because in all my years of junkyard scrounging I have only come up with 2 spare ECMs. The stupid cash for clunkers program pretty much led to every one of these cars within 200 miles of me going to the crusher. I will be sure to check all my chassis and engine grounds and make sure the laptop and car battery are fully charged before I try to re-flash. My daily driver is a Cherokee 4.0l so I know what you mean about getting to things when you can on hobbies. My LT1 has been parked since 2015...
