I recently had an issue with a 0411 pcm I had put in my truck and it would not start at all, I went back weeks later and wrote the tune in the pcm with the write entire option again. it started, I drove it, parked overnight started again and I drove it to work making a few changes for drivability in RTT. I get to work with the changes ive made and write the calibration in the pcm and now it cranks, fires, and stalls very quickly, almost quicker than it would If the VATS were active. I attempted to do another write entire of the file before the changes and still the same outcome. I'm leaning towards a faulty pcm.... but not sure if there may be a software issue or os im trying to run. here is the tune file and the log of the no start. thanks you for any help.
