Do they have to be the same year pcm in order to be compared. Reason I ask is that brian has several files uploaded on his server now and I have downloaded most all of them and when I open them to do a compare all but the 98's look jarbled. Fyi....my cars a 98.

Example.....1st gear shift points that go from like 255mph at 30$% tps to 18 mph 100%. I mean just crazy stuff that car would not be able to run on.

Anyone else encountered this....it may be normal if your not using the correct year file OR someone may have uploaded corrupted files.

 

I've noticed that sometimes the compare feature doesn't work properly like you described. Since I can open the files separately just fine, I manually compare things if I have to.
