I have a 99 Corvette PCM, OS 12593359 that came in a manual trans Vette. I'd like to run a 4l60e behind this LS1 with this PCM. From what I've read it's possible to load an A/T segment if it's from the same OS. Am I off base or an I do this? If so, does anyone have this segment that I could copy?
Thanks for any help rendered. Bob
I don't believe a 99 Vette A4 file exists with that OS. I just looked at about 20 files I have have and couldn't find one. You're probably going to have to do a write entire with a 99 Vette A4 OS.
Thanks for the info. Considering the work that's been done to this motor, I can then load this calibration into the new file, correct? This is the first time I've tried this so thanks for your patients.
I have access to an 03A4. Could I use that?
Load, no. You could copy the data in the tables to the new OS.Originally Posted by rubrhammer
Lots of differences in a 99 and 03 OS. Is this in a Vette or a swap vehicle?
Going into an 84 square body Chevy.
By 03 they had gone to the 1 Meg PCM so that probably won't work now that I think about it.
03 in a Vette was still a 0411. Planning on using the Vette pedal, TAC and ETC? Not sure if the TAC in 99 and 03 Vettes were the same but if I had to guess I would guess they were. When you say you have a 03 A4? is that the whole PCM or just the file? And guessing the 99 pcm is tuned for the engine mods? Just because a tune is good in a M6 vehicle doesn't mean it is going to be good for a A4 vehicle.

It's my buddies 03. Whole PCM available to copy
Have the pedal TB and TAC.
See the edits I just made to my post.
That's a very good point. I don't tune but can see where there would be differences. Haven't had time to learn how. I do stand alone harnesses and turn off VATS and emissions and do swaps. That really keeps me swamped. I wouldn't have a problem doing the write entire. Going back through to update the tables would test me primarily because I'm not familiar with how many that I'm looking for.
I certainly appreciate your input.
