Just turn off the btm and copy a timing table from a newer Vette / Camaro. If you need a tune file to look at I have a couple.

I can't say I've looked at a 99' file but I'm willing to take a look if you would like. Most of the gas stuff I've looked at has been in HPTuner but I would be curious what they look like in EFILive.

Send them if you would. I used to use tuefiledepot but they got banned. This is quite different from the e54 ecm but i feel like its simpler than im making it out to be

I guess I didn't realize what an L31 was
Did they not change over when the half tons did?
