Looking for tune file for LT1 1996 conversion to LS PCM

The X/Y isn't the same as the '0411 but this might help you extrapolate.

do you by chance have the 1996 impala ss tune that you could share? thanks

Been a little bit, I wasn't getting notifications that this thread was being replied to but wanted to say thank you all for the help. Since I started this post I actually found an 02 Express van in the junkyard and grabbed the PCM. Turned out to be a 156 OS which is a common one and I could read it with tunerpro. This one was a factory 350/4L80e tune, and I did a segment swap to make an M6 tune using an 02 z28 file for the transmission side. I still have to update the injector data, thank you for that help! I will be running the stock 96 LT1 injectors since the engine is stock. With the mention that the LT1 uses the MAP sensor for spark tables, should I fail the MAF and just run in SD mode, or better to keep the MAF? I do not have a 96 timing table to look at, but I do have a 95 LT1 tune to reference that I can copy over to the van tune. Because I will be using the 4x crank wheel it will be running in batch fire mode, no more sequential.
