Doing a motor swap. Got a '05 Vette LS2 replacing a 5.3 Vortec truck motor. Want to keep the RED/BLUE PCM as I need cable-throttle. Got the harness changes made and engine currently starts/idles on the '0411 PCM (using the 5.3 tune). The LS2 motor is bone stock except for headers. Have the Vette MAF on it now but can switch back to the truck one if that makes things easier.

Looked at the stock LS2 tune and was going to copy/paste the tables however ran into a few issues. Current problem is the MAF tables being split on the newer PCMs instead of a single table on the 0411. None of the row headings match and it looks like a lot of number crunching to make it work. Any advice?

Alternatively, can I reflash the '0411 to Vette or F car OS and will those have tables that are closer to the LS2's as a starting point?

Thanks!
