L29 411 swap base file

[Jonw]

Would anyone happen to have a 411 swapped 96 model L29 454 they would be willing to share their base file with, I?m not having much luck getting this thing to fire off after the swap, im not sure I have the correct file for the 4x pickup.
Thanks

You using the l31 van file currently? It should at least start. Just change cylinder volume and injector from black box file. Copy the main ve before you change cylinder volume, then paste it back in after the change (it changes proportionally when you change cylinder volume and you need to change it back).

i in fact did not have the correct file loaded into the pcm. Its running a lot better than it did with the blackbox, but i still have a long way to go to have it dialed.
Thank you for the info
