Hi guys, I have a 1999 C1500 5.0 vortec 3.42 geared automatic truck I have swapped to a 5.7 vortec. I just got my EFI Live V2 and have scanned my stock 1999 vortec 5.0 vcm and would like to see someone's 1999 C1500 5.7 vortec auto bin file to compare please? I have a 1998 bin for a 5.7 auto truck but EFI live won't let me directly compare the files since they are different OS's (the 1999 is ecm 09360595).

Thanks!

Steven

GM didn't build a C1500 with the 5.0L in 99 in the US, is this truck somewhere abroad? Which ECM does it have in it? If it is a van it could have the 0411 ECM which is completely differrent from what the trucks got.

They definitely built it, look it up on rockauto.com. 1999 C1500 5.0. The engine code is CMUJ. It's a carry over of the old body style. I own a very original condition example of it. And no this is not abroad.
