Hi. I bought a 93 K2500 5 speed with a Vortec 5.7, Comp Cam, RV Morse modified TB, and Harris Performance chip last year. Of course, I didn't know much about the engine until I got it home. It ran like crap and it took me a lot of digging to find a semi build thread elsewhere. I turned up the fuel pressure and it started running better, but it still pings under load.
I bought a BURN2, G2X adapter and a couple of chips from Moates but I'm having trouble finding a definition file for my ECM - it's the 1199 (16171199), originally with the BDPF bin. I found the $9A that said it was for 93 5.0/5.7 5 speed trucks, but when I changed the main spark advance table (retarded all cells by 2 degrees), I got more pinging.
Does anybody have any suggestions for this ECM?
Thanks
