GUYS!!! help a brother out. I have made so many mods to my 90-Roc, LB9 that now It won't run right with the factory ECU. I have read so much in the past month about Engine management here in this community that my brain is fried. Dosen't anyone have a simple way to remap and program the OEM ECU?, instead of chuckin out a grand for a Haltech system or gettin a degree in computers in order to understand how to burn chips and so on. I haven't driven my baby in months now and I'm about at my wits end.

Sounds like me a couple years back. Lucky for you your ECU is just fine. Mine was not and I needed to replace with one that DIY-Prom supports.

Two options DIY(best choice) or hire a tuner mail order with you supporting tuner with multiple datalogs.

Read above stickies and ask specific question. Locate a laptop. Build or buy ALDL cable and begin datalogging.
