Default Stand alone LS1 question.

Alright, I have a 98 LS1 corvette motor that I am putting into a race car. Its basically a C5 shell with C6 body panels. Im not using any of the factory power distribution boxes. I have had the ECM reprogrammed to remove the emissions, vats and other non essential items other than that the tune is stock. The motor will start, run about 15 seconds and die. (Injector pulse is lost) The tuner thinks I may need to run a BCM because Im still using the drive by wire.
Does anyone know if this is the case? Also what will the BCM need to see to make the car run?

Thanks

There are PCMs available for stand alone applications. The systems on a C5 are too integrated, and don't take kindly to you just deleting subsystems and junction boxes.....especially the class 2 serial bus.

Probably help if I knew better what you were trying to do. I'm leaving for my parents in 30 minutes...they live in Highland. I bring my service manuals and DMM with me if you could use a hand.

I'll PM you my number.
