Ecm for supercharged, Faulty FMU damaged engine
I may have asked this question as a reply to a post by accident. (first try) Sorry if I confused anyone. My LT4 with a procharger was damaged, I believe, by the two FMUs sent to me by ATI that were defective. Has anyone else had such a problem. secondly, what ECM can be used to run, & tune my 86 L98 with boost without a FMU? What ECM/chip was used on the Callaway twin turbo? thanks

I decided on the 7749 ecm.(syclone) It is still easy to come by, and it is cheap. I also have everything I need to burn chips already. The 7749 can also work with low Z injectors(big ones).
The aftermarket FMU's are nice, but so is the price. There are also hacks for some of the other common corvette ECM's. Good luck!
