Hello there Holley Forums. I have a question of course. I recently installed a Sniper EFI on a carbureted car that I bought. It came with a 750 Holley and an MSD 6AL setup, and it did run. Since I've installed the Sniper EFI, I have to turn off the rev limiter, my problem is the LED light. The LED light on the MSD NEVER goes off making it difficult to program. I put the key in and turn to the on position and the LED lights up and never flashes or goes off. I have searched the forums and I found no answers OR I grossly missed it. ANY help would be greatly appreciated.
