So I got my launch control working by fixing the clutch switch wiring... but sometimes when im using it and i let off the gas the car will shut off and if i try to start it up it will just keep cranking. If i power cycle it everything goes back to normal and it fires right up... pretty weird. I'm using the launch pin and fuel cut (ive tried spark cut and spark + fuel cut they both do the same stalling thing).

 

Seems to work fine now... weird
