EDIS8 Wasted Spark FAST XFI 2.0 Sequential Fuel Injection

F.A.S.T. is not know to be really user friendly because of software updates. I used to deal with a F.A.S.T. rep who helped many racers with their systems at he track. I've lost contact with them as I went back to NA for my bracket car. I can build & tune many carbs for what it costs to install & tune an aftermarket FI system.
