A buddy's car, running the fast computer with a crank trigger and msd cam sensor. All this is routed through the fast edis box. He can only get the number 3 and 6 coils to fire( using the ls1 coils 8 of them) The hole where the opti was is welded and the sensor is located close to the top of the hole where the opti was. Everytime the motor rolls over the sensor lines up. Cant figure out whats up. Anyone ever done this?
