Race Logic Traction Control
The Spark interface unit allows Racelogic Traction Control to be fitted to a car without electronic fuel
injection. The system can drive up to two separate coils, and interrupts the original signal going to the
coil, and allows the Traction Control system to selectively miss-fire set cylinders.
The unit will automatically cycle the cylinder cut so the plugs do not foul. The more reduction in power
that is requested from the Traction Control unit, the more cylinders are cut. The effect is from a mild
miss-fire, through a soft-cut rev-limit to a total cut.
The spark cut board is a PCB which needs to be fitted into the Traction Control ECU by the engineers at
