FuelTech’s SparkPRO-4 is a high-energy inductive ignition module designed to be used with ignition coils without an igniter (dumb coils). The SparkPRO-4 has 4 ignition outputs, each output may be connected to only one coil at a time, and is available in versions from 1 to 8 ignition outputs. It has a high voltage of up to 430V at the coil’s primary. SparkPRO ignition modules are compatible with any programmable ECU that has dwell control but cannot be used with a stock ECU.
