The 4-Channel Ignition/Injection Driver Board can be used for any engine with 1 to 4 cylinders in full sequential mode with one injector and coil per driver, and with 6 and 8 cylinder engines in semi sequential mode and wasted spark with 2 injectors per driver and one coil per driver. The MS case is used as a heat sink for the IGBTs.

The kit comes with injector drivers, the igniton driver can be ordered separate.
