If the application has less than 4 injectors using any pin connected to the proper channel will work. + ### Coils Current versions of the Speeduino use low-power output signals, designed to work with external small-signal ignition coil drivers, whether a separate type (module or ICM, igniter, IGBT, etc.), or built into the coil assembly ('smart' coils). This method permits Speeduino to have great flexibility to control most types of ignition systems. Attaching the Speeduino outputs directly to a traditional high current passive ("dumb" or 2-pin) ignition coil without an ignition coil driver WILL cause damage to your Arduino.
