This ECU is designed for ignition only control.  It can run distributor or distributorless engines up to 4 cylinders; its possible inputs are crank speed & throttle angle.  It can be used with ignition against speed or if a throttle position sensor is fitted to the carburettors, it can be programmed to change the ignition according to the open of the butterflies. It uses USB communication from your laptop, which is then converted by a small piece of hardware (MBE985) that converts the USB in CAN, which is a more stable system, used by car manufacturers worldwide.
