Our M4 ECU is capable of controlling up to 4 High Flow Injectors in sequential mode. It is the perfect match for a Motorcycle, Honda, Toyota or Mazda 2 Rotor Rotary. Like all of our ECU's, it is capable of controlling fuel and ignition on normally aspirated, turbo, or supercharged and nitrous oxide assisted engines. In a semi-sequential mode, up to 12 cylinders can be controlled using the M4 making it the perfect swap for injected marine engines such as Mercruiser and OMC. This ECU can be enabled to allow data logging and Wideband Lambda Control
