    Link G4X ECUs do not require the use of an air flow meter. The engine can be converted to speed density using a 3 Bar MAP sensor and an intake air temperature (IAT) sensor (Both sensors sold separately)

    The G4X Mazda RX7 Series 6 plug-in ECU comes with a non-engine-specific base map. The ECU will need to be configured for the engine type and then tuned by a professional. The ECU comes with free PCLink software.
