The new G4 range of plug-in ECUs are designed to be the most complete plug-in solution yet. There are no adaptor harnesses required nor do you need to make mounting brackets or try and fit differently shaped ECU into the space allowed by the factory. All of this can be achieved because the G4 plug-ins retain the enclosure and mounting brackets of the factory ECU. The OEM circuit board and header plug is removed and replaced with a flexible and easily tuneable G4 unit. Once the installation is completed the upgrade is visually undetectable except for the USB cable which remains for tuning purposes.
In all cases the engine can easily converted to speed density by removing the air flow meter and installing a suitable MAP and air temperature sensor.
All G4 plug-in ECUs come with a base map. While these maps are designed to help save time for you and your tuner, it is essential that these are used simply as a starting point for further tuning.
