Link G4X ECUs do not require the use of an air flow meter. The engine can be converted to speed density using a MAP sensor and an intake air temperature (IAT) sensor (IAT sensors sold separately)
If you are wanting more boost than the OEM 2 bar map sensor, We can provide a 3 or 4 Bar sensor at extra cost.
The G4X Subaru WRX & STI V7-9 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.
We can also provide the following with your new Link ECU at an added cost: - Fuel System Upgrades - Turbosmart Wastegates, Blow off valves and Fuel Pressure Regulators - Boost Control Solenoids - Dyno Tuning - Engine sensors and plugs etc - Full Link ECU engine wiring installation available at an extra cost
