GReddy e-manage (Piggy-Back Style engine control computer)
When you change air cleaner, exhaust system, intercooler or turbo to racing type bigger capacity ones, you also need to reprogram your original ECU.
Without improving the data of the standard ECU, you cannot expect the best performance of each aftermarket parts and for the worst, you'll damage your engine badly. Racing type intake system allows the engine to suck more air. As a result, fuel setting tends to become lean and causes knocking on the engine. This situation will happen specially when the turbo charged engine gains more boost with the boost controller or bigger turbo. Knocking is an abnormal combustion and causes serious damage on the engines.
GReddy e-manage is the one of the performance engine management systems and this system solves the problem told above. e-manage has excellent functions such as air flow signal control, VTEC control, ignition timing control, fuel injection increase and boost limiter cut, etc.... Specially with the control functions for air flow signal and VTEC cam shifting point, you can adjust them by turning dial knobs on its body.
When you need air fuel setting and ignition timing setting, you can modify your e-manage setting by laptop computer with e-manage Support Tool (Optional special software).
GReddy e-manage is not a full replacement computer, but a sub computer (piggy-back style) and this means even if you sell your car and buy another one in the future, you can still use this e-manage for the next car. And also the price of this new sub computer from GReddy is surprisingly cheaper than any other similar products.
Not only reasonable price, but GReddy e-manage works for most of Japanese sport cars from light modification to heavy one.
