WHAT IS A HARD CUT LIMITER?

A Hard Cut Limiter cuts fuel at the set RPM limit. This changes how the engine behaves and changes the sound of the vehicle at the RPM limit. With the manufactures RPM limit, a diesel car will hit the limit and will stay at the exact point until the driver takes his foot off the gas pedal.

The Hard Cut Limiter will cut the fuel injection at a set RPM peak. This will stop the RPM from getting a higher point and will create a popping sound coming from the exhaust. This feature is usually used when the ECU remap is done to change how the engine behaves. The sound of the hard cut can vary depending on the Engine, Turbo and Exhaust. This is best recommended for track and race use with cars without cataylytic convertors or DPF systems.
