Hardcut Limiter
For All Diesels

A hardcut limiter cuts the fuel at the set RMP limit. This changes how the engine behaves and changes the sound of the vehicle at the RMP limit. With the manufactured RMP 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 RMP peak. This will stop the RMP 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 hardcut can vary depending on the Engine, Turbo and Exhaust.
