HardCut Limiter Diesel is a dedicated utility focused on diesel ECU limiter behavior, including hardcut style rev limiting and launch control related presets. The workflow is based on selecting a supported ECU family profile from an internal list, then applying the appropriate limiter or launch control method as part of a professional calibration process.



The in-app profile lists shown in the screenshots include multiple OEM diesel controllers used across VAG, BMW, PSA, Ford, Opel Vauxhall, Land Rover, Honda, Mercedes, Fiat, Kia, Hyundai, Renault, Dacia, Suzuki, Alfa Romeo, and Lancia platforms. Availability varies by ECU hardware, software number, and calibration strategy.
