What does the system do?
A rev limiter restricts further engine acceleration at a defined threshold. Its intervention can be progressive or abrupt, depending on the ECU strategy.
Additional options explained
Hardcut – Rev-limiter behaviour
A hard limiter intervention differs from exhaust crackles when lifting off the accelerator.

Function, changes and requirements
What does the option mean?
Hardcut concerns that intervention characteristic. Sound alone demonstrates no additional power and does not define an agreed rev limit.
What do we check on your vehicle?
We check engine and transmission limits. The researched Popcorn supplier scope specifies manual gearboxes; this is no automatic-transmission approval. The exact control unit, software version, fitted hardware and intended use determine the scope. A configurator entry does not replace this assessment.
Frequently asked questions
Does every vehicle support this function?
No. We check the vehicle, control unit and software against the actual supported function. Include existing faults and modifications. Transmission functions also require the exact gearbox version.
Does selecting an option approve its use?
No. Changes to emissions, noise or protection functions can affect legal use and operating safety. This page promises no road approval; diagnosis and a permissible repair are considered first.
