What does the system do?
An ECU may restrict vehicle speed by limiting torque. This is separate from the engine rev limiter and the speed the vehicle can physically achieve.

Function, changes and requirements
What does the option mean?
This option adjusts a supported stored speed limit. It adds no engine power and guarantees no higher actual maximum speed.
What do we check on your vehicle?
Tyres, brakes, chassis, driveline, approval and intended use must suit the proposed target. 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.
