Vmax Off - Speed Limiter Removal
Removes the electronic top-speed limiter so the car can reach the speed its powertrain allows.
Many cars, and German brands in particular, leave the factory with an electronic top-speed limit written into the ECU software, often set at 250 km/h or 210 km/h. This is a software cap rather than any mechanical limit on the powertrain.
Vmax Off removes or raises that cap so the car can reach the speed its engine, gearing and aerodynamics actually allow. Only the speed limiter is touched; ABS, ESP, the airbags and the other safety systems remain fully active.
At the ECU level the change edits the limiter value in the speed-governing map, so nothing else in the calibration is affected. The solution is prepared for your exact ECU and can be returned to stock at any time.
It is intended for track and derestricted-road use. Any high-speed running must always match the road, tyre and traffic conditions and comply with local traffic law, so it should only be used where doing so is legal and safe.

Frequently Asked Questions
What does Vmax Off do?
It removes or raises the electronic top-speed limiter in the ECU so the car can reach the speed its engine and gearing allow.
Who is Vmax Off for?
Track-day and motorsport use, and markets where the factory 250 km/h (or similar) limiter is not required. Tyres, brakes and suspension must be rated for the higher speed.
Which file do I need to upload?
A full read of the original ECU file. On some cars the limiter is in the gearbox or body module; we tell you after analysis.
How long does Vmax Off take?
Minutes if it is in the database, otherwise typically 10-45 minutes.
Is Vmax Off reversible?
Yes, by flashing the original file back.
Is it safe to remove the speed limiter?
Only when the car's tyres, brakes and cooling are suitable for sustained high speed. Removal is intended for closed-circuit use; public-road speed limits still apply.
