Unrestricted Top Speed
Remove the factory-imposed electronic speed limit, allowing your engine to deliver power to its natural maximum.
Professional removal of the factory-set electronic speed limiter (VMAX). Unlock your vehicle's true top speed potential for track and motorsport use.
Most modern vehicles are electronically limited to a top speed well below their mechanical capability. This is a software restriction imposed by the ECU — not a physical limitation of the engine, transmission, or chassis.
Key benefits
Remove the factory-imposed electronic speed limit, allowing your engine to deliver power to its natural maximum.
German cars (BMW, Audi, Mercedes) at 250 km/h, commercial vehicles at 90 mph, JDM imports at 180 km/h — we remove them all.
Speed limiter removal is often combined with a Stage 1 or Stage 2 remap for maximum performance on track.
No fault codes, no warnings. The limiter is simply raised or removed from the ECU calibration.
How it works
Extract your ECU file via OBD or bench read.
The speed limiter value is raised or disabled in the ECU calibration. Clean, simple modification.
Write the modified file to your ECU. No additional calibration needed.
Your vehicle is now unrestricted. Please use responsibly on appropriate roads or tracks.
FAQ
German manufacturers agreed to a voluntary 250 km/h limit. Japanese manufacturers limit at 180 km/h. Commercial vehicles have legal limits. These are all software restrictions, not hardware limits.
The modification itself is legal in most countries. However, exceeding posted speed limits on public roads is illegal everywhere. This service is intended for track, motorsport, and unrestricted road use (e.g., Autobahn).
Only if your engine has sufficient power. Removing the limiter does not add horsepower — it removes the electronic restriction that prevents the engine from delivering power above a certain speed.
Yes. Speed limiter removal is commonly combined with Stage 1/2 remaps and is included in many of our packages.
