VMAX ECU file service
Removes the speed limiter (Vmax) or sets it to the desired value.
01 How it works
- Upload the original read of your ECU. The system detects the ECU and software (SW) number.
- Select VMAX. The file is compared, byte by byte and by SW number, with our stored engineer-made solutions.
- On a match the solution is applied automatically. Jobs without a match go to an engineer. Checksum correction is a separate, optional operation (CHECKSUM) on supported ECUs.
- Download the finished file. The system works 24/7, also at night and on weekends.
02 Written by engineers, tested on a dyno
Every stored VMAX solution is written by our engineers with professional tuning tools — WinOLS, StageX, ECM Titanium and our own Tuning Editor — and the file is tested on a dyno before it is added to the system and sent to customers. When your job matches a stored solution, the system applies it automatically, so what you receive is a solution that an engineer has already written and tested. 922 such solutions have been applied 4,039 times so far.

STAGE1
A performance tune that needs no mechanical changes and stays within the factory safety limits.
STAGE2
A performance tune for vehicles with hardware upgrades such as a downpipe, intercooler or intake; DPF/EGR delete is a separate operation.
STAGE3
A performance tune built from data logs after vehicle-specific hardware upgrades.
LAUNCH CONTROL
Adds a launch control feature that holds the engine at a set rpm for take-off.
POPBANG
Creates exhaust pop & bang / crackle sounds; requires a decatted exhaust with few silencers.
POPBANG SWITCH
Lets you turn the pop & bang feature on or off via a button or mode; may not suit every vehicle.

Which vehicles support VMAX?
We have 922 engineer-made VMAX solutions covering 164 ECU types across 21 brand groups. The lists on this page show the brand groups and ECU types with the most solutions.
How do I order VMAX?
Sign in, upload the original read of your ECU, choose VMAX and download the finished file. Checksum correction is a separate, optional operation (CHECKSUM) on supported ECUs. Where we already have a matching solution the file is processed automatically; other jobs are handled by an engineer.
Are the solutions tested?
Yes. Our engineers write every solution with professional tuning tools and test each file on a dyno before it is added to the system.
