VMAX OFF 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 OFF. If your ECU has a built-in automatic module, you choose the options you want and the module builds the change directly in your file.
- For other ECUs the file is compared, byte by byte and by SW number, with our stored engineer-made solutions and the matching solution is applied. Jobs without a match go to an engineer.
- Download the finished file. The system works 24/7, also at night and on weekends.
02 Automatic module
VMAX OFF is available as a built-in automatic module for 1 ECU types. You do not need a stored solution: you enter the options you want — and the module builds the change directly in your own file, correct for that ECU.
03 Written by engineers, tested on a dyno
Every stored VMAX OFF 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. 846 such solutions have been applied 3,179 times so far.

How do I order VMAX OFF?
Sign in, upload the original read of your ECU, choose VMAX OFF and download the finished file. Checksum correction is a separate, optional operation (CHECKSUM OK) 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.
