REVLIMIT ECU file service
Adjusts the engine rev limiter (hard cut) point.
01 How it works
- Upload the original read of your ECU. The system detects the ECU and software (SW) number.
- Select REVLIMIT. 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
REVLIMIT is available as a built-in automatic module for 10 ECU types. You do not need a stored solution: you enter the options you want — for example the rev limit (hard cut) you need — 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 REVLIMIT 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. 454 such solutions have been applied 2,511 times so far.

STAGE1
A safe performance tune that needs no mechanical changes and does not harm the vehicle.
STAGE2
A performance tune that requires hardware changes such as exhaust, filter or DPF removal.
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

Frequently asked questions
What is REVLIMIT?
Adjusts the engine rev limiter (hard cut) point.
Is there an automatic module for REVLIMIT?
Yes. REVLIMIT is available as a built-in automatic module for 10 ECU types (listed on this page). You choose the options you want in the panel and the module builds the change directly in your own file, so no stored solution is needed for those ECUs.
Which vehicles support REVLIMIT?
We have 454 engineer-made REVLIMIT solutions covering 86 ECU types across 15 brand groups. The lists on this page show the brand groups and ECU types with the most solutions.
How do I order REVLIMIT?
Sign in, upload the original read of your ECU, choose REVLIMIT 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.
