01 How it works
- Upload the original read of your ECU. The system detects the ECU and software (SW) number.
- Select FAN TEMP. 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
FAN TEMP 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 FAN TEMP 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. 5 such solutions have been applied 6 times so far.

STAGE1
A performance tune that needs no mechanical changes and stays within the factory safety limits.
EGR OFF
Disables the exhaust gas recirculation (EGR) system.
DPF OFF
Deletes the diesel particulate filter (DPF) system in software; if the DPF and AdBlue (SCR) share one housing, AdBlue must be deleted as well.
LAMBDA OFF
Disables the oxygen (lambda) sensors.
VMAX
Removes the speed limiter (Vmax) or sets it to the desired value.
ADBLUE OFF
Disables the AdBlue (SCR) system in software; no AdBlue refills are needed afterwards.
Frequently asked questions
What is FAN TEMP?
Adjusts the coolant temperature threshold at which the radiator fan switches on.
Is there an automatic module for FAN TEMP?
Yes. FAN TEMP is available as a built-in automatic module for 1 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 FAN TEMP?
We have 5 engineer-made FAN TEMP solutions covering 2 ECU types across 2 brand groups. The lists on this page show the brand groups and ECU types with the most solutions.
How do I order FAN TEMP?
Sign in, upload the original read of your ECU, choose FAN TEMP 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.
