Hi,
I am having trouble making my fan come on (fast or slow) Evo 9. I do know that the fan control box on the Evo 7/8/9 can go faulty. I can see on the problem solving tab the engine temp rise past the fan trigger temperatures. I have over ride switch wired in so can manually switch on to cool.

Before I dive into changing components could you please check the config settings for the fan set up:

Fan Fast 86
Fan Fast Pin -22
Fan Slow 80
Fan Slow Pin 0
Fans Inhibit 5.03
Fans Inhibit pin switch 9 on

On the ECU documentation for the standard ECU pin outs, the only one listed as fan is pin 18. Do I need to change the fast and slow pin to 18?

Thanks in advance Sean

Good morning,
If you would send a copy of your calibration to tech (dot) support (at) gems.co.uk I will take a look and make suggestions if required. Please just confirm which pins the fan(s) are connected to.
