hey guys looking to set up a fan control module in my car soon and just want to make sure I understand how to get this all wired up properly. I found this pic on google which makes sense and then when it comes to setting up the controller does this sound right,
when fans are off duty cycle is 100
when fans are fully on it is 0
the middle wire on the 3 pin plug gets wired to a spare aux set as a GP PWM signal and the frequency should be 3.9khz
If I am missing anything p
I use a Mitsubishi fan controller from a Legnum VR-4 on my Link ECU.
The fan controller "fails safe" - if the PWM signal fails (such as with a loose connection), the fan comes on at 100%. The more Duty Cycle, the slower the fan goes - with 100% being fully off.
I am actually running mine at 20Hz, and that seems to actually work OK for me - not sure what impact it would have being driven at a higher frequency?
Here's an example of my PWM output table. As I have a chargecoole
