I wanted to test my E46 M3's electric radiator fan with INPA.
It's a simple enough process.
Run INPA and navigate to the menu option 'Activate'. Choose the radiator fan.
This is where things deviate from the videos and other instructions i have seen.
Once you select the radiator fan you should be asked to input a percentage of full speed, that you would like the fan to run at.
When i activate my fan it just accelerates to a high speed and then decelerates to zero.
I'm pretty sure my version of INPA is one of the last released.
What controls the functionality in these tests?
Is it the contents of an IPO file?
