M150 GPR PWM Coolant Pump

[Grixa]

Hi.
I have: M150 + PDM15 + Keypad 15 and BMW coolant pump (pwm control).
Its work great. But I need to direct control from keypad button (ON-OFF or 3 different speed).
In M1Tune I didnt see any parameters.
How to do it?

The GP firmware packages don't have another axis for the duty cycle (just Coolant Temperature), but this would be pretty easy to add for a developer.

What firmware package are you using?

I’am using m150 with GPR.
I tried using the aux output, but didn't understand its logic. In my opinion, it is unsuitable.
