amg Posted September 6, 2017 Report Share Posted September 6, 2017 I have an intercooler pump with built in controller that requires a PWM signal to wake up and control the speed. The pump is not designed to run at 100% duty cycle all the time, otherwise I would just join the signal and power wire together and leave the ECU out of it.As I'm at the early stages of configuring the Thunder, I don't want to complicate the setup by introducing conditions upon which the speed will change (i.e. IAT or coolant temp) and only want the pump to start up and spin at say 75% duty cycle. I may do the conditional speed later or decide to change the duty cycle to 50% (or more), depending on my findings when the car runs.What would be the easiest way to implement this? I.e. start up and setting the duty cycle via PWM.Thanks. Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted September 6, 2017 Report Share Posted September 6, 2017 I know that this doesn't answer your question, but the greater water flow through a closed loop water 2 air circuit the quicker air ambient air cools the water down. Use a 2D PWM table with rpm on the axis. 500rpm @ 75%DC. Set condition 1 only with rpm greater than 500rpm amg 1 Quote Link to comment Share on other sites More sharing options...
amg Posted September 25, 2017 Author Report Share Posted September 25, 2017 Turns out I've been using wrong Aux outputs which don't support GP Output and GP PWM. Figured it out now, thanks again. Quote Link to comment Share on other sites More sharing options...
