Hello.

I want to control an electronic water pump (EWP) using PWM control with an EMUBlack and a PMU-16.

I believe I need to configure the PWM output settings on the EMUBlack and the channel settings on the PMU.

Is this configuration correct?

Is it okay to set the EMUBlack’s PWM output to “none”? Or do I need to select a CAN bus or something else?

I think I need to select a DC channel as the control channel for the PMU-16, but is c\_ecu\_pwm1DC correct?

I use EMU Black, PMU-16, ADU-5, GPStoCANV2, USBtoCAN, and these all items are connected through CAN-Bus.

EWP is Davies Craig EWP80.
