I can see this has been asked before, but I'm wondering if I can have specific help with what I'm after.
Hardwire PDM 25, Blink Marine Keypad, Emtron ECU
Can I have electric water pump PWM control (via coolant temp) AND a keypad button to make the pump run at 100%? For bleeding the cooling system when the car's off.
From what I've seen, switching the output to ON only references its current value on the PWM table. Is that right?
The alternative is controlling the pump via an ECU table, outputting a % via CAN for the PDM to reference, and having an axis on that table as the CAN keypad override button with all of the values set to 100%. The problem with this is I'll need the ECU to be on to do it. I was hoping for a PDM-only solution.
