PWM Input.

I'm slowly working my way through setting up my PDM.

I have one stumbling block at present. My ECU (Emerald K6+) is capable of controlling my water/meth system using a 2D lookup table (using boost and revs). This outputs a PWM low sided signal.

I could use a Solid State Relay to control the water/meth injection but would rather use the PDM. Can I use a PDM input to read the PWM signal and then use this to switch an output to my water/meth injection? The PWM Input is 'only' an on/off signal so I'm guessing this would be OK but, as the water/meth system needs to be 100% reliable, I'd rather make sure this is right! Thanks. Wyn.
