Does anyone have experience setting up a Fuel pump utilizing a PWM output? Haltech Elite 2500 using a Fuelab in tank power module.

Elite configuration is set at 1000HZ (MFG says 500 to 1500), ECU outputs are set to Active State (LOW), Drive Type (BOTH). I can only get pump to operate between 80-100% duty cycle. I have talked to Fuelab and have the pump wired correctly however they have no guidance on the ECU setup,

I have attached the Instructions lets see if someone has a different interpretation.

I haven't had anything to do with installing one of these pumps so i can't speak from experience. It seems like you're on the right track with the 1000 Hz output and I can't see why that wouldn't work. The only other consideration may be the requirement for a pull up resistor to 12V on the output.
