Using PDM to control fuel pump output

[alexmas0n]

Hi, I have a fuel pump that I control with the pdm now just using a digital input from my stock ECU. i havea fuel pressure reading being sent by my dash to the CAN bus which i read on the pdm. I was wondering if I could set up a rule that would cycle at a fast enough rate to have the pump target a specific fuel pressure and maintain it, thus keeping the pump working less,

The PDM only operates at 50Hz which is not fast enough to PWM a fuel pump.
