multiple fuel pump control over can


Brad Foreman

Recommended Posts

ive finally figured out how to configure the razor but have yet to test in the car

i am running multiple fuel pumps. 2 high pressure pumps and 1 lift pump

i have them wired and configured on the pdm as

hc1 - high pressure pump 1

hc2 - high pressure pump 2

adio 5 and adio 6 bridged for my lift pump

in the ecu i have the fuel pump configured as CAN AUX 1

so in the pdm i select HC1 to CAN AUX 1. but i cant select multiple outputs to be triggered off the same CAN AUX input

 

am i missing something as i want them all to come on at the same time when i prime the engine for start up

 

thanks

Yeah this situation is a bit painful currently, you need a separate function for each pin.  So something like below is how I would do it, 3 GP functions looking at CAN function 1.  There is planned to be a better way to link pins in a future update.
