Discussion and questions related to the course Motorsport Wiring Fundamentals
I am i right in thinking that the 12v supply to my injectors should come form the ECU and the 12v supply to the COPs should come from the PDM so it can shutdown separately as part of the Master/kill switch operation?
ECU is liferacing, PDM is AIM PDM32
The ECU doesn't supply 12V to the injectors, it provides the ground source for the injectors. i would supply both the coils and injectors from the PDM.
I was worried that if there is a variance in the voltage that it would effect the operation of the injectors
That's why you use the same voltage source for the injectors and coils so that the ECU can adjust the dwell and dead times to suit.
OK copy. Thanks very much... It is obvious to me now...
