L67 conversion... Fuel Pump PWM speed control

[ev351]

Hi all, Im looking for info how the VS supercharged V6 Fuel Pump Speed Control is operated. I want to regualte the speed of my pump using the factory speed control, but i cannot find any wiring diagrams for it? it does not seem to be shown on the ECU diagram, maybe i just cant see it?? Or is it controlled by the BCM?

Cheers..

there is option flag to turn it off and on, then scalars to change the flow or duty cycle. ill have a look and update the vs L67 xdf

ok ive updated the VS L67 xdf added the pump scalars.

Oh cool, that was way more than i was expecting... Im stuck on something a little more simple than that Like does the PCM control the pump speed control directly or does it run through the BCM? Im just having trouble finding the wring for the controller that normally sits in the rear of the car....

The PCM sends a PWM signal to the fuel pump speed control module.

oh tops, I saw some of the modules on ebay, so i will grab one, and hopefully i will be able to work it out... I will check the PCM wiring diagram again, I guess i have missed the pin.
