Fuel Pump Control

[Reedog]

Hi Eric,
I'm considering the ecu-GN and can't seem to find any info on this. Wondering about the fuel pump control feature. Does this mean I can slow down the pump by means of reducing its voltage when fuel demand is low?

Yes, you would need to install a solid state relay to control the pump. Then the ECU will slow the pump down based on manifold pressure (vac/boost).

Eric do you have a diagram/schematic on wiring up the ss relay to ecu? or a link for instructions?
