Ro55ifumi Posted March 3 Report Share Posted March 3 Hello, I'm new to link and installing my G4X onto my R32 Skyline GTR and I am having trouble with the fuel pump control settings. The OEM setup uses a FPCM (fuel pump control module) that I have previously bypassed, but still use the ground signal to trigger my relays. I'm running a lift pump to surge tank to main pump setup. What keeps happening is the pump stays on constantly when IGN is on. The default plugin setup is 3 speed relay control. Which I assume should work since I'm using that signal to trigger my relays. It does not. I tried STD mode and no go. Anyone else run into this before? I know it's common to bypass the FPCM on the R32 as it's prone to failure.

Vaughan Posted March 3 Report Share Posted March 3 How exactly have you wired all of it? Also note that Aux 1 & 2 in your basemap are working in the opposite direction, change their active state settings to low if you want them to ground the output when active.

Ro55ifumi Posted March 3 Author Report Share Posted March 3 I figured it out. Since it's bypassed, I had to switch to standard relay output and also had to switch the pump relay to Aux 2 instead of Aux 6. Active state was also switched to low as well. The way my pump is wired is I only use the blk/yel signal from the OEM harness to trigger my 2 relays which get direct 12v power.
