EcuTek Releases Phase 2 RaceRom !!

The Nissan 370 doesn't have a fuel pump controller like the Subaru or like the GTR... so there's no duty to log or change.

The pump is ON or OFF.. that's done with a relay that's controlled by the ecu.

Even if you have a car with a pump controller like subaru or gtr, logging fuel pump duty isn't very useful using OEM hardware. It's really only used to make sure the fuel pump isn't overrunning the fuel pressure regulator at idle.

We found this out when we started wiring fuel pressure sensors to the ecu to monitor fuel pressure on bigger powered setups.. we found hardwire 485s was causing major fuel pressure creep at idle! I ended up making a plug and play hardwire kit that allow you to keep variable ecu control pump speed with all the advantages of going direct to battery power

On brush-less fuel pumps we can make the speed of the pump very variable using certain pump controllers + custom ecutek code.
