I am looking for some advice on fuel pump wiring. I am setting up a car with a surge tank and would like to run at least the main pump from surge tank to engine on a PWM output as it is just a fast street car and am wanting to run a 1000hp capable fuel pump without overheating fuel through excessive pumping. The vehicle was originally carbed so is a bit of a blank canvas. Have been thinking about just using one output from the ecu and running Two speed controllers, one supplying each pump and running off the same PWM ECU signal. Would there be any issues with doing this?

From what I understand It did run an ecu and took the engine speed signal from the diesel pump. I guess the best way would be just to trace the wires, feed it a signal from the link and see what happens. Failing that I will look at mounting an aftermarket Tacho in the dash.

Vehicle is a LJ78 Landcruiser. All up and running with no issues and I am wanting to wire an output to run the factory Tacho. I bought vehicle with the 1UZ engine conversion done running a factory 1uz ECU and have rewired with Link Tacho has never been hooked up or worked, I believe the tacho may have originally used an RPM signal from the Diesel ECU Just wondering if anyone has any experience doing this?

I am running a 1uzfe non VVTI using the factory distributors and igniters. I am using a modified 1uz VVTI base map configured to run the twin spark From what I understand the dwell is controlled in the igniters Am I best to just set the to something the same across the board or will it make little difference?
