The Nissan Skyline GTR Fuel pump speed controller requires two Auxiliary Outputs from the ECU to control fuel pump speed.

 

Auxiliary Output 1 = FP Control Module 2

Auxiliary Output 2 = FP Control Module 1

Set Aux 1 & 2 Active States to High

 

 

 

Example Fuel Pump Speed Control Setup:

 

Enter the following settings into PCLink in the Fuel Pump Control section.

Speed Control Method = Three Speed Relay Control

Fuel Pump Relay Output = Aux 6

Fuel Pump Speed Relay 1 Output = Aux 2

Aux 2 Active State = High

Fuel Pump Speed Relay 2 Output = Aux 1

Aux 1 Active State = High

Prime Time = 3.0 s

Low -> Med RPM = 1500 RPM

Low -> Med Duty Cycle = 10 %FF

Med -> High RPM = 2500 RPM

Med -> High Duty Cycle = 22 %FF

 

Using the above settings would control the fuel pump speed as follows:

 

 

Note: The both Aux 1 & 2 will be High during prime meaning full pump speed.

 

To confirm fuel pump speed is working correctly measure the voltage at the fuel pump.

 

Battery voltage = Full Speed

Three quarter battery voltage = Medium Speed

Half battery voltage = Low Speed
