spoolxr6 Member 312 Member For: 14y 3m 26d Posted 12/12/10 07:10 AM Share Posted 12/12/10 07:10 AM The factory ECU grounds the FP relay and the pump is either on or off, how do you vary the voltage to the pump? This could only be done if the +ve feed to the fuel pump relay was running through a voltage regulator/or a current limiting device and monitored/altered via closed loop by the ECU. Can the falcons do this? Link to comment Share on other sites More sharing options...

Have pull the fuse for 1 of the 2 pumps and the second 1 when reactivated make it about 30% lounder. Link to comment Share on other sites More sharing options...
