Well if thats the case why do you have regulated return listed as an option under fuel system selection in your notes for the xdf?


Also, yes there is a "voltage control" on all 98's


Uses a 2 speed system that halves system voltage at the pump through a resistor. PCM triggers a relay based on RPM and that shorts the resistor and jumps voltage to 12v+


You even had the option to control the trigger RPM in earlier craj0 tunes man.

not sure what your referring to exactly about regulated return but the scalar pid is not strategy specific. Ford reuses the same code. For example the VCT_SW exists but the ecu is not capable of controlling variable cam timing.

Thats not a voltage control thats a 2spd relay control its a simple on/off output to that relay.

The pump output voltage table has no affect though so setting it to 0 volts or 12 volts isnt going to change anything.

Ok.



Is there anyway for me to set the trigger to like 100rpms?

You cant use the 2 spd fuel relay with the on3 pump. AFAIK they are not variable speed.

Cutting the power to the pump will likely burn it up and fuel pressure wont be consistent.

Im aware.


I will continue to use your old tune with the 2 speed pump trigger accesible I guess.

is there any reason I just cant delete the dropping resistor from the pump circuit?

see 3 posts up ^^

you cant use the resistor with a non variable speed pump
