1998 to 2002 ecm conversion help
Okay I have converted the ecm in my 1998 to a 2002 ecm with only one problem, the fuel gauge. With the setting for the 1998 fuel system the gauge reads dead empty with a full tank. when I change all fuel system settings to 2002 the gauge works but only reads 3\4 full with a full tank.where do i need to look to get the gauge to work right with the 2002 ecm? I'm tuning with HP tuners.

Okay a tuner in my area told me i need to cut a wire on the secondary tank sending unit but didn't remember which one. has anyone on here done the this before?

Before I started cutting wires I'd try to find a schematic for both and I would find the voltage values each computer is looking for to present to the gauge. Bill Curley would be my go to guy if I were you. Good luck and Merry Christmas!

It has been done and there are topics out there, digging it up may require getting creative with Google.
