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!

Does anyone know where i can find wiring schematic's for 1998 and 2002 fuel sending units. I am having no luck on the web finding them.

Here ya go.
Cheers,

Post 10 maybe what they are referring to:

I found the link to that topic in here:

I google searched the forum using:

0411 ecu 97-98 site:www.corvetteforum.com

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

thank you. I cut the wire at pin "A" on the right sending unit and that was it... works great now.

:cool: More forced induction guys have done the ECU swap. If you need more help you may try starting a topic in the Forced Induction section. :cheers:
