1998 0411 swap fuel gauge is not working

[kylenautique]

Hi everyone!

I just finished up my 0411 swap on my 98 K1500. Everything is perfect, except for the fuel gauge. Its pegged beyond full. Does anyone have any data on how to calibrate this correctly? I have EFI Live.

Here's some photos of what's in the tune currently

Is the easiest way to make the fuel gauge work, to just install a 96-97 fuel sender, 96-97 gauge cluster, and bypass the ECM? Go straight to the gauge cluster?

First thing, what operating system are you running? If you use the wrong one it may not have the PWM driver enabled on the ecu.

These are the correct setting, adjust fuel tank size to match what you have. I use HP Tuners, but you should have these tables in your program, they might be called something different.

96-97 still use a pwm driver from the computer to run the fuel gauge. You can't run it "straight to the cluster"

Dude thank you so much! That was the issue. I had to run the tune through Tunercats to enable the PWM fuel gauge. EFI Live didn't support that for some reason. Its working now. This website is the best!
