Fuel Level Sensor on 08' Vette

[2008ProchargedLs3]

Hello, I have a 2008 C6 and just installed a Racetronix 525lph fuel pump module. These require you to either switch you oem fuel level sending unit over to the new module or you can reverse the values with tuning software.
So once was 3/4 full is now reading 1/4 full. Can anyone point me in the right direction on what needs changed in HP Tuners to correct this. Pump was already installed with this option in mind.

Thanks

I would start here. Try reversing the values for one table at a time.

Reviving this thread in hopes of making my 2006 Corvette have functioning gauges again. The 05-06 sending units are discontinued and I was only able to get 08+ fuel pump and passenger side transfer pump (Delphi ft4031, which included 08+ sending unit)

I am told GM switched the resistance for the 07+ sending units but I don't want to mess anything up. I have HP tuner but I do not know what values I need to make the 08+ sending units work on an 06 car.

The post above yours tells you how to do it. Reverse the values for primary and secondary tables.
