I'm thinking about putting a fuel cell into my truck and I'm wondering; can HP Tuners be used to change the parameters for the fuel gauge? In other words, can I take an aftermarket sender, hook it up to my gauge wires, change the parameters on my PCM and have my stock gauge work correctly?

 

Yes, it is in the Fuel System tab, between the Trans Diag and (fans) System tab.

 

Right on!
