Can anyone give me guidance on how to adjust the fuel economy calibration on a 2017 Expedition? See lots of info on how to do it on an F150, but those same options (AFE Bias adjustment inside the Engineering Test Module) doesn't appear to be present on my 2017. Any ideas? Current readout is roughly 7.5% optimistic vs hand calculation, and very consistent tank to tank.
