I have an old file that tells how to correct the MPG display. The file probably dates back to my '17 or '20. Is the correction still available for a '23 Lariat? Any instruction updates?

 

Here you go! I set my to 965, as the truck was around 1.5 MPG more than hand cal.

 

What if the truck readout is lower than actual? I routinely get 23.8 by hand calculation and 23.3 computer calculation. If I only use three digits that would be 102.

 

Change the OEM 1000 value to 1102.

 

Gracias

 

I actually thinkyou would change 1000 to 1020...
The AFE Bias is just a percentage like baseball averages. If the calculated is the same as displayed, the value is 1.000. Multiply 23.3 by 1.020 and you get 23.766 (or rounded 23.8). If you multiply 23.3 by 1.102, you get 25.5664 (25.6 rounded), which is way above your calculation.

 

Yeah, you are probably right. My bad.
