Fine Tune the Average Fuel Used Counter

Recommended Posts

My OCD is kicking in.  My fuel used counter reads 1 to 2 miles per gallon better than actual.  Using the gas station gallons pumped and a calculator the two don't coincide. 

I had the same deal in my Mustang and a fellow had a hack to get into the computer to adjust it in tenths of a mile.

Question is, has anyone discovered how to do it with the MKZ?

Thanks!

Just for general info a Mustang guy figured out how to do it on the 5G Mustangs.

I've checked by hand several times and the difference between the two methods never differs by more than .1 mpg.

Has anyone gotten their Z into Engineering Test mode?

car mpg / gas pump mpg

42.4    45.0

40.1    36.4

42.5    40.4

40.2    38.1

42.1    38.7

41.9    39.7

39.1    42.1

No idea what's going on.  Probably the same computer guru wrote this code that did the stock market black box trading code. 

I've left Trip 2 untouched since I got the car and it's showing 41.1 mpg over the last 2,000 miles.

I've watched EV miles and those sort of make sense when considering if the majority of driving was stop & go or 70 mph.
