your sprinter has a maf
did you get the fuel economy calc to work?
Yes I did, unfortunately it didn't bring the average (or instantaneous) up any where near my calculated average. The calculated average is running just over 19MPG (over 6000 miles of fill ups) while the average MPG on the UG is about 10.8. The (on the highway) runs from about 8 to 15 with the normal about 10 (16 to 21 down hill).
Oddly enough when I first start to decelerate the instantaneous goes way up but under continuous decel ( like long hills) the number starts to drop by a large amount.
The fuel economy calc was over a 20 mile stretch of winding, hilly roads ( I-84 in NY). They aint no straight roads in the north east.
The next time I get to PA going to or from a job on I-80 I'll try for a 200 mile calculation.
Haven't tried the VE enable yet as the UG ADMINISTRATOR suggest so will have to try that, I can always disable it if nothing changes for the better.
