Question: Can the overhead "computer" be adjusted
My actual/calculated MPG is noticeably different than shown on the overhead. I.e., overhead shows I'm getting close to 21-ish. Hand-calculated shows otherwise (17-18 range).
Question: Can the overhead be adjust so that it is more/closer to accurate?

There is a tsb for the overhead not being accurate and fuel mileage, the dealership said that they reflashed my ecm for this tsb per my request when I had it there for the air bag recall. I have not noticed any difference.

...ah, ok... Yes, I still need to do the air bag recall thing. I don't know if I want them reflash my computer ...everything else is working just fine. Thanks!

I think I had that same reflash done when I had an 03, and I didn't notice much difference.
The OP having an 06 I would think it has the updated software.
I don't know if any vehicle has a mpg guesser that is accurate.

Seems like they flashed it every time it went into the dealer. I'd say 3-4 flashes since 06 sounds about right.
I try to avoid the dealer, but sometimes I don't have a choice.
