Maxitrip Auto Computer
 

I recently bought one of these from Princess Auto and it seems to work really well. I am looking through their flyer and it is on sale for $79.99, their site addy is Princess Auto | Quality Selection Service & Value it also is able to clear trouble codes and tells you more detailed info than the speedo heads do in most vehicles.

I hate to be the one to reply to my own thread but hear is some more info:

How is it for night/sunny visibility?

it has very good visibility both at night and during the day although I need to play with it a bit more, it is almost too bright for night driving

I bought one two weeks ago. It work awesome! Fully calibratable at each tank fillup. Yay Princess Auto!

Yea I love and hate Princess Auto, you can't go in there and not buy something. Maybe that's why my wife got a restraining order on them for me, lol!

...let us know how "close" the meter MPG value is to your TANK fillup MPG value.

...are there provisions for both MPH (gears) and TIRE (diameter) calibrations, or just FUEL (gallons) at fillup?

there are calibrations for tire size. It was very close to what I figured I had gotten on my last tank. I am using it in my '06 Aveo and figured my mileage out to 41 mpg

They are now $59.99, I jsut got my 2nd one on Saturday. Going back for a 3rd next week. Can't beat the price and I use them for more than just mileage.

$60 is about the price of a decent error-code reader, so that's very competitive.
