I should have read the online owner's manual first - it answered all of my questions except for the firmware upgrade.  There is a reset command in the menu to reset the trip functions and the gauge does not re-zero when powering off.


General Discussion / How to reset MPG, etc questions

I'm close to purchasing but have a few questions.  Since I don't see a reset button, how is Ave MPG calculated and can it be reset during a trip?  Or does it reset every time the vehicle is turned off or can it be saved to keep a running average MPG over several months?  Also regarding the MAFS input air temperature, is this the same reading you get in most cars for outside temp, or will this air temp be slightly off from outdoor ambient temp?

Looks like a very nice product.  If you should update the firmware in the future, can an older unit be updated?
