Can I undo hitting the reset button?

[mike0422]

While showing off the car I accidently hit the reset button. Is there anyway to get my current tank mileage back?

[SomervillePrius]

nope. :-(

Sorry.
I had to take Priapus in for work and they had to disconnect the 12v which wiped everything out.

I ran the tank to the normal refill level (usually one bar blinking). Then, using the ODO reading, I calculated the number of miles driven between refills. Using the amount of gasoline I refilled with, I was able to calcualte the MPG. It shouldn't be too far off what the MFD would have shown.

For other people with reading comprehension issues, he's talking about the "amount of gasoline [he] refilled with" previously.

Reading this thread I first read "Can I undo by hitting the reset button" and it reminded me of a xbox360 game called full auto where you have a rewind button for when you crash your car

Did I misread/misunderstand or are you saying that my post was difficult to understand. Neither one would surprise me much.

In the event that it's the latter, allow me to explain a little better since I did seem to skim quite a bit up there.
We'll start with a completely filled tank and an ODO showing 15,478.
Approximately 200 miles into the tank, I hit the [RESET] button or whatever. The numbers on the MFD are now officially bumpkiss.
Refill occurs about 300 miles later and requires 9.8 gallons. The ODO shows 15,982.

This means that I traveled 504 miles, consumed 9.8 gallons, and averaged a paultry 51.43 MPG. It's purely a measurement of how far I drove since the last refill and how much gas it took to get there. Unfortunately, if you do not have the ODO reading from the most recent refill, you can't do the math.

Okay, so apparently I read it the first time the way you meant it. But with fillups varying so much with the bladder I thought I might be reading it wrong. I then noticed you didn't actually say to refill the car. And that actually made more sense to me, because I bet that the actual amount of fuel in the tank whenever the last bar starts blinking is much more consistant than the amount of fuel in the tank whenever it has just been filled. Actually, I guess the way you're talking about doing it depends on both amounts being consistant, so using the previous fillup amount does seems like the way to go.

Anyway, I found it pretty interesting to split up a couple tanks, and reset after each little trip. Okay, it's 20 cents to go to the library and back, 50 cents to work this way, 75 cents that way. I used trip A to get the mileage to the tenth (then added .05 to round correctly) and trip B to make sure I was still accurate for the whole tank. You can check out the 2nd sheet in my spreadsheet if you're interested.

I'm keeping a lifetime average on the computer, so I reset occasionally like jeneric does.

(Sorry, I don't reset, but I reset the MFD.)

[Smug]

Just a note.

Be careful when cleaning the MFD. Don't clean it when on this screen, switch to the map or consumption screen. Have read about "premature reset," though I never experienced it myself, of course.

[rccraigb]

I'm still on my first tank and wondering if I should press 'reset' when I ultimately stop for a fill-up. What do most people do here? Reset with every fill-up, or never reset to see the lifetime average?

No comment on 'premature reset'.
