So I know there is a way to see another readout, the B? One. Is that like a lifetime avg? How do I get to it? Just hold down the button?
I suppose I could read the manual but it always slips my mind. It's fresh in my mind now haha.
Thanks!

go to your estimated miles/km left screen, hold down the button until it reads B, and then go to the next screen to see the unreset lifetime average.
Everyone thinks its silly and needlessly complicated.
Okay thanks I'll try tomorrow.Quote:

As has been said, you can toggle between them by pushing and holding the reset button while in the Distance To Empty screen on the MID (look for the long arrow on that screen). You will see the "A" at the top of the screen go out and "B" will light up. Push again and you will see it displayed. To get back to the 'A' readout you have to toggle all the way back through to the DTE screen and push/hold the button again.
I do the same. I've also kept track of the difference between the calculated fuel economy reading and my actual fuel economy. Depending on my driving the Mirage fuel economy display can have an error of about 1 - 4 mpg over actual usage. I've noticed larger error if I do more coasting on that tank of gas.Quote:

I found the factory gauge quite accurate. It was almost always right on. I coast a fair amount. How we're you guys measuring your "actual usage"? Were you filling up at the same pump every time @ just let it click off?
Thanks all.
I let it click off. I read somewhere here topping off was bad for the emissions stuff.
OK...that worked great. Don't know why I had trouble trying to find it before. :confused:Quote:

Do you coast while driving?Quote:

I always go after the click. I have gotten almost 9 liters after the click once. I don't like filling up that much if I can avoid it.Quote:

If you get a Scangauage (which will display your instant mpg), you will observe a big difference in coasting techniques. Sometimes when the car is coasting under the right conditions, the instant mpg reading will jump from 100-200mpg to 9999mpg. I think under the right conditions, the computer can almost shut off the injectors completely when the car is coasting.Quote:

The injectors are shut off. It is called "Deceleration Fuel Cut-Off" (DCFO). On my Mirage the injectors kick back on at about 1200 rpm when I am engine-braking to a stop. Not sure if this is what you are talking about.Quote:

Cobrajet, I've noticed the same thing and thought the injectors were also shut off. However, I recently got a bluetooth OBDII adapter that lets me monitor stuff while underway and I've noticed that I get high instant fuel economy numbers while coasting in gear but when I shift into neutral those numbers go up. It goes against what I thought DFCO was all about. Have you watched instant fuel economy while coasting? Maybe I'm missing something.Quote:

If you shift into neutral, you're disengaging the engine from that free energy and the car then has to find some other energy to keep the engine turning, so it switches to idle and kicks the injectors back on. if you want movement with no fuel you either have to leave it in gear while coasting or turn the key to shut the engine off completely.Quote:

Thanks! I'm just reporting what I see on my OBDII app and find it contradicts the expected DFCO fuel savings.Quote:

Someone here put a meter to one of his injectors and reported that they do not get any electrical voltage during what they determined to be DFCO conditions.
Good to know but it still doesn't explain the OBDII fuel consumption while coasting in neutral v. DFCO.
In the end it's all good. I still get GREAT FUEL ECONOMY IN A CHEAP RELIABLE LITTLE CAR!!!!!
Found it. It was MightyMirageMpg: DFCO explained measured and how to utilize itQuote:
