MPG indicator
#181
This is all great news, but it seems like the people who are noticing a big difference really had a big difference to begin with. My manual calculations have always been close- much closer than others have reported. I'm consistanly within 1 or 1 1/2 mpg- not the huge spread that many have reported. And even though that's not balls on accurate, it's close enough for me not to be highly motivated to get this update done. And what I really wonder is if some cars had it done, or suffer less, and if so, WHY? Why are some gauges way off, but someone like me is much closer to reality?

With my city driving I average 29 mpg. My gauge reads 30- 31, at most. The only time I see a higher number on the gauge is when I throw in a highway trip. That gets the gauge up in the 34-35 range and it will stay up there over the course of the tank, even when finishing out with city driving. But all city, it has a hard time climbing to 32 and mostly flerts at 31...usually 30.4. That's pretty darn close to reality. It's interesting to me to see people getting wildy high gauge readings. I'm curious as to why some have suffered badly from this, while I haven't. I'm sure there are others like me, but I don't know. And I supoose you can say yeah, but my gauge isn't right on either- but it's a LOT closer, consistantly.

less than 2% error. That's easily attributable to different amounts of fill from the gas pump cutting off at slightly different amounts each time.

before the fix i filled the tank about 50 times and always got between 3.3 and 4.4 mpg higher than reality.

I'm not getting the update...
I LIKE the positive slant of the MGP indicator! Friends think this is an amazing car seeing it read such high MPG, and still being so much fun to drive. Mine is not too far off the mark. It is an amazing little car, and gas mileage is Great. The positive slant of the gauge just makes it look even better!
I don't plan on getting the update.

It's nice to imagine the fit would get that kind of economy but I like to know what's actually going on. The Overestimating gets annoying real quick in my opinion. It's like having your head in the sand. I'll deal with it until the car needs service but at that time, I'm getting the update.

mistake on my part .09-086 was the tsp already in my car that did not correct the mpg,according too dealer. dont under stand it if tsp did not come out until 11/18/09.
said it was in from a previous problem, but that was last year. in fairness they are still look into it.

1st tank after flash:
calculated: 32.5; information display: 33.3 difference 0.8 or 2.5% high.
Varied driving over the 8 days, 1st four days short trips averaging about 25mpg, then normal commute brought it up to 33mpg.
Much more accurate; I'll continue to check for a few tanks and then stop obsessing probably...

I had the software upgrade done this week. On a half tank fill, after roughly 40/40/20 city/highway/mountain driving, the gauge said 31.8, and I calculated 33.0 mpg. Even though I tried to fill to the same point, it was a different station, so this is probably within the margin of error, especially since it was only a half tank.
Prior to the upgrade, calculated mileage was always at least ~10% lower than displayed. I sort of miss the illusion of better gas mileage, but I prefer reality to fantasy.

I just got my first fill-up after the fix. Indicated 36.2 mpg. Actual 36.2 mpg. Can
t get much better than perfect. Kudos to Honda for 2 things: Addressing the problem, and fixing it so well. Guess I'll stick with Honda in the future. Sure beats the service I get from GM on my Solstice.

I have bad news... I have continued tracking the 'updated' gauge monitor accuracy, and even though the first fuel-up showed extreme accuracy, the subsequent ones have been off by as much as 6%. Better than 10-15%, but still unacceptable imho. Not only is it off now, but it is not even consistenty off by the same percent (or absolute) amount...

I just came back from the pump... first fuel-up since the fix.. Good News!
I've always been 10-15% off, but now the gauge says 38.2 mpg, and my calculation was 38.4 mpg. That's a tiny error really, and it could be the fact that I used a different pump for fuel-ups.
IT'S FIXED. Bravo for Honda.

I have a feeling from what I've read of others' experiences that the computer is going to be pretty close to accurate. before the update, there were two problems; the biggest problem was that the computer was ALWAYS miscalculating economy so there was never any chance of it being accurate. The secondary issue was that not all gas pumps fill the same (not controllable by Honda). Now the computer is accurate and the only place for error is with the pump. This will be the same for any car that shows avg economy. As stated, with time, i have a feeling that your AVG calculated MPG will match the average that the computer displays (over the same number of tanks.) The only time the two will really be close on a regular basis is if you fill up at the exact same pump (and there has been no change in the pump aka maintenance.) close is the best we can ask for and 1-2mpg off is acceptable. 4-6mpg off is/(was) not.
