Honda Hybrid Vs. Toyota Hybrid

Yes. It's because it doesn't know about lean burn. It cannot, because the car's OBD-II port doesn't say anything about it. Any OBD gauge will have that problem.

If your gauge kept resetting maybe you had a defective one. I've never had that trouble in 7 years with two gauges.

The DFCO thing was fixed in a later revision.

Specifically, from what I have read on here, the gauge only knows how much air your engine is using, not fuel. Without knowing the engine's current ratio, it cannot correctly estimate.

thanks for all the info guys!

Interesting fact: the Fit has the same 150 mpg max that the Insight has. It's just LOT harder to see it. I did once, rolling downhill.

I have seen 150 MPG or higher in my Forester when coasting. At idle, my engine uses around 0.24 GPM, so I would need to be rolling at 37.5 MPH.

However, even though I see moments of extremely high MPG, my average is not too much higher than EPA, which is lousy.

Sensible design: develop one part, use it for many applications.

It's like the people who can't understand why drive-up ATMs have Braille keypads... (The reason, of course, is that it's cheaper to use one standard keypad than to make a special one for driveups.)

In Yourup the MID shows l/100 km and I'm pretty sure it will show 0.0 l/100km if I reset my trip counter and push the Insight for 100 meter.
Could do something like that coasting at speed too of course, might do that tomorrow as I accidentally messed up my Trip A (auto tank reset) measurement anyway.
Bound for infinity

EDIT: No, it does not! I did reset my A counter when coasting down a highway exit, and it just kept displaying --.- l/100km until it went into ICE mode again.
Usually the numbers appear after 100 m, now it kept to the dashes for over 500 m. When I booted it as the lights changed, it jumped to 0.6 and upwards.
I'll see how low it can go on my next commute.

EDIT: it goes right down to 0.1 l/100 km.
0.1 l/100km is about 2349.285270354257 mpg, give or take a bit.
Anyway it simply refuses to show 0.0.
Think it finds that kind of FE really dashing

it is not true that all OBD port devices would get confused by lean burn. The OBDII C&C, an OBD device that is specifically designed for the first gens Insight and Civic Hybrids has no problem with lean burn. It also shows AFR, though. The Insight is great if you don't need a back seat or carry anything heavy (350 pounds including driver and passenger). It can also run just fine with no hybrid battery, and because of its extreme light weight and lean burn, it will still get killer mileage. plus, with the aluminum frame, you won't have much trouble with rusting (well, the fuel door release on mine likes to rust from lack of use ) If you do, the Civic and Prius are both good choices. The Civic would be a better driver's car with its optional manual if nothing else. You have to take care of the battery though. I built a low power grid charger/balancer based on the designs suggested on Insightcentral.net, and I have no problems with my 13+ year old battery. The Prius is probably more trouble free, but I always got the impression that it is more of a transportation appliance than a car.
