So...here is a qwuestion for you all....is 99.9 the highest mpg that can show up on these units, or are they limited to something lower. I WILL NOT get near that with my Geo, but have been getting from 52-61 depending on the conditions and how it is driven. I'd hate to buy something that has a limit of 40 or 50 mpg....anyone know?

AND...
I need to update my sig....the SRT4 has ran a 12.17 at 115 mph still on street tires and 93 octane fuel; the Voyager now gets 26 mpg with only replacemnt of the stock air filter with a three layer home made section of screen mesh; the Geo gets a max of 61 mpg, not 63....AND, I won the Stick Shift Nationals in October to raise my number of NHRA/IHRA Championships to 36, using my mechanics plain jane Neon while I was awaiting parts for the twisted in half input shaft on the SRT4 at the next to last race.

Decelerating in neutral at 140km/h with the engine running I saw a reading of 292mpg in my old Pontiac Vibe.

On flat ground with a steady throttle at freeway speeds I can keep the instant mpg reading from jumping more then .2mpg.

I found that with my winter tires I had to up the EFF number to 93 to keep a relativly accurate reading.

Since I traded in the Vibe, the ecometer has had a new home on the dash of the Silverado. Still works great but one thing I noticed is that, in the Silverado, the instantanious reading doesn't jump around nearly as much as it did in the Vibe. That can probably be attributed to the fact that (at least with the manual transmission Vibe) the throttle is EXTREMELY sensitive to any change in position. 5spd stick w/4.31 final vs 4spd auto w/ 3.42 final. 2.66 times the displacement...

Still, for what it is and what it does, it works quite well.

Autometer unstable?

I have a Factory computer onboard, and even starting my tripcomputer at 50 miles/h with cruise control (electronic), the instant fuel consumption is highly variable, even in an apparently flat pavement.

Only average mpg is representative. The other is illustrative as show you instant changes of pushing the trottle, climb or going down slope.

The fact autometer varies instante mpg means it is GOOD, not bad. If it didnīt varies its real time mpg, should be lying.

Jumping fuel flow meter

...I don't know if the problem is with the unit or the car interface (2009 Pontiac Vibe 1.8L with CAN-OBD-II) and little help comes from Auto Meter (they were VERY prompt in responding before the sale, but are now disturbingly silent after the sale). I'm trying to find out if others are having similar problems either with the unit of with the unit installed on Pontiac Vibes and Toyota Matrixs and Corollas.

...the good news, however, is that once "calibrated" the MPG-avg reading displayed at the end of a tankfull of gas is quite close to the actual tank-fillup value.

...what vehicle are you thinking about installing it on?
Your meter is very accurate as instantaneous fuel consumption IS variable due to many factors. Only mean mpg tends to be stable in ANY good flow meter.

What are the connections it needs? Is it a OBDII meter? Or is it of more general use? Price?

The Auto Meter 9100 plugs into and uses the underdash OBD-II connector.

FWIW, the ScanGaugeII™ meter is MUCH, MUCH smoother in its displays of both instantaneous- and average-MPG values...and-d-d-d, it does NOT drain down the car battery when the car isn't used in a week.
