...I'm almost at the point of NOT recommending this device, because, so far, only the MPG-avg mode seems to work acceptably. The other three modes (MPG-inst, MPH and RPM) all "jump" around continuously, never settlling down on a fixed number, almost regardless of what the car/engine is doing.

...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?
