I have a ScanGauge I that I have had and used off and on for probably 3-4 years or so. I bought it when they first came out. It still works fine. The only flaw that I know of is that if you use if for several days in a row, you have to reset it - seems to lock up or something.
The ScanGauge II sells for $169 I think and is nicer and not as bulky. I'm thinking $50 for the Scangauge I, or best offer. I don't have the original box anymore, but I think I still have the manual. I'll pay for shipping.
I don't have a picture handy - I'll see if I can get that. Yes, it displays quite a number of OBD II parameters: Fuel Economy, Fuel Rate, Battery Voltage, Coolant Temperature, Intake Air Temperature, Engine Speed (RPM), Vehicle speed (MPH and KM/H), Manifold Pressure, Engine Load, Throttle Position, Ignition Timing, Open/Closed Loop, etc...
It also allows you to read and clear OBD II error codes - a feature I've used a lot as I've messed with sensors and stuff like that.
