ScanGauge
 

Has anyone used one of these in their OBD-II cars? I was reading a discussion on another forum regarding the uselessness or lack of gauges (coolant temp in particular) in modern cars. This comes despite the fact that modern electronics measure/track/use more information than ever.

Thoughts?

Yep, I've got one. It's pretty cool. What do you want to know?

I have the ScanGauge OBD-II scanner installed on my 2007 MazdaSpeed3 and I find it very useful!

It works as a code scanner and will reset codes which is nice to have. It's also got a great trip computer if you are into that. I use mine some but seldom look at it, really.

99% of the time I have mine set to display these 4 attributes.

rpm, mpg, mph, coolant temp.

But it will display

Fuel Economy
» Fuel Rate
» Battery Voltage
» Coolant Temperature
» Intake Air Temperature
» Engine Speed (RPM)
» Vehicle speed (MPH)
» Manifold Pressure (not available on some vehicles)
» Engine Load
» Throttle Position
» Ignition Timing
» Open/Closed Loop

I suppose I want to know if it is legit or a POS. I hate the fact that my wife's RSX-S has no real gauges. I don't really need the extra gauges, but I like to know what is going on.

Also, a trip computer seems like such a no-brainer on a car with OBD-II. Do find the trip computer functions (MPG, distance to empty, MPH, etc.) are relatively accurate?

I like this one:

List is $169. The factory sells them on Ebay for $159.

My ScanGauge is accurate, useful and well worth the $ I spent for it. I've used it to reset a few bogus CELs for my wife's Mazda CX-7 and my MS3. I like to keep track of mileage, etc... and it is much more accurate then the onboard gauges...

The gauges work very well. The unit is small enough to not be too bulky, and the display is large enough that the gauges are easy to see. It's nice that the display color (when the lights are on) is configurable.

The trip computer is very accurate as far as I can tell. One of the functions will tell you how much gas you have left in the tank. I find that it's very accurate. When I fill my tank the thing generally tells me exactly how much gas I'm going to put in.

Thanks for the info, gents. Now I just have to explain to my wife why her car needs one of these things... ;-)
