Does anyone here use a Scangauge 2 or other ODB 2 unit?I'm considering adding one for my next MH purchase, and wondering how useful it would be (in people's opinions) as something to mount on the dash. With the Scangauge X option, if there is a code thrown, I'll have the ability to see what it is, and clear it.

I mounted a Scan-Gauge-II in our 2007 Ford E350 rig a year ago and used it for the first time last summer on our 4 week Out-West trip. It is a nice tool to have to help critique driving technique for better fuel economy. I especially appreciated the TPS (Throttle Position Sensor) which the number readout doesn't mean much by itself except to determine how far down I am pressing on the gas pedal. After an hour of learning the TPS behavior, it became quite informative along with all the other data.I easily mounted the Scan-Gauge-II with the provided Velcro, on top of my backup camera seen here in a very easy to read, yet out of the way location. It feels like part of the vehicle. I kept the original SG cable coiled up by the OBD-II, and strung an RJ45 cable (standard computer internet cable) between the OBD-II and backup camera. If I want to use the Scan-Gauge elsewhere, I unplug it up top and down below and use the original SG cable temporarily on another vehicle.Mounted the Scan-Gauge-II herePermanently fished a 6 foot version of this cable from OBD-II to the mounting area.Chained the SG cable to the RJ45 cable using this

If you have a smart phone, download Torque. Does everything the other gages do at a fraction of the cost.

Having an OBD2 reader is invaluable when driving cross country for the immediate and ongoing fuel economy outputs.I've been using an ELM327 compatible OBD2 reader with wifi, and connecting it up to my iPhone or iPad with Dash Command.You can find similar OBD2 readers online for under $30, and the Dash Command app was $50 when we bought it. I like not having extra cables to mess with, and the interface on the app is pretty rich.Both have paid for themselves in my being able to self diagnose and clear codes for state emissions testing.

Have a Scan Guage2. Monitor Trans temp, engine, etc. More accurate than dash gauges.

I have an early Scan Gauge. And a GPS. My speedometer, GPS, and Scan Gauge do not read the same mph. The Scan Gauge is the only one that is right.Dusty

Permanently fished a 6 foot version of this cable from OBD-II to the mounting area.
