Just got the Ultragauge Blue delivered from the US for AUD$150, took about 5 days by Fed Ex. Very easy to install and sync the ultragauge to my iphone using bluetooth, no trying to hide any wires with the wired units, although while the gauges are being displayed, the iphone screen stays on and will drain the phone battery in a short time if not plugged into an usb.
The guages are displayed on the phone using an app. Once you get the hang on how to work the app, the gauges can be fully customised; # gauges per page, analogue/digital/graph, size, color and probably others ways, still working through the 80 page manual!
I mainly wanted the ultragauge to measure the Atf temp while towing. I got the PID code from the Paj forum and manually entered the codes, very easy and I think it is working.
This very cold morning (-1C) in Canberra, both the water and Atf started at 19C; 20 minutes on the highway, Atf = 50C; in town, Atf = 58-64C. That seems about right.
