I still use my scangauge2 on my steering column, but if anyone has an android device, you can buy the
Torque app and it has a ton of gauges available. In addition to the app, you will need to buy a
Bluetooth odb2 connector for it to work. The BT adapter I linked to is the one I purchased, and it has worked well for the last 4 months.
I don't have a recent screenshot, but here's an early one from when I was messing with it. Just to give you an idea what it looks like. There's about 80 sensors it can read from, and a bunch of different style gauges. You're not stuck with just digital. And it has a bunch of skins and themes.
