Like Paul I have been running one for a while, it's been a great improvement over other ODBII gauges I have used.
I have only ran it on my 05, but it's very easy to use and learn.
There have been several questions about multiple UDC tunes on a Touch, so here is how mine looks in the UDC menu. I have 3 loaded on the Touch. It's not shift on the fly, but still a easy and fast change if needed.
Some other things I have noticed the Touch does that the S-06 doesn't do is it keeps your PoD setting between tunes and remembers the tire size, even if you go to stock and back to a tune.
Well my main question is if I go ahead and get one now will it be upgradeable to read fuel pressure since it will be an external input. Or do I need to wait for the fuel pressure capable unit to come out?
