If this is about tuning all that Blue Tooth or any wireless does is get rid of ONE of the TWO cables. Your never going to be able to see much on a cell phone size screen, unless your going to get one of the new large screen phones and I'm not talking about the new iPhone, it's too small. So with that in mind you still need to use something that has the computing power, memory size and a large enough screen size to see whats going on. With that said, IMHO anything less than a 10" screen is too small. Now where do you put that 10" screen on your bike? I love the idea of wireless but I'm not sold that it's really needed or any better than using a cable for the amount of time your going to use it. Speaking for TTS the current electronics was designed to allow it to work with both WiFi or BlueTooth by adding a secondary board into the unit. Those boards were built over three years ago and I have working units in house. There is added cost in doing it and when talking at length with tuners, most could care less about just not using one cable. Dealing with the noise that can and does come along from the high voltage ignition system, speed issues and cost kind of took this to the back burner for a project for us.
It's new, it's neat but really not going to gain you much of anything. I still like the idea of setting it up to run on an iPad or tablet but feel the phone thing will die quickly once tuners try and use it. Most guys I speak to just want there bikes to run good with no more crap hanging on it. So that really limits the market that is going to buy it, once the new fade sales wear off.
