Anyone ever heard of it? Plugs into obd-2 port, sends wireless signal to iPhone or iPod and there is a free app where you basically have a dyno, obd-2 scan tool, full and functional gauge readouts (AFR, boost, etc..) all for $180. Seems like a good buy just curious if anyone tried it or knows anyone who has. I think you can download different tunes too or tune yourself maybe? Not sure. Thoughts?
