Finally got to install the Innovate Motorsports OT-2 Tool in my Tundra this week. Install was quick and painless with no issues. I am using it with the "Logworks" app for Iphone. I have been impressed thus far at the speed of the unit and it's accuracy. Glad I had it installed yesterday as I replaced my K&N Intake with an AFE Intake and ended up throwing a code. I was able to view the code and reset it with no problem. Nice item to have as you can monitor just about everything on the vehicle and also record this data. Took a road trip this morning and used the Economy Meter to track my fuel use and MPG's. If anyone is interested or been playing with the idea of getting one I must say it is worth it. The unit cost me $180 bucks and was at my door three days after the order was placed.
