Has anyone heard of the iOBD2 mini?
I had another post about this but no one responded.
It's a Bluetooth dongle that plugs into your OBD port that links to your smartphone. It gives you real time engine information and other features such as gas mileage, MAFS, speed, idle. The cost was around $22 shipped from xtoolstore.com but I'm sure it can be found elsewhere.
It's just for monitoring and reading engine codes and data. You can not tune with it. I think it will allow you to reset CEL codes however.
I took some video of it with my iPhone, if I can figure out how to edit parts of it out, I will post it on YouTube and update with a link here.

I just ordered a second one for another vehicle. If anyone takes the bait, I suggest adding to your cart before clicking the buy now button on the bottom of the page!
