Ratings and reviews

Greed? Got this adapter because it was the best. Unfortunately no free lunch as enhances codes cost $9.99 per make, and per year!! I personally have several vehicles and it would be more coat effective buying an adapter with this support out of the box (nevermind if you buy a new car). Simple app and interface is just that but you can do the uaual check and clear codes.

Overall, this is a fairly decent app and device. My only complaint is that it didn't detect any additional items from my vehicle, but since Jeep (or any Chrysler product for that matter) doesn't get the enhanced features. Guess that only comes from the manufacturers and I won't hold my breathe on that happening. Other than that I've enjoyed it.

Doesn't actually read the correct PID for my mass air flow sensor (with respect to fuel calculations). I get valid data from the sensor, have no means to tell the app to use that one for it. I have to use intake manifold pressure method instead, which relies on knowing the volumetric efficiency of my engine. This data is not available, and the default is clearly wrong because of a large mismatch between the app and my car's own mileage data. You also can't input formulas for dashboard items.
