Ratings and reviews

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.

Tool has worked well enough for 5+ years. Intermittent connection issues here and there, learned a few things. Can't seem to use mobile data while connected to it... On any device. MX Wi-Fi Version I was hoping for firmware update, but it appears to be pretty much unsupported at this point. Still works with this app, I'm just factory resetting the device nearly everytime i need to connect to it. Still useful and well supported by the application. Best money I ever spent. Thanks for the product!

Once I purchased the $15 enhanced features for my Prius, this is the ONLY non-Techstream app I have found that can pull, view, and clear ALL codes. Incredible value. Now, if only it could provide... * Ability to display a couple dozen sensor values on a single screen report * Ability to attach different ECUs to different display pages, to make it easier to look at various data sets. I can get all the data to be sure, but it is not easy.
