You can't get better for your money. It does take time to set up a custom config but well worth the effort. It is best to create your own config, but there are sample configs available out there for E36 & E90 if you look hard enough. To get a feel though, look for the word LESSEN (Read) that way you know you are only reading information. I can't believe some of the low reviews here. This is a comprehensive tool. The ECU files are large, your car is a complex beast. That has nothing to do with the app, it just means that you can get everything you need, and more. Get yourself a decent adapter, even better get one from the author if you can. You know it will work and is cheaper that loads of others our there. Lastly if you don't know what you are doing, then don't do it. This applies for anything, not just this app.

If you are a data geek, this app is for you! Lots more BMW specific data available such as high voltage battery voltage and current, cell temperatures, and even motor torque on my i3. Works great with my Bespeak Wi-Fi OBD adapter. (I have found the Wi-Fi version to be more reliable than the Bluetooth one on several different vehicles, plus you can still use your Bluetooth connection for other things like taking or making a call while still connected to the adapter.)

Developer is clearly skilled but completely unkind to anyone who is not on his skill level. One star. Look at his reply. So check it out man, your app is entirely undocumented; translation integration is spotty AT BEST, it is entirely and wholly unintuitive, and you need to consult with a UI expert because you ARE NOT one clearly. Best of luck. "The software is free, so you can't complain" lmao
