About this app

Introducing the latest and greatest bootmod3 app!

Had a lot of difficulty authorizing vehicle. Took several days of back and forth with ProTuningFreaks to get things to work using their latest and greatest $100 WiFi adapter. App, wants connection to car and Internet at the same time, which is impossible while using the BM3 adapter with Android. In reading the user manual, the app has been updated, and the manual hasn't, which causes discrepancy in how to operate things. Also the screenshots in the manual do not match what you see on your phone.

Hi Chris, unlike iOS, unfortunately Android doesn't allow simultaneous connection to both internet and the vehicle. It isn't a limitation of our hardware or app, its just how Android networking works. bm3 connectivity guide is on our website in the main menu which describes connectivity and all of this in detail.

Bootmod3 you are truly amazing!! My car feels so alive after tune! Power gain which I got is something I never would have dreamed of; plus my mileage is off the chart as well (apart from the times when I just go crazy due to extra power). Your support has been great as well. 5 stars is understatement, wish I could give 99 stars.. for last 100th Star.... one small tiny improvement of having full offline capabilities, I am still using wire for cellphone flash.

The app works well. And customer service is the best I've seen from any company ever. Still unable to flash the car though. By the time I can I will be close to $1000 to get it running for my car. They do mention cables and adapters needed. But not mention the $200+ sending off the DME to have a bench unlock for some unknown reason. Have a 2015 so nowhere close to the 6/19 cut off. The app has changed compared to the online instructions provided so navigation per instructions can get messed up
