When the application connects it works well. Unfortunately, every time I try to use a function the device disconnects and won't reconnect unless the bike is restarted. Once it's connect the same problem. Please update. Great product WHEN working with app.

Got it installed. What I have had success with was Bluetooth does connect quicker at startup. It will pair later during the ride but it is slower to establish connection. I figured out how to make adjustments, after unlock and disclaimer swipe either up or down on screen. For some reason it wants me to do this on the left side of the screen. Odd but ok, manageable. What I would find useful would be if I could capture a rides metrics and look at it on my comp. it would be unsafe for me to try and focus on the screen while riding and I have no desire to take it to a dyno. Right now all I can view is real time data, great at startup and shutdown but useless for figuring out tweaks or looking for telltale signs of issues. In the end I bought this unit expecting it to do the tweaking for me and I see minor differences the more I ride so it is happening to some degree but again if I could have a rides data available from say my ride home from work on any given day that would help me.I am happy with the unit either way. My bike rides better, I have better throttle response and no backfires just like COBRA told me it would fix.Works great but room for improvement!!

I can monitor things with this app but it will not let me adjust anything… Literally lets me unlock gives me a warning that if I change anything that it’s my own responsibility and then when I go to change it, absolutely nothing happens !!! this app is horrible!!!And the tuner is not very good as well! because now I am stuck with a bike that jerks and screws around when I’m trying to just cruise because the fuel is all effed up and I can’t change it because the app doesn’t let meUpdate 6/8/19 This app still does not work at allI deleted a Tonna stuff on my phone to free up storage hoping that maybe it was my phone that was making the app not work correctly… But unfortunately this app still does not work at all.It allows you to monitor things but it does not allow you to edit/change anything whatsoever. ☹️

I have a low screen timeout setting to save battery and this app unfortunately doesn’t keep the screen awake which is quite annoying.There should also be some sort of basic set of instructions on how to tune the neutral and develop fueling with this app.Aside from those two complaints it is a pretty cool app.
