Does not work. Says connected but all i get is "retrieving data". That never goes away. When trying to see any of the options like rpm, or fuel settings etc, or trying to make adjustments, that is all I get. a constant "retrieving data". I have disconnected the battery, I have un-installed and re installed the app, and no changes. had to download apple version on an old iPod touch. that one seems to work perfectly. I just hate carrying 2 devices

Could not get the tuner to reliably connect to Bluetooth on 2.0.2. Did some troubleshooting to find out cycling Bluetooth off then back on, on your device does appear to fix the issue 100% of the time. This app appears to need another update, also it would be nice if the developers could set the screen to not time out with any of the menu options selected. Cobra, should have the money to fix this app and add simple things like not timing out the screen on your device. Phone is running Android 16

worked fine last season. went to go use it and it would say it finds it and connects until you click into something then says it cannot get the data. tuner itself is fine but unable to adjust or see the adjustments being made. you would think for the amount of complaints they would fix this problem. known issue but to cheap to develop a patch?
