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

tuner works fine if you just use there settings. the app won't connect to my android s25. connects my iPhone 16 but can't make adjustments. The app used to connect to my s23 but now it connects and I can't make adjustments. Ever since they did the update it doesn't work. Going to throw this tuner in the garbage and purchase the dynajet power vision. when is this going to be fixed, STILL DOESN'T WORK.

in 7/25 I could connect and edit as well as monitor. currently 10/25 it will say it is connected in the app but only the red light is on inside the module. Then when i click on anything to edit or monitor i get an error screen that says to reconnect. I have already disconnected unit and reconnected, power cycled samsung phone as well as reset Bluetooth. Still will not connect to module. Is there a fix????
