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?

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.

Does not work. Says connected but all it does is say "retrieving data". That never goes away. When you try to see any of the options like the rpm, or fuel settings etc, that is all I get is a constant "retrieving data". I have disconnected the battery, I have un-installed and re installed the app, and nothing changes.
