User Reviews

User reviews indicate the Screamin' Eagle Street Tuner app is unreliable on iOS: frequent crashes and Bluetooth disconnects, poor error-code reading, and flaky tune loading. Firmware updates often worsen these issues. A minority report smooth operation and modest gains when it works, but overall the negatives dominate.

Pros

When the app/tuner is functioning, live tuning and gauge data can be usable.
Autotune can deliver smoother throttle and reported gains (e.g., smoother performance and potential HP/torque increases).
For some setups, it is an official path to tuning that can preserve the Harley warranty.

Cons

Bluetooth connectivity is unstable, with frequent pairings and disconnects
The app frequently crashes, including during tuning or when viewing gauges
Error codes/DTC reading is unreliable or non-functional
Tuning/calibration loading is flaky, often requiring many attempts or failing when renaming files
Recent firmware updates often regress functionality and introduce new bugs (gauges missing, crashes)

Recent reviews

As far as simple tuning it works. Can be a little glitchy. It for sure works better on iPhone (as does most everything on Harley I’m finding).

Overall it works well. I was able to tune my bike very quickly and everything went very smoothly. The custom gauge screen is very nice to have as my bike is a soft standard and has limited gauges. The app UI is a little dated and not the best looking, but it does the job just fine.

Well on a new touring bike one have to turn off infotainment just to be able to connect to the tuner but even when you connect it can’t do basic functions like read error codes; when you try you just greeted with a pop up “something went wrong”. Once the warranty is up SEPST with that app goes to garbage bin.
