He tried from my phone and also could not get it to tune. They had to connect it to their computer to get the tune loaded. I was told the app doest work on newer phones. ### 2/5 — Bugs bugs bugs *2026-07-18* Common Harley. Fix this. This thing is so buggy that it takes away the enjoyment of auto tuning. I am doing everything required: turn my Infocenter off, turn Bluetooth off on the bike…it still gets stuck every time. It takes multiple tries so get into auto tune session. Also, speedometer doesn’t work which is dangerous. I understand the rider aid being off but speedometer is important. I paid almost $500 for this thing. I would expect for it to work. ### 2/5 — App is slow and cuts in and out *2026-07-02* App is slow with Bluetooth connection and cuts in and out so often I just shut it off, even with a good wifi connection & Bluetooth and with bike sitting in my house garage then tuning they say a couple minutes ha ! I would start the download process for the tune and have walk away keeping everything in close proximity and return after 30 minutes with out it being completely done , tried deleting app reinstalling, rebooting , at that point I’m frustrated and shut everything down ! Waste of money if you ask me ! ### 3/5 — Works ok *2026-06-07* 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). ### 2/5 — Absolutely nothing positive to say *2026-06-03* 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. ### 1/5 — Bluetooth *2026-04-04* Fix the Bluetooth connection, it fails more than it works. Fix that and the app is ok but as a tech this cost is time. ### 1/5 — Doesn’t work *2026-04-04, version 1.2.1* The app simply doesn’t work ### 1/5 — Bug bug bug Bad tuner *2026-04-03, version 1.2.1* Tuner difficile a jumeler erreur de connection ´´arret critique erreur de batterie ´´erreur de lecture. Je conseille Pas ca a personne ce pro street tunner est tres Mauvais et Danger pour ECM moi jai une tres mauvaise experiance ### 1/5 — Engine error codes *2026-03-25, version 1.2.1* The Error Codes use to work but not it just tries to load forever without showing anything ### 3/5 — Street Tuner *2026-03-09* A few issues with it crashing, it recognizing my phone, and lagging out when trying to Install a tune but overall it’s ok. I wish it had a specific tune for stage 2 with 2in1 exhaust. ### 1/5 — So many bugs *2026-03-09, version 1.2.1* I am unable to read error codes on my 2025 road glide with this stage 1 tuned SE tuner and app. ### 1/5 — Worst app ever *2026-03-08* Is telling me that I have my bike on the cell phone pair to a different tuner. I’m so frustrated with this app. ### 1/5 — App is junk *2026-03-08* App never works right. Always get an error message when trying to read DTC codes. Never works right. Try to calibrate with a tuning file for a stage 2 and getting error messages unable to load calibration try again later. Never works. Worthless app and now back to the dealer because it’s not loading what my DTC is in the infotainment system either. All modules show 0 DTC yet my check engine light is on and running on the cylinder. Do better Harley ### 2/5 — HD needs to do better *2026-02-28* Harley definitely needs to improve this app. When I go to unit at any given time, I have to remove the app and reinstall it before it will connect to the pro Street tuner. When working within the app itself, and trying to go from one screen to another, I literally have to tap on something 6 to 10 times before it will respond. No, I do not have a screen protector on my cell phone, so that’s not the issue. Like a lot of manufacturers, it’s an interesting time right now. Fixing the big things is actually easy to do, fixing the small things is a little bit more challenging, but it seems Harley’s not worried about the little things. ### 3/5 — Fixed till you broke it *2026-02-22* It was running ok. Then with the latest update it lost the gauges on the toolbox. Please re-fix it again ### 1/5 — impossible to connect after new update *2026-02-19, version 1.2.0* such bs. cycled bike no less than 85 times with varied app/power timing and wont connect. did everything the web says and more. wont connect. ### 1/5 — Typical Motor Company Trash *2026-02-18, version 1.1.11* The only reason anyone would use this is to keep warranty and try to correct the poor fuel management from the factory. It does not do the latter, only the former. It is finicky to connect, thinks it has to re-pair every time you use it, doesn’t pull error codes like it says it can, HD doesn’t update it like even free versions are, the list goes on. I can not think of one good thing about it. And the worst part is: This is exactly what I expect from the HD. Good job guys, performing as expected. Using this on my 8th new HD, and the last new HD. ### 1/5 — Worthless *2026-02-17, version 1.1.11* Took 8 tries to apply a canned tune. Then when I try to look at gauges it crashes every time. ## Most critical reviews (10 lowest-rated) ### 1/5 — Please fix bugs *2026-07-25* Please give us a location where we can updated on the performance of the app I hate to give bad reviews but I can never check DTC and the amount of errors I encounter while attempting to start the smart tune process and actually get passed downloading to bci part is unreal and time wasting ### 1/5 — Garbage *2026-07-16* Worst 400 dollars I’ve ever spent. Won’t connect, and when it does I get a litany of errors. Now it can’t read my VIN. Time for a PV4! ### 1/5 — Frustrating *2026-07-14* It works after a lot of wrestling and retries. Needs improvement. ### 1/5 — Absolute Trash *2026-07-02* The inconsistencies you will have in connectivity will frustrate you beyond belief. Just take it in and have your system tuned or buy a better tuner. Very disappointing but consistent with Harley continuing to create trash the last few years. ### 1/5 — Not reliable *2026-05-27, version 1.2.2* It is very buggy. Hard to connect with error messages without any explanations. It cuts in the middle of operations and it does not remember where you were, so it is a full restart every time. Absolutely not intuitive to use. Even with the latest update it is pretty useless. Nothing can be done in the app without being connected to the BCI. ### 1/5 — Clunky Software and Unstable Bluetooth *2026-05-25* 1 Star I rarely leave negative reviews, but after owning and using the Screamin’ Eagle Pro Street Tuner for over two years, I cannot recommend this product. I work in IT professionally and have extensive experience troubleshooting hardware, software, Bluetooth connectivity, and firmware-related issues. Even with that background, this tuner has been one of the most frustrating Harley-Davidson products I have ever used. The biggest issue is Smart Tune via the iPhone app. The Bluetooth connection is unreliable, pairing frequently fails, and the app regularly loses connection during tuning sessions. At times the BCI reports as connected in iOS while the Harley app simultaneously reports that it is not paired to the motorcycle. Firmware updates, pairing resets, app reinstalls, and network resets do not consistently resolve the issue. The PC software works more reliably over USB, but Smart Tune functionality depends heavily on the mobile app staying connected over Bluetooth. Unfortunately, that part of the system feels unfinished and unreliable. For a premium-priced tuning solution from Harley-Davidson, this should work far more consistently. The tuning ecosystem also feels outdated and overly complicated: * separate PC and mobile workflows * confusing firmware/update procedures * poor Bluetooth recovery behavior * limited troubleshooting guidance * unreliable auto reconnect functionality When it does work, the tuner can produce decent results. The problem is getting it to work consistently enough to trust it. For a modern EFI tuner in this price range, I expected a polished experience. Instead, it feels clunky, fragile, and overly dependent on unstable Bluetooth communication. I genuinely wanted to like this product, but after two years of dealing with these issues, I would not purchase it again and cannot recommend it to other riders looking for a dependable tuning solution. ### 1/5 — Clunky and outdated *2026-05-16* There is no reason an interface should be that clunky in 2026. ### 1/5 — Crash City *2026-04-20* This thing crashes out every time I try to connect to bluetooth for the pro street tuner. And the odd chance it does decide to connect, the second you hit “next” it loses connection and crashes out again. I expect more from one of the oldest motorcycle brands in the world. I didn’t have a single expectation before using this, and now I know what the LOWEST possible standard for a tuning app is. In fact screaming the word “TUNE!” at your bikes ECM will do a better job than this piece of junk. Don’t even waste your time. Trust me. Negative stars. ### 1/5 — Junk *2026-04-15* One of the worst tunes I’ve ever used. This tune caused my bike not to start and now I have to tow it to the dealer and hope it doesn’t cost me a fortune. I will definitely use Vance and Hines in the future. Never had an issue with it ### 1/5 — Trash, and no help from the MoCo *2026-04-10* Live tune works ok. Good luck getting one to actually download though. Good luck viewing your codes. Every time I try, I get an error message and the app crashes. Tried calling the MoVo and got a robot. FIX THIS TRASH, HARLEY. ## Most praised reviews (10 highest-rated) ### 5/5 — Decent app *2026-06-06* 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. ### 5/5 — Solid app *2026-05-27* Works as intended but not dumb people friendly ### 5/5 — Great App *2026-02-02, version 1.1.11* This works really well for my bike ### 5/5 — Fast! *2025-10-15, version 1.1.10* Had my tuner professionally installed I highly recommend that Cowboy Harley Davidson of Austin knocked it out of the park, super clean and crisp more power off the bottom quicker to get into the higher RPMs cleaned up the overall performance of the bike tremendously if I could give it seven stars I would ### 5/5 — Worked Well *2025-08-13, version 1.1.9* I would recommend ### 5/5 — Don’t know what all the fuss is about. *2025-05-13, version 1.1.8* I just purchased this Tuner & downloaded a new Stage 1 MAP for my 2025 Harley Fat Boy with No Issues At All. It couldn’t be easier. ### 5/5 — Works great *2025-04-10, version 1.1.8* I can’t speak for anyone else, but it worked first try with 0 issues for me. 2024 FXBBS ### 5/5 — Great product *2025-03-23, version 1.1.8* Tuner worked flawlessly as shown in the video. Went into the bike and removed my phone and then removed bike from phone as well. Did not use WiFi. Cellular data worked great. Put bike on 5 amp tender. Set fob and phone on the seat. Took less than 15 minutes to install stage 2 ### 5/5 — It's a dyno while you ride *2024-09-08* While I admit there is a serious learning curve involved, if you have patience, you will be pleased with the result. Currently I'm experimenting with a 24 FLTRX 117 with aftermarket 2into1 no CAT and the pipes were starting to blue even tho it seemed to be running fine. After adding the tuner and wideband O2 sensors I'm actually amazed by what this app can do. You can take multiple recordings and apply as many as you want over the base tune each time refining your tune. ### 5/5 — Pro street tuner *2024-06-22, version 1.1.5* I have the little tuner. It requires windows 10 or higher. I’m having trouble getting the latest app update to update. When I started the update, it says loading and never seems to load. What do I do to get the app to update the to the new version? --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
