I'll make sure I update it as soon as possible, hoping for a better experience and review of yours. You can send it to info@isorensen.com Thank you for your feedback, Eduardo ### 3/5 — Codes not listed *2024-11-02, version 1.6.0* 4 codes and all 4 not listed in database. P3733, P3802, P4302 and P4307 All ECM Codes on a 2022 Ultra Limited with V&H FP4. Is it possible that Vance & Hines have their own codes that can get recorded? ### 4/5 — Nice quick reference *2022-06-28, version 1.6.0* I’d like to see the codes for 2003-older bikes on the app. Granted, there’s not many codes for the older bikes and probably not many still riding the older models. But, it would be helpful to those of us still riding the old ones. If those could be added to the app….it would be great! ### 5/5 — Perfect for what i need *2024-11-15, version 1.6.0* This app is ideal. No personal data collected. No micro transactions. No over reach of permissions. Just lets me troubleshoot and work in my bikes. Thanks for publishing it. ### 5/5 — Great app *2023-01-17, version 1.6.0* After identifying a code, it is easy to look in a service manual, and fix the problem. ### 5/5 — Harley Codes *2020-03-08, version 1.3.1* Was on a bike trip got a check engine was able to find the code and was better informed when I talked to dealer regarding my issue this is a great app... --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
