ECU flashing is about to get a whole lot easier! 📲
Smartphone-based ECU flashing is in the final stages of testing to ensure a smooth workflow for release. This week we had successfully tested with the 13+ CBR600RR. Last week we tested the mini moto lineup — CRF110/125, Grom, Monkey, Dax all with great results. Additonal models like the CB/CBR/Rebel 300/500/650/750/1000 and SXS lineups are soon to follow.
With the new hardware/software you’ll be able to:
• Flash CJR tunes directly from your phone and switch between available maps (different fuels, engine braking, elevation, modifications, etc.)
• Receive new & revised tunes remotely, with a notification when a new tune is ready for you to flash
• Revert back to the stock file at any time
• Read & clear fault codes with option to send the error log directly to CJR for review
• View live engine data right from your smartphone dash
• Datalog your bike — add an optional wideband controller + O2 sensor + AFR Gauge kit to record your data, and send the logs through the cloud directly back to CJR for review and additonal custom refinement.
• Flash other supported Honda models or even a friend’s ECU using the same controller. (req. additonal license to flash via smartphone)
Best of all — less downtime. No mailing your ECU back and forth and no laptop required.
We’re currently working through final testing, file validation, datalogging, transferring our massive tune database, and ensuring compatibility across the Honda Powersports lineup is perfect upon full release.
