MY19+ CRF450RL | ECU Tuning

Product Overview:  The CRF450L/RL Tune Series delivers a comprehensive suite of calibrations for the factory ECU, tailored to various hardware configurations. Regardless of the specific setup, users can anticipate substantial improvements in both power output and drivability. Notably, low-speed drivability has been significantly enhanced compared to the stock configuration. The rider-experienced physical jerk (measured in G/s) has been rigorously characterized and reduced by nearly 50%. Additionally, the fuel cut, which contributes to abrupt deceleration (negative jerk), has been eliminated, virtually eradicating flame-out events. This tuning series is optimized for 91 octane (R+M)/2 (95 RON) fuel and supports typical airbox modifications and common aftermarket air filters. The series is segmented into three distinct tunes based on exhaust hardware configurations: Stock Improved: Compatible with the stock exhaust system, with support for modifications to the existing setup.
