MY22+ | ECU Tuning | Honda NX500 / CB500X / CB500F

Product Overview:

The NX500/CB500 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 improvements in both power output and drivability. On off throttle characteristics have been refined to a smoother takeoff and low speed drivability.

This tuning series is optimized for 87 octane (R+M)/2 (91RON) fuel and supports 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 and stock airbox but still allowing support for aftermarket air filters
• Stage 0.5: Requires the 550Performance PowerFlow Intake System
• Stage 1.0: Designed for a full exhaust system in conjunction with the PowerFlow Intake System

Both primary and secondary fuel maps have been meticulously revised and calibrated to ensure continued operation in the event of critical system sensor failures. For instance, if the TPS sensor fails, the bike will maintain operational integrity without significant degradation in performance.

550Performance LLC provides free tune updates for existing NX500/CB500 tune customers. If you initially purchase the Stock Improved tune and later upgrade to a full exhaust system, we will update your ECU at no additional cost—customers are only responsible for shipping and handling fees.

Technical Features:

• Engine Speed Limiter: 9000 - 10500 RPM, depending on tune
• Ignition Timing: Revised tables optimized for maximum power and drivability
• Primary Fuel Mapping: Calibrated for peak power output
