We've partnered with the wizard at 550 Performance to offer a custom tune to match our 301cc big-bore kit with supporting mods.

This flashed ECU is required when running the the big-bore kit and is set up to work with an aftermarket exhaust, CBR300R camshafts, vented airbox lid, and CBR300R velocity stack. A hi-flow air filter is optional. 

This tune is more than just a fuel map. Here are some of the key features:

  • Engine speed limiter set to 11,000 RPM
  • Warm idle speed adjusted to 1,500 RPM
  • Refined ignition timing tables tailored for 91 (R+M)/2 (95 RON) octane fuel
  • Primary fuel tables fine-tuned for peak power output
  • Secondary fuel tables optimized for component protection
  • Elimination of check engine lights related to the EVAP and PAIR systems
  • Deceleration fuel cut adjusted to improve on/off throttle sensitivity
