Comes completely assembled and ready to install, no wire cutting or splicing required. Purchase once and all software, firmware and an extensive library of base maps for 88" to 131" are free, allowing the system to grow with future bike modifications without future tuning expenses. No DYNO required--ThunderMax with Autotune continually tunes how you ride, where your ride, every time you ride. ThunderMax provides more power, increased torque, better sounding exhaust and quicker throttle response while optimizing your bikes power output by tuning for your riding style, riding conditions and exhaust system. Your bike will run smoother and considerably cooler by continually maintaining the correct AFR and adjusting the base map as you ride with immediate real time feedback. Allows advanced users and professionals the ability to control every parameter of the system for custom tuning, if required. ThunderMax is a complete factory replacement and is not a Flash Tuner or in-line signal modifier. Utilizes wide band 18mm O2 sensors for real time AFR analysis and correction at all RPM's and load levels. Operates as a closed loop control system to continuously self-adjust and properly tune the motorcycles air fuel ratio for all riding conditions. Designed to fit in the same location as the factory ECM--simply remove factory ECM and install. ThunderMax, plug into existing harness, change the O2 sensors, load the correct base map from TMAX Tuner software and enjoy your ride.
