723234 Fits Milwaukee Eight Softail 2018 2020

The ThunderMax EFI system with AutoTune is a self-tuning fuel management module for Softail, Touring, and Trike models. It runs a wide-band closed-loop setup that adjusts air-fuel ratio automatically as you ride. It compensates for fuel quality, altitude, and weather changes. You get smoother running, sharper throttle response, and easier starting on both stock and heavily modified bikes. It helps eliminate backfiring and lets you set a custom idle speed. You need exhaust pipes with 18mm O2 sensor bungs, or you must modify your current pipes to accept the sensors supplied in the kit.
