Funny to realize that trike owners erroneously think that what works for 2-wheel motorcycles will not necessarily work on their 3-wheelers…Regarding dramatically improving throttle response and overall performance, ThunderMax with AutoTune for Harley-Davidson® EFI Trike Models replaces the factory ECM with the user-friendly ThunderMax ECM.
Performance made simple: the included wide-band oxygen sensors provide real-time Air/Fuel Ratio feedback to ECM for automatic AFR corrections under all ambient conditions. Along with automatic AFR tuning, the ThunderMax allows the trike owner to simply adjust idle speed, rev limit, ignition timing, deceleration pop control, starting and acceleration pump fuel, speedometer calibration and more. The versatile ThunderMax allows live tuning, monitoring and recording, reads and logs diagnostic codes.
