The ThunderMax with AutoTune System is a fuel-management system representing the future in smart aftermarket components for H-D motorcycles. Developed by Zipper's Performance Products and Thunder Heart Performance, ThunderMax incorporates the same technology used on high-performance racecars and applies it to V-twin engines.
The ThunderMax with AutoTune system consists of the ThunderMax Electronic Control Module (ECM) and the AutoTune. The system works by constantly monitoring air/fuel ratios, and instantly adapting for changes in ambient riding conditions such as: air pressure, air temperature, elevation, and air density. The key to the system is starting with the dyno-developed base maps, then allowing the system to learn.
The library of base maps is continually growing and covers a wide range of applications, with maps available for all fuel-injected Harley-Davidsons and most popular aftermarket parts combinations. Using the parameters set by the base map loaded into the ThunderMax ECM, the AutoTune then fine-tunes the map at every throttle position customizing the base map for the rider and his riding conditions.
The average Joe can install the unit, set the base map, and go for a ride. You don't have to be a rocket scientist to use the ThunderMax and get the best tune for your bike. However, someone with more advanced tuning needs, like a tuner or a racer, can use the provided ThunderMax Tuner Software to tailor the fuel system to his needs. This includes, but is not limited to, starting, idle speed, fuel, spark, and rpm.
The system is completely adaptable to the changes that riders make to their bikes, and even to custom applications. Whether the changes are simple like air cleaners, exhaust pipes and cams, or are more complex, performance-oriented upgrades like big-inch motor kits, the ThunderMax can grow and adapt. The ThunderMax provides a more stable engine operating temperature and a reliable fuel delivery platform, allowing any rider from street to strip to achieve his or her performance goals.
