741717 Fits 2012 2015 Softail and 2012 2017 Dyna with Throttle by C

The Zodiac TOP Fuel Injection tuner is an essential performance upgrade for fuel-injected Dyna and Softail models. This load-based module is far more effective than simple throttle-position tuners because it senses the engine's actual load at any RPM, delivering the precise amount of fuel needed for peak performance. It comes pre-loaded with base maps that can be easily fine-tuned using a three-button interface, so you won't need a computer or a dyno to get your bike dialed in. Installation is completely plug-and-play with no wire splicing or permanent modifications to your harness. It is highly recommended for any bike running a performance exhaust or high-flow air cleaner, as it ensures your engine stays properly fueled for better throttle response and overall power.
