742347 Fits 2016 2017 Softail

The Zodiac Top Fuel Injection tuner offers an easy way to optimize the performance of your fuel-injected Softail. This load-based tuner is designed for a simple installation with no wire splicing required. It arrives pre-programmed with base maps, allowing you to fine-tune the delivery with three buttons, making it even simpler than adjusting a carburetor. Because it senses the engine load rather than just throttle position, it provides much more accurate fueling across different riding conditions and speeds. This leads to smoother power delivery and better overall performance. While it works great on stock Softails, it is a vital addition if you have upgraded your intake or exhaust components to prevent lean conditions.
