742038 Complete Kits Include Tcfi Plug in Fuel Injection Controller

The Daytona Twin Tec TCFI is a high-performance replacement for your stock ECM, offering real-time continuous auto-tuning for Dyna, Softail, and Touring models. Unlike standard tuners, it utilizes advanced Alpha-N fuel control, which eliminates the reliance on manifold pressure—making it the perfect choice for engines running aggressive, high-overlap camshafts. It gives you full control over ignition timing and advance curves, plus programmable outputs for shift lights or nitrous systems. The system supports all factory sensors, including security modules, and features built-in data logging for up to two hours of riding. With the included PC Link software, you can easily edit fuel maps in a spreadsheet format or view them in 3D to fine-tune your V-twin's performance.
