Ultimate Tunability: 16 Selectable Advance Curves

The factory ignition timing is often a compromise designed for emissions rather than power. The Dynatek TC88 changes the game with 16 built-in advance curves, organized into four groups to suit different engine states and fuel grades. These curves allow you to optimize torque and horsepower while eliminating the engine “pinging” or detonation often caused by modern low-octane fuels. With simple rotary switches, you can dial in the perfect timing for your specific riding style.

8-Stage Adjustable Rev Limiter

Protecting your valvetrain is critical when pushing a performance V-Twin. The TC88 features an integrated rev limiter with 8 selectable positions, ranging from a conservative 5,750 RPM to a high-performance 7,250 RPM. This allows you to set a safety ceiling that matches your engine’s breathing capabilities and internal component strength, ensuring you don’t over-rev during aggressive gear changes.

Seamless Plug-and-Play Installation

There is no need for wire cutting or complex soldering. The TC88 is a direct “plug-and-play” replacement for the stock Harley module. It utilizes the factory 12-pin connector and works in harmony with the original sensors, including the MAP sensor and Crank Position Sensor (CPS). This ensures a clean, professional installation that maintains the integrity of your motorcycle’s wiring harness while providing a significant boost in electrical efficiency.

High-Energy Spark & Intelligent Starting

The TC88 is engineered to deliver a higher energy spark than the OEM unit, leading to more complete combustion, cleaner spark plugs, and smoother idling. Additionally, the module features an intelligent starting algorithm that ensures the engine is spinning at the correct speed before firing, which significantly reduces the strain on your starter motor and prevents the violent “kick-back” common in large V-Twins.
