Key Features of ThunderMax ECM:

• AutoTune Technology for automatic fuel adjustments

Easy Installation: Plug-and-Play for Quick Setup

ThunderMax ECM is designed to be a plug-and-play upgrade for your EFI Harley Davidson®. It comes 100% pre-assembled, so you won’t need to cut or splice any wires. The installation process is simple and fast: just replace the factory ECM and oxygen sensors, load your map (or use the pre-loaded basemap), and you’re good to go!

Simple Installation Process:

1. Remove the factory ECM and oxygen sensors.
2. Install the ThunderMax ECM and wide-band O2 sensors.
3. Load the map you prefer, or use the pre-programmed basemap.
4. Start riding with smoother acceleration and enhanced power.

AutoTune Technology: Real-Time Fueling Adjustments

One of ThunderMax’s standout features is its AutoTune technology, which automatically adjusts the air-fuel ratio in real time, ensuring your bike always runs at optimal performance. ThunderMax automatically makes fueling adjustments at every 256 RPM and every degree-and-a-half of throttle to provide a smoother, more responsive engine.

How ThunderMax AutoTune Works:

• Wide-band O2 sensors constantly monitor the air-fuel ratio, providing continuous feedback to the ECM.
• Automatic fueling adjustments ensure consistent performance across all RPM ranges and throttle positions.
• Barometric sensor compensates for ambient air changes, so you never have to manually adjust for weather or altitude.

This dynamic fueling system means your Harley Davidson® will always deliver a smooth and powerful ride.

Fully Adjustable Tuning: Customize Your Ride

While ThunderMax ECM works perfectly with its pre-loaded basemap, it also offers complete adjustability with ThunderMax tuning software. This allows you to fine-tune your bike’s performance, giving you full control over everything from fueling to throttle response.

ThunderMax Tuning Options:

• ThunderMax tuning software allows for advanced adjustments to fueling, throttle response, and more.
