ThunderMax Fuel Tuner for 2004-2013 Harley-Davidson
Looking for a do-it-all tuner? The ThunderMax is innovative because it's not a traditional tuner—it's a complete ECM!
- Kit includes
- ThunderMax ECM with Auto-Tune Module
- Plug-and-play harnesses
- Two wideband oxygen sensors
- ThunderMax software and communication USB cable
- Instructions
- Can benefit from dyno tuning, but it's not required if you choose to allow your ThunderMax to "learn" the correct settings your specific motorcycle wants after choosing the correct base map
- Hundreds of maps available for various models, engine sizes, exhaust systems, air cleaners, pistons, and cams
- Software allows live monitoring, recording and examination of diagnostic trouble codes and data logs including number of starts, engine temperature and rpm operation
- Utilizes wideband oxygen sensors to continuously self-adjust and properly tune the motorcycle's air/fuel ratio
- ThunderMax ECM with Auto-Tune module mounts conveniently in place of the factory ECM and plugs in to the existing harness
- New maps, software, firmware updates, map analysis and tech support available online at no charge
- Works with all popular exhaust systems and is compatible with high-performance camshafts
- Adjust idle speed, rev limit, and speedometer calibration
- Improves throttle response, exhaust sound and driveability
- Supports forced induction applications
- Made in the USA
- Some aftermarket exhaust systems may require modification or relocation of the oxygen sensor port bungs
ThunderMax tunes on-the-fly, just like an OE vehicle; "closed loop" here means that it adjusts and reacts to your bike's performance in real time, continuously reading and adjusting air/fuel ratio in real time.
Fueling points are mapped every 1-1/2° of throttle and every 256 RPM. Because of this, the ThunderMax system delivers unmatched precision for smooth, consistent performance in most riding conditions. A built-in barometric sensor accounts for altitude and ambient air changes automatically—just load the map that matches your build and ride.
