ThunderMax Engine Control Module Kit with Integral Auto Tune - '18-'20 Softail

The ThunderMax 309-589 Engine Control Module Kit is designed specifically for Harley-Davidson Softail models from 2018 to 2020, providing advanced tuning capabilities for enhanced performance and drivability. This comprehensive kit includes the ThunderMax ECM with Auto-Tune module, a plug-in harness, two wide-band oxygen sensors, TMax software, and a communication USB cable. The system mounts easily in place of the factory ECM, ensuring a straightforward installation process that involves replacing the original ECM, installing new oxygen sensors, and loading the appropriate map for your bike. Once installed, the integral auto-tune feature automatically adjusts the air/fuel ratio for optimal performance across all riding conditions, eliminating the need for dyno tuning. The software allows live monitoring, recording diagnostic codes, engine temperature, RPM, and other data logs, enabling riders and technicians to fine-tune settings for specific performance needs. The ThunderMax ECM is compatible with a variety of exhaust systems and high-performance camshafts, supporting turbo, nitrous, and supercharger applications. Riders can customize ignition timing, idle speed, rev limit, and speedometer calibration, providing a tailored riding experience. The system is built in the USA and offers continuous updates, including new maps, firmware, and software enhancements, all accessible at no charge. Hundreds of downloadable maps are available based on modifications such as engine size, exhaust, air cleaner, pistons, and cams, allowing for precise tuning tailored to individual bikes. Features include adjustable AFR maps for front and rear cylinders, ignition timing maps, and startup maps, ensuring comprehensive control over engine parameters. This kit enhances throttle response, exhaust sound, and overall driveability, making it an ideal upgrade for riders seeking maximum performance without the need for professional dyno tuning.
