From ThunderMax website:

"Note: ThunderMax 309-485 uses ECM case marked 309-460, but the kit is supplied with a pigtail harness and a 90-degree USB linking cable for added installation flexibility. Includes ThunderMax ECM with Auto-Tune Module, plug-in harness and two wide-band sensors, TMax software and communication USB cable, Quick-Start Easy Install and Comprehensive User's Manual, technical support and free software and updates. Hundreds of maps available to download for your bike (based on model, engine size, exhaust system air cleaner, pistons, cams, etc.) - load the map of your choice and the integral auto-tune will do the rest. Software program allows live monitoring, recording and examination of diagnostic codes and datalogs including number of starts, engine temperature and rpm operation. Utilizes wide-band oxygen sensors and works as a closed-loop control system to continuously self-adjust and properly tune the motorcycle's air/fuel ratio for all riding conditions. ThunderMax ECM with Auto-Tune module mounts conveniently in place of the factory ECM and plugs in to the existing harness. Easy installation: replace the factory ECM, install new oxygen sensors and harness, load the correct map for your bike, and ride. New maps, software, firmware updates, map analysis and tech support available online at no charge. Adjustable front and rear cylinder AFR maps, ignition timing (spark) maps, and startup maps. Works with all popular exhaust systems and is compatible with high-performance camshafts. Rider can adjust idle speed, rev limit and speedometer calibration. Improves throttle response, exhaust sound and driveability. Supports turbo, nitrous and supercharger applications. Does not require dyno tuning. Made in the USA Because of possible clearance issues, some aftermarket exhaust systems may require modifications or relocation of their oxygen sensor port bungs. Includes mini USB pigtail."

Fits 2010-2013 Sportster models ONLY. Message us with VIN number beforehand and we will double check fitment. Sales will not be processed without VIN check.
