THUNDERMAX ThunderMax Engine Control Module Kit with Integral Auto Tune — Black – 11 Softail, 11 CVO

The ThunderMax Engine Control Module Kit with Integral Auto Tune replaces the factory ECM to deliver precise air/fuel control, improved throttle response and better driveability.

• Includes ThunderMax ECM with integral Auto‑Tune module, plug‑in harness, two wide‑band oxygen sensors, TMax software and USB communication cable.
• Hundreds of downloadable maps for your bike — choose the map for your model, engine size, exhaust and cams, then let the integral auto‑tune refine the AFR.
• Software provides live monitoring, recording, diagnostic code review and datalogs including starts, engine temperature and RPM.
• Closed‑loop wide‑band sensor control continuously self‑adjusts fuel delivery for all riding conditions and supports turbo, nitrous and supercharger applications.

Installation is straightforward: replace the factory ECM, install the oxygen sensors and harness, load the correct map for your bike, and ride — no dyno required.

Adjustable front and rear AFR maps, ignition timing and startup maps allow fine tuning without external equipment.

New maps, software and firmware updates, map analysis and technical support are available online at no charge.

Made in the USA. Some aftermarket exhausts may require sensor bung relocation for clearance. 🏍️🔧
