THUNDERMAX ThunderMax Engine Control Module Kit with Integral Auto Tune — Black – 02-17 VRSC, 05-07 CVO

This engine control module kit provides a plug‑in ECM replacement with an integral auto‑tune module for continuous, closed‑loop air/fuel control 🎯.

The kit includes the ECM with auto‑tune module, plug‑in harness, two wide‑band oxygen sensors, software and a USB communications cable for map loading and datalogging 📘.

Hundreds of downloadable maps are available for specific bike configurations so you can load the map that matches your engine, exhaust and intake, then let the integral auto‑tune do the rest 🔧.

Use the software to monitor live parameters, record and review datalogs, and examine diagnostic codes including start counts, engine temperature and rpm.

Adjustable AFR maps for front and rear cylinders, ignition timing maps and startup maps let you fine‑tune idle, rev limit and speedometer calibration; the system supports turbo, supercharger and nitrous applications 📈.

Installation is straightforward: replace the factory ECM, install the supplied oxygen sensors and harness, load the correct map for your bike and ride — dyno tuning is not required ⚙️.

New maps, software and firmware updates, map analysis and technical support are available online at no charge, and the product is made in the USA 🇺🇸.
