Product Overview

Thundermax requires the use of an exhaust system with 18mm sensor bungs. Head pipes must be modified to accept 18mm sensors if they don't already.The ThunderMax ECM with Auto-Tune module mounts conveniently in place of the factory ECM and plugs in to the existing harness.

It utilizes wide-band O2 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.

Installation is easy. Simply replace the factory ECM, install new O2 sensors and harness, load the correct map for your bike, and ride!

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.

The ThunderMax ECM Improves throttle response, exhaust sound, and driveability.

Does not require dyno tuning!

Rider can adjust idle speed, rev limit and speedometer calibration.

Has 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.

Software program allows live monitoring, recording and examination of diagnostic codes and datalogs including number of starts, engine temperature and rpm operation.

Note: Because of possible clearance issues, some aftermarket exhaust systems may require modifications or relocation of their O2 sensor port bungs.
