Description

Description for ThunderMax ECM With AutoTune Closed Loop System

The ThunderMax ECM With AutoTune Closed Loop System is the high-tech way to manage motorcycle performance. It mounts conveniently in place of your factory ECM and plugs into your existing harness, and uses a closed-loop control system to continuously self-adjust and properly tune the motorcycle's air/fuel ratio for all riding conditions. The ThunderMax has hundreds of maps available to download for your bike. Choose based on model, engine size, exhaust system air cleaner, pistons, cams, and more. Then, load the map of your choice and the integral auto-tune will do the rest. You can adjust the idle speed, rev limit and speedometer calibration, front and rear cylinder AFR maps, ignition timing (spark) maps, and startup maps, all without dyno tuning. It works with all popular exhaust systems, is compatible with high-performance camshafts, and supports turbo, nitrous and supercharger applications. The software allows live monitoring, recording and examination of diagnostic codes and datalogs including number of starts, engine temperature and RPM operation. Easy installation and tech support, free software and updates included. 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. Will require the use of an exhaust system with 18mm sensor bungs or head pipes must be modified to accept 18mm sensors.

If you wanna make power, get a thunder max. If you plan on building your bike for power. Get a thundermax. Install is easy and there are plenty of youtube tutorials on how to set it up.

I did not realize it was 11 to 14 days for processing, I wish I ordered this from fuel moto for $799 instead of $899 fuel moto also will pre program it to your bike specifications before sending it so you can just plug it in and ride.
