• Includes ECM with integrated auto-tune module, plug-in harness, two wide-band oxygen sensors, TMax software and USB communication cable.
• Hundreds of downloadable maps for different models, engine sizes, exhausts and cam combinations; load a map and let the integral auto-tune refine the air/fuel ratio in closed loop.
• Live monitoring, datalogging and diagnostics including number of starts, engine temperature and RPM.
• Adjustable AFR and ignition timing maps, startup maps, idle speed, rev limit and speedometer calibration; supports forced induction and nitrous setups.
• Easy installation: replace the factory ECM, fit the oxygen sensors and harness, load the correct map, and ride—no dyno tuning required.
• Free online map downloads, software and firmware updates, map analysis and technical support.

Includes mini USB pigtail. Because some aftermarket exhaust systems may have clearance issues, certain bungs or sensor locations could require modification or relocation—verify fitment before installation.
