Description

Every degree and a half of throttle; every 256 RPM, there is a fueling point that is automatically adjusted. That means more control and a smoother running engine. With the built in barometric sensor you never have to think about ambient air changes. WideBand O2 sensors constantly read the Air Fuel Ratio and give live, real time feedback to the ECM. That means, no “accepting” the changes made to the map, once you key off the changes are written. The ThunderMax ECM is fully adjustable with our ThunderMax tuning software or can be used just by loading a basemap. The choice is yours.

This product is intended for “RACE READY” vehicles only and is not for sale or use on vehicles otherwise subject to emission control requirements.  In the state of California, this product should not be used on any vehicle that is registered for use on public roads.
