Highly advanced, stand-alone tuning system utilizes proprietary Autotune technology with wide-band oxygen sensors to deliver unmatched performance and rideability
Comes 100% assembled, ready to install with no wire-cutting or splicing required
Every degree and a half of throttle; every 256 RPM, there is a fueling point that is automatically adjusted
Simply replace the factory ECM and oxygen sensors, load a map, and enjoy your new ride!
More control and a smoother running engine with built in barometric sensor you never have to think about ambient air changes
WideBand oxygen 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
Fully adjustable with our Thunder Max tuning software or can be used just by loading a base map
