Bully Dog ECM Tuner for CAT

The Bully Dog ECM Tuner is built with simple, easy-to-use performance in mind. This powerful device comes preloaded with the same high performance, dyno-proven tunes as our gauge tuners, except it is designed to be stowed away after installation–simply set it and forget it. The ECM Tuner is able to read and clear diagnostic trouble codes and is equipped with fully customizable Speed Limiter adjustments. Select between 3 preloaded tunes that increase horsepower, torque, and fuel economy, giving your rig the ability to tackle any challenge along the route. Cruise Limiter Increase and decrease the set limit of the vehicles cruise control. Very useful if continually crossing the US-Canadian boarder to change the cruise control set limit. Idle Shutdown Timer Set the length of time the vehicle will idle until the engine turns off. Great feature to save fuel to stop continous idling and extend the life of the turbo by allowing it to cool down before the engine shuts off. Speed Limiter Change the top speed that the vehicle will reach before the engine automatically limits the power needed to go faster.
