To answer your question simply…yes!
Now for the details. The 2012 Mustang
Boss 302 TracKey, developed as a joint project between Mustang engineers and Ford Racing, adds a second set of powertrain control module (PCM) software instructions to a Mustang Boss 302. Activated by a specially programmed vehicle key (Red Key), the new TracMode software alters more than 200 engine management parameters, increasing low-end torque and turning the potent but well-mannered stock Boss into a competition-ready 444 horsepower track car. Start a Boss 302 with the standard key (Black Key), and all factory engine settings are restored for a comfortable drive home from the course.
TracKey PCM software adjusts variable cam timing, spark maps, engine braking, fuel control and other engine parameters, more than 200 in total, to provide a complete race car calibration. The result is an aggressive, race-bred driving experience all the way down to the lopey idle rumbling through the Boss quad exhaust. When TracKey is removed and the vehicle is started with the standard key, the PCM settings are automatically drawn from the factory Boss 302 instruction set again without any additional modifications needed.
TracKey is now available for purchase and installation only at your Ford or Lincoln dealer. TracKey engine performance software upload is solely for the 2012 Boss 302
and Boss 302 Laguna Seca and is not compatible with any other vehicle. As an aftermarket product, TracKey comes with a "best-in-the-aftermarket" 3-year/36,000-mile warranty, and its installation and usage does not void the original OE warranty.
