No doubt, the 2012 Ford Mustang Boss 302 is a special kind of car. Blurring the lines between race car and street car, it is poised to uphold the heritage of the original Boss. And today, Ford announced perhaps one of the coolest features the new Boss has - a special secondary key that "unlocks" a race mode.
The key, called a "TracKey" actually activates a secondary PCM race tune that changes nearly 200 engine management parameters for the 5.0. Jeff Seaman, Mustang powertrain engineer, explains it best. "It's not for use on the street – for example, the deceleration is set up to preserve the brakes, and the throttle response is very aggressive. A skilled driver on a closed course will really appreciate the benefits."
The TracKey also features a two stage launch control which can be controlled through buttons on the steering wheel, for those wanting a little drag race action.
And what better time to test out these cool electronic toys than with a complimentary track day? Ford will be offering just that to those who purchase a 2012 Boss. Owners will be treated to driving instructions and track time at Miller Motorsports Park in Tooele, UT.
Press ReleaseDEARBORN, Mich., Nov. 11, 2010 – You hold two keys: One has a black Boss logo, the other red: Either will start your 2012 Mustang Boss 302. Slide the all-black key into the lock cylinder, give it a twist and you're treated to 444 ponies worth of smooth, streetable driving joy. Or choose red – the TracKey – and you have a competition-ready track car.
A joint project between Mustang engineers and Ford Racing, TracKey adds a second set of powertrain control module (PCM) software to a customer's Mustang Boss 302, activated by a specially programmed vehicle key. When invoked by TracKey, 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 track car. Remove TracKey and start Boss with the standard key, and all factory engine settings are restored for a comfortable drive home from the course.
"From an engine management standpoint, we've done just about everything possible to give TracKey users a full race car experience," explains Jeff Seaman, Mustang powertrain engineer. "It's not for use on the street – for example, the deceleration is set up to preserve the brakes, and the throttle response is very aggressive. A skilled driver on a closed course will really appreciate the benefits."
As part of the TracKey software package, Ford engineers also devised a two-stage launch control feature similar to that used on the Cobra Jet race car. Using a combination of steering wheel buttons, drivers can set the tach needle to a desired launch rpm. Floor the throttle and the engine will rev to the preset rpm until the clutch is released, helping aid acceleration and vehicle control from a standing start.
One key, hundreds of changes
Devised during an all-night garage brainstorming session among core Mustang team members, TracKey introduces the concept known as the dual-path powertrain control module. The industry-first, patent-pending innovation allows two separate sets of engine management software to exist on a single PCM, selected through the existing SecuriLock® Passive Anti-Theft System (PATS) transceiver found in current production keys.
The TracKey PCM software, installed by an authorized Ford dealer after a customer takes delivery of the car, 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.
"Anything that could possibly affect all-out performance is deleted from the TracKey calibration," said Dave Pericak, Mustang chief engineer. "Throttle limiting and torque management – any daily driveability enhancements are removed and replaced with a pure Ford Racing competition calibration."
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 – a huge advantage over aftermarket tuning chips and ECU reprogramming. The convenience is useful for enthusiasts who want all-out performance at the racetrack but stock driveability for the journey there and back.
An after-hours obsession
In the early stages of TracKey development, a major challenge was the complexity of installing multiple PCM computers and switching between them. However, Ford controls engineers developed a method to choose between two unique sets of software in a single powertrain control module on the Boss 302: The dual-path PCM was born.
"We installed the 302R software on the same PCM that held the stock Boss software," says Seaman. "Then the controls engineers developed a software system to activate one or the other, depending upon which key was used to start the vehicle. Really, all the parts to make this work existed – the Ford MyKey® system was already using the PATS transceiver to perform specific actions based on the key used to start the car, and the PCM was flexible enough to handle multiple control modules. It was just putting everything together."
As the project unfolded, the team was driven by the uniqueness of what they were trying to accomplish, and TracKey became an obsession. Considering the compressed time frame in which the technology was developed, motivation was essential to the creation of the finished product.
"We've all been really excited about TracKey, so it came together quickly," explained Pericak. "The concept was first discussed in spring 2009, and here we are 18 months later with a finished, tested, verified product. It's a perfect example of what can happen when you get a core, cross-functional team willing to contribute 24/7 to bring a great idea to life."
TracKey powertrain software installation and key programming will be available to 2012 Mustang Boss 302 owners through Ford Racing authorized dealers. Pricing will be announced at a later date.
DEARBORN, Mich., Nov. 11, 2010 – Buyers of Ford's highly anticipated Mustang Boss 302 will now get a hands-on track driving experience to learn just what their car is capable of as part of a new complimentary program being announced today.
"The Mustang Boss 302 is a very special vehicle, tuned to perform on a racetrack," said Mickey Matus, marketing manager, Ford Racing. "It's an absolute blast to drive on the street but we want owners to be able to experience all the incredible balance, power and performance engineered into this machine, and the only safe way to do that is to push the car to the limit on a closed course. This is only natural, since the Boss grew up on the racetrack."
The Boss Track Attack program, offered through Team Mustang and Ford Racing, will feature a full Boss immersion, driving instruction and plenty of track time with engineers and racers. The experience is designed to give Boss owners a comprehensive, hands-on look at exactly what their cars are capable of – and just how much fun they can be.
Boss Track Attack will take place at Miller Motorsports Park in Tooele, Utah, outside of Salt Lake City. Boss owners will need to make their own travel and lodging arrangements, but once in Utah, the full track experience – including cars for the event – is courtesy of Ford.
The evening before the track day, owners will be treated to a welcome reception followed by an in-depth immersion into both the non-product and product stories of the Boss 302, focusing on how the program came to be and the underlying engineering and design philosophy. The next morning, participants will convene at the track for a full day of driving instruction and course time.
"Practice makes perfect, and in this case it's going to be a ton of fun, too," said Jamie Allison, director, Ford Racing. "There's nothing like the experience of being behind the wheel of a high-performance car on a dedicated track. It's the environment that breeds incredible machines like Mustang Boss, and for owners who want to experience all these cars are capable of, we can promise an unforgettable event."
More details about Track Attack, including dates, will be available in early 2011.
