2015 Ford Mustang customers looking to tweak their ponies have plenty of options as far as aftermarket parts and updates go, one of which is the Blue Oval’s very own Racing division. Ford Racing Parts has already launched a slew of upgrades for the sixth-generation Mustang, ranging from cat-back exhausts and mufflers, for both the EcoBoost and the GT, to halfshaft kits. More parts are scheduled to become available throughout 2015, but next year is also set to bring a custom engine calibrations for the four-cylinder ’Stang. That’s great news for enthusiasts who want to add more oomph to the EcoBoost’s 310 ponies and 320 pound-feet of torque without voiding the factory warranty.

Details are still scarce as of December 2014, but Ford Racing says the update will hit the market by the end of 2015. Also, the company has yet to release info about the amount of horsepower and torque it will add to the turbocharged four-pot, but mentioned that the Focus ST’s 2.0-liter EcoBoost will receive up to a 90-pound-feet increase in torque. With the hatchback set to have its torque increased by up to 30-percent, it’s safe to assume the same mod will enable the Mustang’s 2.3-liter unit to crank out more than 400 pound-feet. A power bump to around 400 ponies is also likely.

In addition to this upgrade, which customers will be able to load into the car’s ECU with a Ford Racing ProCal handset, Ford Racing also plans to roll out a number of parts and accessories dedicated to enthusiasts who are not concerned about maintaining their factory warranty. Details are slim in this department as well, but Ford Racing quotes packages showcased by Mountune and Full-Race Motorsports at the 2014 SEMA Show. The latter enables the 2.3-liter EcoBoost to churn 500 horsepower and 450 pound-feet, a massive 190-pony and 139-pound-feet improvement over the standard version. Excited yet?

Why it matters

Granted, throwing a bunch of beefed-up parts at the engine is a lot more exciting, but those massive gains that come with hotter intakes and cams can affect the car’s maneuverability unless other updates are applied. What Ford Racing plans to do is offer decent gains at affordable prices for drivers who want a few extra ponies without going elbows deep under the hood. This update not only maintains the Mustang’s factory warranty, but it’s also friendlier to customers who aren’t planning on using the extra oomph on a race track.

The 2.3-liter EcoBoost engine is brand-new for the Ford Mustang, having been introduced with the redesigned, sixth-generation pony. Slotted between the familiar 3.7-liter V-6 and the 5.0-liter V-8, the EcoBoost is the only Mustang unit to use forced induction and marks the four-cylinder’s return in the lineup since the third-generation pony was discontinued in 1993. The four-banger generates 310 horsepower at 5,500 rpm and 320 pound-feet of torque from 2,500 rpm. This output enables the Mustang to hit 60 mph from a standing start in about five seconds.

Transmission choices include a six-speed manual and a six-speed automatic with paddle shifters. EPA estimates for the manual version sit at 31 mpg highway, 22 mpg city and 26 mpg combined, making the EcoBoost the most fuel efficient 2015 Mustang. The EcoBoost model retails from $25,170, with the EcoBoost Premium trim fetching $29,170. The convertible model, which is only available in Premium trim, is priced from $34,670.

Ford’s award-winning EcoBoost® engine lineup not only has great EPA-estimated fuel economy ratings, it is also becoming a favorite family of engines in the performance tuning community.

From the infancy of the automobile, tinkerers have always chased more power by removing original components and replacing them with expensive aftermarket parts. This can lead to added performance, but at a cost to fuel efficiency, durability or driving comfort most owners would never accept.

For example, while replacing a camshaft can result in added horsepower, but typically a smooth idle must be sacrificed. Replacements can include new exhaust and intake manifolds, high-flow fueling systems and sometimes superchargers. This kind of tuning requires significant know-how and for the vehicle to be out of operation for some time.

Now, with the advent of computer-controlled engines, tuners have begun modifying a vehicle’s original programming for increased engine performance in the areas they choose. The technologies in Ford EcoBoost engines make their efforts even more effective.

Advanced EcoBoost technology includes direct injection, variable cam timing and turbocharging that, together, offer excellent power density and EPA-estimated fuel economy ratings straight from the factory. In the hands of engine tuning experts, tweaking these attributes can result in tremendous gains in horsepower and torque output, at an inexpensive price tag.

A programming handset from Ford Racing offers a perfect example of the tuning possibilities. For Focus ST’s 2.0-liter EcoBoost engine and Fiesta ST’s 1.6-liter EcoBoost, Ford Racing offers ProCal, which any performance enthusiast can purchase at FordRacing.com for $595. Plug the device into the car’s diagnostic link connector port in the driver’s side footwell to tap into the many aspects of the car’s performance – anything from throttle response characteristics or idle speed, to turbo wastegate control, to fuel curves and spark timing.

While these settings should be modified only within recommended limits, the resulting performance gains with Ford-tested programs can be impressive. Focus ST owners, for example, can expect up to a 90 lb.-ft. increase in torque – all while maintaining the Ford-backed limited warranty.

Ford Racing is developing custom engine calibrations for the all-new Mustang 2.3-liter EcoBoost, with a product expected on the market by the end of 2015.

Not all enthusiasts are concerned about maintaining their factory warranty, and for those Ford has committed to working with aftermarket tuning companies to enable the development of high-quality parts and accessories to maximize the performance of Ford vehicles. Aftermarket tuners have achieved impressive performance gains for the all-new 2.3-liter EcoBoost I-4 in the 2015 Ford Mustang. Several tuners, including Mountune and Full-Race Motorsports, showcased their modified EcoBoost Mustangs at the 2014 SEMA Show.

By working with respected turbocharging engine experts from around the world including Mountune and Full-Race Motorsports, Ford is demonstrating a commitment to a new breed of forced-induction performance. Expect to see more exciting new options from Ford Racing in the near future.
