The company suggests the EcoBoost engines have been factory tuned to balance fuel efficiency with power density, but existing technology — direct injection, variable cam timing and turbocharging — can easily be tweaked via software management as an inexpensive way to increase horsepower and torque output.
Ford Racing has already developed a programming handset for the Focus ST’s 2.0-liter EcoBoost engine, along with the Fiesta ST’s 1.6-liter EcoBoost mill. The ProCal tool, which costs $595, can be used to modify throttle response, idle speed, turbo wastegate control, 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,” the company said in a statement. “Focus ST owners, for example, can expect up to a 90 lb.-ft. increase in torque – all while maintaining the Ford-backed limited warranty.”
The Mustang’s 2.3-liter EcoBoost engine is naturally the next powerplant on the tuning list, with a product expected to arrive on the market by the end of next year.
