A programming handset from Ford Racing offers a perfect example of tuning possibilities. For the Focus ST's 2.0-litre EcoBoost engine and the Fiesta ST's 1.6-litre EcoBoost, Ford Racing offers ProCal, which any performance enthusiast can purchase at FordRacing.com for $595.
With the device plugged into the car's diagnostic link connector port in the driver's side footwell, the many aspects of the car's performance can be tapped into - 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 122Nm increase in torque - all while maintaining the Ford-backed limited warranty.
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 maximise the performance of Ford vehicles.
