AREAS WE ADDRESS

Fuel tables are tuned to optimize either fuel economy or peak performance, depending on the specific goals of the vehicle owner. In the case of the Ford Focus ST 2.0L EcoBoost, we’ve found that the factory fueling tables are set quite conservatively, with extended delay timers and throttle position delays before additional fuel is injected. These long fuel delays can limit improvements in power and torque. While some fueling delays are beneficial for maintaining better fuel economy, reducing these delays can unlock significant performance gains, allowing the engine to respond more dynamically and efficiently when more power is needed. We tailor the fuel table adjustments to suit your desired balance of economy and performance.

The Focus ST, particularly with its Drive-by-Wire (DBW) system, often suffers from poor throttle response both at low RPMs and on the top end. This can create a noticeable lag or unresponsive feel when you step on the gas pedal. The DBW system works by managing torque output from the engine to the wheels based on pedal position, essentially acting as a torque limiter—it only allows a certain amount of torque for each level of throttle input. The stock settings are often overly conservative, resulting in a numb or delayed pedal response.

Correcting this issue is crucial for significantly enhancing throttle response, giving you a more immediate and dynamic reaction when pressing the pedal. By reworking the OEM DBW strategies, we unlock smoother power delivery, transforming the way the car feels when accelerating. This adjustment is one of the most important changes for unleashing more torque, horsepower, and overall driving enjoyment, making your Focus ST feel truly responsive and alive.

To unlock the full potential of your vehicle, we focus on three main types of limiters: Engine Torque Limits, Transmission Torque Limits, and RPM Limits. These limiters control the amount of power the vehicle can send to the wheels, ensuring it performs within safe operational parameters. By adjusting these limits, we help the vehicle deliver its true performance capabilities, giving you more power and responsiveness without pushing it beyond its capabilities.

We make these adjustments carefully, preserving the factory fail-safes to maintain reliability and safety. For those who prefer to keep the factory settings in place, we can leave the original limiters as Ford has set them, based on customer preferences. Whether you want maximum performance or a more conservative approach, we can tailor the vehicle’s limits to match your driving needs.

By increasing the RPM limits in key areas, we can significantly improve both torque and horsepower, optimizing the engine’s power output across a wider range of driving conditions. This allows for smoother acceleration and a more responsive driving experience. Additionally, using higher-octane fuel enables more aggressive timing and spark advancements, which can further boost both power and fuel economy. The higher octane allows the engine to run more efficiently, taking advantage of the additional timing adjustments to extract more performance while maintaining reliability. Together, these modifications create a balanced increase in both power and efficiency for an overall better driving experience.

We offer the following tunes for the 2013-2018 Focus ST:

85 Performance, 86 Performance, 87 Performance, 88 Performance, 89 Performance, 90 Performance, 91 Performance, 92 Performance, 93 Performance, 94 Performance – These likely refer to performance tunes tailored for different fuel octane levels, typically 85-94. Each number corresponds to the specific octane rating, with higher numbers often leading to better performance and the ability to run more aggressive timing and boost.

e30 Performance, e50 Performance, e85 Performance*** – These tunes are for vehicles running on ethanol-based fuels like E30, E50, and E85. These fuels offer higher octane levels and can lead to improved performance, especially in terms of horsepower and torque. These specific tunes are designed to optimize the vehicle’s setup for ethanol blends.

Boostane Performance – This refers to a performance tune designed to work with Boostane, a fuel additive that boosts the octane rating of the fuel, enabling the engine to run more aggressive timing for added performance.

85+ Economy – This tune is focused on achieving better fuel economy while using an E85 blend or higher ethanol content, offering a balance between performance and fuel efficiency.
