Fiesta ST Cobb AP T1 Custom Tune Package
Crank up the performance of your Fiesta ST with a Cobb Accessport and Tunewerks T1 custom tune package! The Accessport is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your Ford. The in-cabin mountable Accessport V3 has a large, full color, high resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up race, street, or dyno gauge clusters), and mounting options. Together, with our FULLY optimized and dialed in ECU calibration for the Cobb AP, this combination will completely transform your Fiesta ST. Nothing will surpass custom tuning when it comes to increasing the output of your turbocharged hot hatch! This is the last engine management solution you'll ever need. With high quality fuel you can expect average peak to peak gains of 25+ WHP and 60+ WTQ compared to the stock ECU calibration.
Our test vehicle gained 35 horsepower and 84 ft. lbs. of torque AT THE WHEELS, as seen in the dyno chart. Off peak gains are just as impressive with a 51 WHP increase at 3500 RPMs and 41 WHP at 6000 RPMs!
PRO TIP: For even greater gains select 100 octane, E30, or E40 fuel options when placing your order. Just be sure you have access to the chosen fuel. Using the incorrect fuel with a purpose built ECU calibration can lead to serious engine damage!
Fiesta ST custom tuning and optimized ECU calibrations from Tunewerks are built to your specifications based on vehicle modifications, octane, elevation, environment, and preferences. We go beyond the standard OTS files included with the Cobb Accessport, tapping into our 18+ years of Ford ECU calibration experience, taking full advantage of your vehicle’s modifications and potential. Engine performance is optimized by reviewing data logging files along with program revisions and feedback from the end user in real world driving scenarios.
There are reasons why rally teams such as Team O'Neil Motorsports, LaRoza Racing, O.D.D. Racing, CBKB Rally Team, and Hovinga Motorsports have repeatedly used custom tune services by our calibration staff... Experience. Dedication. Championships.
Our goal is to deliver the safest, most reliable power available, but we are equipped to push the envelope for those who are after the very highest output achievable. Conversely, we are able to accommodate those who prefer to have something more conservative, as well.

The custom calibration and file revision period is 60 days from the time the first ECU calibration file is sent to the customer. Once the 60 day period has expired the custom calibration period ends. Future custom ECU calibrations are subject to additional fees depending on the exact nature of the request.
PRO TIP: When increasing boost pressure and overall performance of your Fiesta ST, ensure the spark plug gap is properly set. We recommend 0.025" gap to avoid misfires.
