ZERONINE Design FLASHLink Cylinder Deactivation – Ford Fiesta ST Mk8/Mk8.5

09 Design FLASHlink Cylinder Deactivation – Ford Fiesta ST Mk8/8.5 Remove the odd VDE misfire tone and enjoy a smoother drive. This 09 Design calibration switches off the factory Variable Displacement Engine function that shuts one cylinder on light throttle in the 1.5 EcoBoost Dragon engine. It keeps all factory safety strategies in place and does not add power. Expect a cleaner, more consistent exhaust note and throttle feel, especially on cars with aftermarket exhausts. Fuel economy may reduce slightly in gentle driving. Designed for Ford Fiesta ST Mk8 and Mk8.5 with the 1.5 three-cylinder Dragon engine. Use our vehicle lookup to confirm fitment or see the Vehicle Fitment tab for full details. Installation is simple for existing FLASHlink users. Provide your VIN at checkout and a tailored version of your current Stage 01 or Stage 02 file will be supplied to install via FLASHlink. You can revert at any time. Important: Requires an existing 09 Design Stage 01 or Stage 02 calibration. Phone shown is for FLASHlink app illustration only and is not included. Additional Information Brand ZERONINE Design
