Bill at CJ Pony Parts shows us how simple it is to flash a stage 1 tune onto the Ford Focus ST. Cobb’s AccessPort V3 is a very popular tuner, for not just the Focus ST, but the Subaru WRX, many turbocharged BMWs, and more.
The stage 1 tune can be flashed in minutes, and instantly improves the drivability and unlocks hidden power of the car. The AccessPort also has off-the-shelf tunes made for common mods such as intakes and downpipes. It lets you monitor ECU parameters and make sure your engine is running healthy. All around, this is an essential mod for the Ford Focus ST.
