We are currently working on 2016 Fiesta ST support! Even though they don't make physical changes to the car, there are typically small ECU changes from year to year. Therefore, we just have to do our due diligence in looking at everything to make sure the car will be properly supported. I don't have a time frame right now, but if you bought an AP3-FOR-001 Fiesta ST Accessport today, you'd just have to do a simple update on your computer at home using AP Manager once support is ready. You can also always email us the vehicle ROM (ECU image) if your vehicle is unsupported and we can add support.
