So enlighten a noob here. Say we install the AccessPort on an otherwise bone stock Fiesta, then down the road upgrade the exhaust, intercooler, so on and so forth. Are those tunes already installed, do we download them from the vendor, or what? Sorry, I'm from the world of old-school turbo Mopars, where we have to solder a ZIF socket into the stock ECU, and then swap in burned eprom chips for whatever mods we have. These newer cars are, well, new to me.
