Not exactly. The FA in the car will not be altered by normal FDL Coding, and for most people it will remain factory original. However, it can be altered, and some people do alter to add options (4U2, 6NR, etc.), and that can be written to the car. So, if that is done, you would no longer have a factory FA in the car, so reading FA and VO Coding an ECU will not produce factory results in the modified FA affected that particular ECU.

So, as you did, you make a back up of your original FA that you can always use to VO Code your ECU's. You simply need to load it and VO Code the modules. You can leave the altered VO written to the car as is.
