Thanks for this explanation. I knew that ForSCAN was a RE tool (Russian guy?) and that there were others out there for multiple purposes on various product lines. I also knew that ForSCAN did not support customizing all OEM functions. I just wasn't bright enough to make the connection between this being a first party versus anybody's tool type of mods that one might make. I do most of my own auto maintenance so I use the tools that best facilitate the process and since I am only mechanically experienced and not an accredited tech I lean towards using third party tools, custom tools I cobble together, OEM manuals, etc. to guide all the work I do here in my driveway or shop.
