The designation TDT is in common enough usage that R-ckauto uses it to distinguish the wagon from the sedan. It seems that your approach to a mechanical control of the VNT is more likely to be successful for the majority of people. Electronics are great for engineers but problematic for the average Joe. I can build a linkage based system and have it work long before I got an electronic version to function. Perhaps a slightly more efficient setup could be produced electronicaly but how would you know what factors to optimize and how reliable could it be made. KISS is one way to look at it. Or my favorite "When in doubt, make it stout, of things you know all about" Cheers Dan
