FADEC Part II, Forgot to mention that the first FADEC type system was pioneered by Porsche Mooney from a basic Porsche style flat 6 auto engine and installed in a a Mooney airframe and sold as a Porsche Mooney. A similar system by Bosche was installed on the 2000 cc VW flat 4 aircooled engines that were in the 1980 to 1982 VW Vanagons. I have a 1981 Vanagon with one of these engines and it is a gem. Norm
