I was pretty jazzed reading about the adaptive spark technology until I got to thinking....."hey, a knock sensor does the same thing, doesn't it? And they've been around forever". Am I wrong on this? Or is AST just a FoMoCo marketing code word for 'knock sensor'? And if so, why wouldn't they have been on all Mustangs for the last 10 years or so? What do you guys think? Thanks.
