Hi, today I bought one at my L.H.S. with the assumption that I could switch steering rates "on the go"... But, unless I'm missing something (wouldn't be the first time) it looks like all it has is a variable rate steering? I want to be able to go from about 60% to 100% as I go from a high speed run down the straight, to a relatively sharp turn around at each end. (I drive at an abandoned Air Force base runway, and want both rates, instantly switchable, with my Schumacher Fusion .21 T.C. that can get up to almost 80 M.P.H.) There don't seem to be any instructions regarding programming a true "dual rate", and via experimentation, all I seem to be able to get is a variable rate?! Am I not doing something right, or is it "mis-labeling" on the box??? Thanks...
