Also does anyone know what shift table is used when the transmission selector is in manual (M) and you have used the button to increase to M6 or M5 or M4,..etc? This shifting pattern seems to be a nice blend of performance and smoothness I would like to copy it over to the normal if possible. thanks for any help
