Just picked up My 2013 1SS Manul 6 spd. late yesterday . After scouring the owners manual ,I ended my reading with two enigma's [I'm sure they'll be more to come]. It explains everything about launch control except how to engage it ! Which setting should the T/C & Stabil-Lock be in ? Also, is there a site somewhere on VIN decoding,as the fuel requirements state that only "models with an W or J VIN need to use 91 or higher octane fuel" . Well I do have an X half way thru my VIN, but there are other letters as well.So I'm not sure at which point in the VIN are they referring to.I'm gonna run the higher octane fuel anyways, but would like to know if its safe to use the lower grade fuel in a pinch..
