The EEC IV computer takes care of all the advance functions, if you noticed when you change your cap and rotor the rotor is fixed with no mechanical or vac advance provisions. The computer adjusts the timing advance ( or retard) curve based on programmed parameters, up to a total maximum. Moving up the base timing will increase the maximum total timing, thus fooling the computer to allow some performance
