no, with your timing plate you keep the same ignition curve you just advance it whatever 3,4 or so on degrees. with the fs you have the choice of stock or three other timing curves and with the proper equipment and knowlege one can create one own curve to get your bike to do something specific. if you are boring enough you could just add 4 to all the curve points and it will react as if you turned your timing plate up 4 degrees. I have mine set up to run a advanced curve until the nos is activated, then it swiches to a more nitrous friendly curve. so, if you are serious about going fast it's a pretty refined tool that does alot more than a timing plate could ever hope to do.
