[QUOTE="Attila, post: 1185314, member: 19123"] The infamous Power Commander for the FJR has no provisions for altering the ignition timing however units intended for use on Busa's and others do. While it's true that it's not necessary to change the timing on a FJR it would be nice to know what it is just as knowing what the cam duration is or how big the throttle bodies are or, how far is it to Tucumcary from St. Louis........I jus gotta know! The fuel curve on the FJR is lean on the bottom and takes a dip at 4500 but from 5,000 up it's not far off on the AF ratio with just slip on mufflers and no cats like mine. The Power Commander is another story however in addition to things it doesn't do, timing is one of them. Oh yes, the view from Sandia Peak over looking Albuquerque on a clear summer evening is spectacular to say the least. [/QUOTE]
