Here goes nothing - this is my first reply to a post, hope it works. please bear with me.
For almost two years I had a problem with my [purchased used] 2008 GS "hiccuping" at engine speeds >5000 RPM. Battery light would flicker, battery tender gave the unit a full charge. Dealer read BUDS, said bad speed sensor on rear wheel, replaced. No cure. I removed evap canister, replaced plugs, wires, coil and better. No change - <hiccup>. Then Lamonster suggested checking the master frame ground connection for the battery located under the seat. At that point I would have pulled monkeys out of clowns' butts if iI thought it would work. Although the bolt and nut could not be turned by hand, they did move with wrench. Torqued the not/bolt tight and viola! No more hiccups!
So while I don't know the details of how DPS works, what the heck, Spyders are touchy on the electronics, give it a whirl.
Good Luck!
