Bounty Hunter Fast track

[sony]

I was looking inside my BH Fast track and it is very fine machine,although it is cheap and have very "stupid" look case.....I was thinking if it is any mod on it.....Is there any chance to add no-motion mode,or some pinpoint mode on it? Very simillar case was earlier with Classic I, than somebody added knob which connect 12 pin of 4066 to minus so it starts a sort of pin point mode...
Any mods ?
