Power Commander and Ignition Timing Questions

[ATF]

Got my Monster 796 ABS up to 97 BHP at the rear wheel using a SC-Project full exhaust and custom PCV map done on a dyno. I'm very happy with the performance and it's easy to stop low rev surging with the PCV if it bothers you that much. However I have a few questions:

1. Is there anyway I can adjust ignition timing?

2. Does anyone have intricate knowledge of cam upgrades?

3. I am just about to re-map the PCV by cylinder and gear. It is already mapped  per cylinder. Is there a 0-5v supply available. Dynojet says there isn't but the GIPRO uses the underseat plug to calculate gear position.

4. Do you use the black or white wire on the rear wheel speed sensor to calculate speed?

Please help me with whatever you know you don't need to know the answers to all the questions. Thanks!
