This shouldn't be too difficult with an MS2. We've even got a couple adapter options if you want to make it plug into a factory TBI harness.

Well, an MS2, Stim, wiring harness or adapter board, and a cable to connect it to a laptop for tuning. We have articles on two possible approaches here:

http://www.DIYAutoTune.com/tech_article ... _board.htm

Those should answer your questions about distributor advance, etc.
