This is an interesting thought although I doubt the KS unit is seperate for Digi 1. Just interupt the hall sensor to the KS unit and run it through the MS. That way you can control the advance and have KS also. You'd just need to keep in mind that the KS unit has a built in advance curve and what the engine sees would be the sum of the MS advance and the KS advance. Basically, your MS advance would be pretty flat.

Should you go to a crank trigger the use the V3 board with MS I CPU and MSnS-e software. MS II currently does not support multi tooth crank triggers although they're working on it.

16V IAC is not supported.
Dumb 8V IAC needs no support.

MSnS-e supports knock sensing, but requires extra circuitry. Look here:

Agree. See the LC-1 at http://www.innovatemotorsports.com/
It's the least expensive unit out there.

Not to be a dick, but balls to that! Scott's units start at $500.
Check out the kits and completed units at www.diyautotune.com or I can build you one and save a few bucks.

Sometime in 2010 was the completion schedule I heard! ;^)
Just busting your chops Big(VEMS, VEMS,VEMS)Mac!
