The original distributor can be used. You would need to fix the centrifigal weights inside the distributor and plug the vacuum lines (or just leave them off). The ECU will control the all the advance through the distributor. I guess there is enough overlap of the rotor contact and cap contacts to allow for the various advances.
Folks have done an excellent job of describing the system requirements. I am still a little uncertain as to whether or not the 60-2 toothed balancer and VR sensor (what is that?) are required for all conversions (i.e., CS, CSi, or motronic 1.3).
Could somebody please give a definitive answer on that as well.
Thanks

Now if you want Megasquirt to handle your spark timing as well (like a Motronic system) then you need to give it some form of crankshaft position information, hence the need for the 60-2 crank pulley, or something like it. Other alternatives are the old style flywheel teeth and reference mark setup (theoretically more accurate, but it's splitting hairs and insignificant on a motor like an M30) or installing some kind of wheel in the old ignition distributor and using that (considerably less accurate than triggering off of the crankshaft since the distributor is subject to internal play, play in the drive gears, and timing chain slack.)
