As Andy mentions earlier, Megasquirt can be used to control just spark.
Megasquirt in conjunction with a <gasp!> Ford EDIS ignition module, coil pack, VR sensor and 36-1 notched wheel mounted to the crank pulley will give you distributorless ignition at a great price. EDIS has been tested accurate to 9000 rpm. Another benefit is the ability to piggy back another coil pack onto the ignition module to allow for twin plugging.
If you build the Megasquirt yourself and salvage the EDIS parts, you can realistically spend no more than $400 for twin plug, distributorless ignition.

Yup, my budget 930 project is going the MSII + EDIS route.
A new EDIS ignition controller and coil pack can be had for less than $100.
MSII can be had for less than $300.
I have an EDIS trigger wheel from a ford V6 I might use but I am also concidering making a custom unit that is incremented every 5 degrees instead of 10 and has two missing notches on oppositve sides of the wheel so I can set up an ignition trigger where the air pump drive pulley on the left crank used to be. I need keep the pulley housing since my turbo scavenge pump mounts on top of it so I figured I might take advantage of it assuming the inductive pickup can deal with the tighter trigger notch spacing.
Since everything is apart and I am planning on putting my massive 930 pressure plate on a diet I might notch the continuous path around its side and set up a trigger on the bell housing instead.
Ah, so many possibilities, and all so cheap when you can do it yourself.
As far as reliability goes the EDIS in my ford escort is still running perfectly after 220,000+ miles. Thats good since its supplies the trigger signal for the EFI.
