I was kinda hoping that I could use the clean area inside what is now the distributor to do the position readings. I would love to have it all done with just one reference point and a counter for the reading but I can't think of a processor (that I know how to program) that would be able to count the notches and run spark and FI timings at the same time. This is where it gets fairly hard. If I had an absolute reading ( 0 to 255, or even to 1024), I could have the processor start working anywhere in mid-stroke(usefull if the system glitches) and it wouldn't have to multitask (which I don't know how to program yet) But all of this stuff is something I am most likely going to have to come up with on my own. What's really bothering me is this awefull flapper. I know it's nessesary to get the proper vaccume but if I were to create another source for the vaccume, say the input end of the smog pump, (or whatever it's called) would it be sufficient? also what sensors would I need to bypass or adjust?

Also I will be posting an online Journal of all of this with lots of pictures as soon as I have time.
