This looks like a good solution. I'll wait to see what happens with Rusty.
In the meantime... This morning I got to thinking that all I really need to do is divide the 12pulse/rev high resolution signal from the EC2 by 3, then a tach set for an 8 cylinder, 4 stroke should read correctly. So after a little research, I ordered a NTE4526B programmable divide-by-"N" 4-bit binary counter. So long as I don't need to do any signal conditioning, I should be able to solder this to a small piece of breadboard, with jumpers on the appropriate pins and leads, and it should work great.
Now if it sounds like I really know what I'm doing in electronics, I should point out that my grasp on all this is tenuous at best. I'm being prodded in the right direction by a journeyman instrument mechanic who is very knowledgeable and patient with this lowly apprentice. :-)
