progress, and more understanding
Attached are a couple of pics of my tach
divider. It can be set to divide by any number necessary. I can't guarantee it
would work with any tach but it works very well with my cheap
off-the-shelf-at-any-autoparts-store, Hastings tach. I have a few more if anybody wants one.

The EC-2 tach output has 12 pulses per
revolution, and won't directly work with any normal tach. Todd has made a
divider to bring the pulse rate down to normal, and it sounds like it's working
well. The TT that you have expects 1 pulse per rev, so if you don't mind
dividing the rpm reading by 12... :-)
