Yes, Please, Todd. I have the Tiny Tach, but it is true to it's name. I'd rather install a 3 inch circular one.
Rusty said I'd need to divide by 12 to use the EC2 output. Right?
How much?
Regards,
John Slade

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...  :-)
