Hey

I know several folks have had success with the Tiny Tach. I am interested in hearing how it had to be programmed for good results. It has to be set for the number of sparks per revolution.

Robbie,
I have a tiny tach installed and I believe it is programmed to the "360 degree" setting. Since the AeroVee uses a wasted spark ignition, each plug fires every 360 degrees,
the tach will pick that up. I believe the electronics inside see the one pulse per revolution, processes that info and determines that that is one revolution then displays
as needed. i.e. it sees 1,000 pulses in 60 seconds and displays 1,000 rpm. It also can be set for "180 degree" and other settings easily.
They are very easy to program and if I'm wrong in telling you what I have it set at, it can easily be changed.
I use it as a back up to my electronic tach, hour meter, flight timer instrument, Flight Data Systems T-30.
I'm in Houston away 600 miles away from my ONEX so I can't double check what I just relayed to you for another week.
In a nutshell, It works great.

Robbie,
One thing in the instructions I forgot to relay.
That is to be sure to not wrap the signal pickup wire more than 4-5 wraps or the display can be erratic.
I found this to be true in my attempt to over-do, again.
