Anyone using or familiar with UMA instruments tachometers?

I was considering the 2 1/4" P/N 19-519-203 for 3 pulses per rev
connected
to the negative side of the ignition coil. I'll be using LS1 coils.

Any comments or words of wisdom?

Thanks
Jay




This tach is for a distributor-type ignition. You would need some
external electronics (simple, possibly just a diode from each trigger)
to sum the signals feeding your LS-1 coils into the tach . Use the -203
for a 3-rotor or the -202 for a 2-rotor.
