Technical Upgrade for SS Tach.

Has anyone come up with a device that really works to make a ~63 Chevy SS tach accurate yet with electronic ignition ??
Some claim to, but don't work.

BTT added with Electronic Ignition...

 

Your tach does not care if you have points ignition or electronic ignition. The tach counts the amount of times it fires in X amount of time. One wire goes to ground, one goes to switched power and one goes to the positive side of the coil. If you are running an HEI the wire that goes to the positive side of the coil goes to the pole on the distributer that is marked TACH.

If the tach is accurate with points ignition it should be accurate with electronic.

 

I wonder if you could buy a new half sweep tach and put the guts in your case and behind your face?
