Exclamation Koso Rev counter help.

Has anybody used the rx2nr Rev counter.
Its a koso unit from america.
Seem to be just what I wanted apart from Im having issues with getting it to read correctly.
Its bouncing around like a fat bird at a donut stand.
I have taken the counter feed off the ECU.
Im told that a feed off each coil will give a better result.
But im not sure what wire to join it to?

If it still does it after your try to fix it, try installing a capacitor on the ground side. I had an Autometer tach that was doing that on a VW, and it helped.
