As a side note its worth mentioning in order to get a working standard look rev counter a 90 spec Xr3i item will be needed and conection to the edis module using pin 11 for the feed to it

Added! I forgot about this, may have a workaround rather than replacement though......
I have read that you can use the coil of a relay to boost the tacho signal (See "Hi Voltage diagram" on page 2 here:
http://www.extraefi.co.uk/Drawings/P...cho_Wiring.pdf) I know this is for a megasquirt and I haven't tried it. But it may work for the non EFi rev counters. Anyone have any oppinions to offer on this?
