Default Wasted spark = double revs on my tacho - HELP

When i got my cossie it was on wasted spark. The old elliot tacho died so Matt put back in the standard tacho. Standard one reads the idle but anything over 2k revs it goes spastic and drops below zero i think.

My mate happened to have another elliot gauge so has put that in and now the gauge moves but seems to read double what it should be reading.

How can i fix it?
