I installed a 123 Distributor in my 1969 S2 and recently had the tach converted so it will read with both points and electronic ignition. It works well on both systems but reads a constant 15% high on both. I contacted the person who did the conversion but he hasn’t returned any of my emails and doesn’t appear to be in business anymore.
Is it simple to adjust the electronic tach or should I send it to another vendor?
