I used a cheap door bell button and a couple of pieces of wire to recalibrate my speedometer. The instructions to do so are in an article in the Morgan Club newsletter and are linked to in the first post on this thread.. I played around with mine and got the speed shown to match up with the GPS speedo on my phone.
