Just fitted version 2, replacing version 1, running it from a standard cable. Measured wheel circumference. The speedo is 3-4 mph higher than a sat nav. How do I adjust? Also the Rev counter seems to be showing at half the expected revs. Any thoughts?

reduce your wheel circumference until it's accurate

Your ignition setting is wrong. If I remember right it only has a few options for ignition.

He's my settings if it helps
