It is not the transmission final drive, but relates to the ratio of the speedo drive.
There is a table at the back of the book which gives you the correct ratio to insert. From memory, it is 0.77.
You only need this if you are using the original speedo cable, as opposed to the digital inputs that are available as an extra.
Good luck.
