I am installing an 8:39 ring and pinion in the car and might need to do something simular.

The only problem is that I don't want the odometer to be out of synch so I was planning on puting a signal pulse multiplier/divider into the circuit instead.

Does anyone know whether this adjustment only calibrates the speedo or if it also adjusts the odometer circuit too?
I don't think that this fix will work for a change in ratio. It is more of a zeroing adjustment.

Don't know if it will work with the Porsche but there is a product called the Yellow Box that is used to calibrate motorcycle electronic speedos. I've got one on my 'Busa and they work well. You can get one at Black Robotics (http://www.blackrobotics.com/). I'm guessing that this is the answer that you are looking for.
