Building and electronic speedometer adj?


I recently built a "DIY code reader" using schematics from folks on this site. It was fun and works great.

Now I'm wondering how hard it would be to build an electronic speedometer adjuster. I know that these are currently available for sale for those whose guage is off due to diff or tire changes.

My understanding is that an electronic pulse is sent along a wire to the speedometer. It is this signal that needs to be modified.

Any thoughts?
