Man, if you have bought the Tacho Universal already, you are supposed to be one of those fellows who do odo correction. There is a user manual with each unit, you should be able to read and use it.
This forum is not for hardcore car service professionals, but for general end-users. If you still need more help, please get in touch with a professional in the field. Nobody of us knows this stuff. All we can do is google for you and provide links. That you can do yourself.
This is the manual for Tacho Universal. Pretty neat in itself, but you need to learn the stuff from somebody who knows how it is to be done. It will most probably be another garage which deals with odo adjustments.
