Audi Coupe

Hi there. First greet you all since I am new in the forum.
I take this opportunity to release a question, that by the way I do not know if I will have put it in the right but good subform.
I drive an Audi Coupe 2.8 V6 of 1992 and at the time he was given the chimatizer option (the same one that led the first generation of the A3). In the Misma after operating a sequence of buttons you enter the car computer menu. Here only the number data without making diagnosis. Well, my questions is that it is every value that gives you, for now only the 17 and 26 that are the speed and the real revolutions.

I hope you understand me what I want to ask you.
Thank you very much and I wait for your answers or clarifications
