Let me appologies right off the bat for being such a squid. I boght the A4B706, I bought the VAG cable from Ross Tech, I searched through the forum to see if there was an idiots guide, but I'm still in the dark. Is there a how to from start to finish on what steps I will need to take to get this done? how do I get the information to plug in to the excell sheet t determine the HP? Once again, I'm sorry for having to ask the question, but I'm really interested in learning ho this is done.
