OBD2 is a totally different management system, its not the equivelant of remapping an OBD1, having driven OBD2 cars for the last 10 years, it was a real disappointment to jump into my OBD1 Corrado VR6, its now a joy to drive and idles a lot smoother and pick up is more responsive. Its a doddle on the Golf to do, you wont have the hassle I had with my Corrado, chopping looms up and making new ones etc... Pete
