I don't know much about cars, ecus or whatever. I don't know who's right and who's wrong, but your remark shows you have NO class. Gred D. does not put you down in ANY way...yet you indirectly refer to him as a "fucking moron"?
I think you just lost a lot of "respect" if you can call it that, from a lot of newbies like me who's never actually dealt with you.
