when i got my k03 chip they sent me back the stock chip, but yea the ecu’s are flash loaded. there are so many different models of the 1.8 it depends on your ecu serial number. if you have a b5 passat opposed to a b5.5 passat/b6 audi a4 your tunes are going to be easier to get ahold of…
oh and yeah someone told me to buy a $300 cable from ebay and use my laptop to burn out software for my 1.8, mmm its not a honda… bank about $1000 if you want a serious professional tune, GIAC finally finished mine 6mos late…
