Hey guys, I have a 9/95 M3 and I'm looking at a Conforti chip from Turner. However, I am a newbie M3 guy (but ask me anything about a Suzuki TL1000R!) and I'm confused about the difference between the chips that are "EWS to DWA" and the ones that are "DWA II". What is the difference, what do I have, and which one should I buy?
