I didn't mean to offend you if I stated the obvious. I totaly understand wanting to "do it yourself". I love doing as much as I possibly can myself. My thinking about Eurocharged was to make it easier for others that don't have your expertise to buy kits/ partial kits from you. The software needed to do all the tuning in the ECU is cost prohibitive unless you intend to go full time into the tuning business. Having a tuning solution that is proven from a well respected tuner such as Eurocharged would help others that want your system. I was only suggesting this from a marketing stand point. If the AEM is required, the wiring alone would scare away most people.

As far a DAS goes. I tried to get training on developer mode and the only place I found required me to be a professional repair shop.

Developer Mode is German only and there is no way around that.

JC Recording has some informaiton on Developer Mode on their site as well as a forum to ask questions. This is probably your best resource. Also Rudy has spent a lot of time self teaching himself and knows quite a bit.
