This forum being the former "birth place and home" of the Bürgi-made chips, I'm kindly requesting advices from you. I've been hunting Bürgi's chip for the 1B engine. I know that Bürgi hasn't been here for some years, but I'm hoping that one of the current forum members might still know something.
Anyone know where I could find a Bürgi-made chip for the 1B engine? That is the MAC12D with single knock sensor and static maps for frequency valve map control instead of lamda-loops. I've studied the insides of the MAC12 some bit and almost dare to say to know where every map is located and what the values mean in the code. But because I know that someone already has tweaked maps that are tested and proved to be really good by many, I rather not spend my time on trial and error to do the same thing again - and most likely with much worse results. The "someone" (or almost the only one when it comes to 1B) who has made it best, is for my best knowledge Bürgi.
So I would be more than happy to get only just the raw code but I'm evenly happy to find an actual chip with the code inside. Every advice, hint or just thoughts are welcome!
As an introduction, maybe couple of words about me. I'm an Audi-hobbyist from Finland and especially been sharing the love for the typ44's


This english part of the forum seems to be a bit quieter, but I thought to first try here. My german skills are not the best and rely on most part for the google-translator, so I hope this reaches atleast some of you and I don't have to embarrass myself trying writing german to native speakers

cheers,
Anton
