This helps incredibly. Can't thank you enough. I've been a BMW nut/shadetree mechanic turned shop owner, and the new technologies were starting to pass me by. Finally got my own 335i, and installed a Procede just a couple weeks later. I am sold on the capabilities of the Procede over even custom tuning. After working with some professional tuners at all levels, I like what I read and hear from Shiv.
Not sure why some do it, but 12.5 lambda at low revs isn't necessary on this engine. No risk of detonation, haven't seen logs of anyone with timing pulled from the knock sensors, either. Warm, fuzzy feeling is fine, but don't do something the old way just because it makes you feel better.
