 I also own a '73 BMW 2002tii. Great car, though it is currently awaiting some overdue rust repair . . . .

Another point I wanted to make (somewhat unrelated to the original post and sub-section of this forum) is that while modern wideband O2 sensor controllers can be a great asset for tuning older cars, they are only as good as they are set up to be. Have you properly calibrated your sensor in free air? Are you 100% sure there are no exhaust leaks? It can be easy to obsess over minute changes in A/F ratio and lose sight of the big picture . . . .

Make sure that the mechanical and ignition side of the engine are good, then make sure your wideband setup is properly calibrated and leak-free, then circle back to the fine-tuning.
