Bosch L-Jetronic Fuel Injection AFM Adjustment & Tuning - Part 3

NOTE there are a few things I should mention:
1) I am NOT adjusting a stock AFM on a stock motor. So I will be going more teeth one way or the other than is probably prudent for a stock setup.
2) I am using a 1984 BMW 318i AFM on an 1982 Opel 2.0L system. Because in my case it was easier to source in the US.
3) The BMW system DID incorporate an O2 Sensor and Lambda. The Opel system did not.
4) The Opel motor has larger valves that stock, a larger exhaust than stock, and a mid-range cam.
So, I am adjusting the AFM to compensate for those changes. So YES I can go 5 teeth or more one way or the other. It does run good that way as well. But as others noted, if you are adjusting for a little more power in your Stock setup, one tooth one way or the other maybe all you need, and any more will probably not help your setup.
