On the E40, is there any way to disable adaptive and integral modes? Zeroing them perhaps? The reason I asked is my car has been idling rich and for whatever reason, "it" decided on one drive to run much better and even dropped the CEL, then the next drive went right back to being rich I'm convinced it switched modes and which ever mode it was in was leaner. So I figured it would be a good idea to isolate each mode and see how they behave.
