I have read a great deal on some of the BMW forums about the need for a CO Pot. Just make sure we are talking about the same thing, Carbon Monoxide Potentiometer. Some of the forums say it is there for idle and needs to be set with an exhaust gas analyzer. My bike, a US bike, didn't come with one and the codes from the Moronic gave me a CO Pot code.
If I ignore the coding plug issues and forget about oxygen sensors, I know that that Moronic requires only two systems to run in open loop: Timing signal and Oil Temp, or otherwise known as the ECT. After the Moronic sees other signals, it uses them to bring the system to closed loop, for optimized fuel and timing control. There is still no way to actively see closed loop in the Moronic. Closed loop is an assumption. Like all digital-analog convertors, refresh rate is too slow to see real-time data.
Oh I might mention that I was Bosch tech rep for about ten years.............
So my story; I got a CO Pot, installed in the existing harness. I was just curious.
I like my idle very low, about 800 rpm. It's a preference and no real need to weigh in and tell me that's not to spec.
I noticed on really warm days that throttle response was not "crisp" off idle but the solution was obvious. Bring the idle rpm up a bit and see what happened.
My replacement got me a CO Pot, oddly, they are used on a wide variety of manufacturers, including Mecerdes. The list goes on to include almost all the Germans and a bunch of Asian cars.
Now I have a "promo" $70.00 part and about the time it takes to crack a beer open, installed. I didn't touch the thing, no adjustment, just dropped it in. Idle dropped to about 700, bike makes a different sound at idle, call it happy. Takes off like a rocket. Great change coming off hot cruise to a stop, doesn't bounce off low idle, sounds happy.
My little 3200 to 3700 rpm "buzz", gone. It's just supposed to act on the Moronic open loop at idle. I thinking there is more to it.
Best part, no codes in the Moronic which makes me think, when I have a problem, it might be real.
I'm not going to get crazy about the "why's" as this was just for fun, like riding should be.
