You can also have a plug to select the map but not have an O2 sensor in which case it is working in open loop mode all the time, this also does not require a CO pot, but one is fitted to US bikes to comply with regs.  BTW I believe the closed loop only operates at constant throttle or with small changes and it is the feedback process combined with set up errors that create the surging. If you are accelerating hard then the system is in open mode. Removing the feedback may cure the surge, but if the set up is not correct it may still surge.
