Been tuning on this new to me 1999 R1100RS. Reset the TPS and throttle plate angles to "latest" procedure and deactivated the dobeck 1033 on the bike. Ordered a AF-XIED to play with. The prev owner told me that he had replaced the O2 sensor and I found the original one in a box labeled "Bosch 15727 WIDEBAND O2 sensor". Could this be the O2 sensor that is currently on the bike? Will the motronic run with a wideband sensor?? I'm trying to figure out what I have before I install the XIED.

Bosch 15727 O2 sensor on R1100RS

It’s a narrow band O2 sensor with a pigtail in place of an oem connector. It should work fine if it’s wired correctly.
After lots of reading it appears that this is indeed a universal 4 wire narrow band sensor. Curious that Bosch states wideband on the box. It is available as low as 25 bucks and comes with the "smartlock" connector stuff. Seems like a bargain. I will be removing it and replacing it with a 11 78 1 464 492 / BOSCH that comes with the connector ready to plug into the bike harness. A new sensor is probably not a bad idea when adding the XIED.
