Interesting. My car is UK spec with no CAT or O2 sensor (C132 plugged in at bulkhead) so it never goes into closed-loop? Does the DME still put the car onto different maps depending upon the information from the blue sensor?
Unfortunately blue sensors are on back order with BMW here so I'm going to put the intake back together and see if the problem is fixed, at least the blue sensor is accessible with everything back together if I have to revisit it later.
