Default Wide band questions

Just installed a set of AFR 195s. Went to the dyno and above 4000 rpm the engine started blowing black smoke and filled the dyno bay. I am running a Gen 7 ecm using a wide band and I suspect the wide band may be the problem, and if so How do I know it is the wide band. How long should a wide band last.
Thanks in advance.

How did you do initial tune?
Do you have datalogging equipment ? If so you should be able to see if WB is working correctly
Possible if engine running way rich for WB to get clogged up

My communications cable to the ecm from laptop just crapped, So will not be able to datalog until new one arrives..
