Just had the emission issue this morning. Put the Velos tune on a few weeks back. I've only driven about 200 miles since then. Went into the emissions test this morning and got a "REJECT" result due to the Catalytic Converter and Heated O2 Sensor coming back as "Not Ready". Everything else came back as "Ready".

They say if the battery was recently disconnected (I replaced mine during the tune process) or vehicle recently repaired the vehicle must complete one or more manufacturer recommended drive cycles. Not sure what BMWs would be.

@TempeAndy - any info you can share if you resolved the problem? Thanks in advance.
