I believe the BMS DP Fix should simulate OBD II readiness? As this device sits between the secondary O2 sensors and alters the signal given to the DME.

I'm not sure how it would interact with the Dinan tune though as I am assuming the tune inhibits emissions related check engine lights. Would the Dinan tune with the OEM xpipe allow for OBD II readiness?
