435 with JB4 emission

clegg · 06-07-2021, 12:51 PM

I just got a 2014 435i and found out it has the JB4. If I set the JB4 to stg 0 and unplug it from the OBD11. Will the readiness monitors need reset via a drive cycle for emission test?

You would not need to do a drive cycle unless you had flashed the dme or cleared codes since the last drive cycle.

Are you catless?

Has cats. The only mod is a BMS intake and the JB4.

Set the JB4 to 0, unplugged from OBDII and passed emissions with no issue. Thanks everyone.
