Monitors must be set ready to pass (drive cycle complete). Also, emissions for Catalyst and O2 sensors must be supported in the flash/tune you have on the dme or the State computers will ‘flag’ and fail the car outright.

This means if you have MHD, flash with ‘OEM/Ca tted D Ps’ checked, yes checked. Or back to stock if you have manipulated or tuned out the ca ts/secondary O2s with TunerPro.

I don't believe the JB4 (USA) settings will make a difference though you may need to experiment or require a d p fix with your setup to enable monitors to set ready for emissions tests.

You have an extensive mod list so visual inspection could be problem as well.
