Does the BMS DPFIX have a by-pass mode?

@ Terry@BMS and the rest of you who have the BMS DPFIX, I have a few questions:

I've recently passed my emissions test in IL (with flying colors ;) ) and now that Cobb includes suppression for the cat inefficiency codes, I am wondering if I can disable the BMS DPFix until I need it again. I'd like to keep it in the ECU box, but dial in a setting that will essentially by-pass the signals.

Is this possible, or do I have to remove it completely?

My main reasoning for doing this is that I've read a few posts on the other forum stating that the fuel efficiency suffers a bit and that the AFRs might be affected if you have COBB and you leave the BMS DPFIX.

Comments, suggestions and feedback are welcome.

Thanks
