I have my SHO setup to pass emissions and set all my readiness monitors WITHOUT shutting off any codes with Catless downpipes. I did this by changing how the ECU interprets the cat monitor readings and thresholds. I'm happy with that capability. Some tuners will not do that even if they know how due to liability. That's one example of what the software with SCT can do.
Me personally, I wouldn't go readily posting the info you have about bypassing the Emission's protocols via ECU reprogramming. Especially to the extent you've described.
Turning off 02 sensors to avoid the irritation of a CEL staring at you is one thing.....
However, completely bypassing all the protocols is a whole 'nother level.
Most tuners will not perform such alterations NOT merely because of the liability as you state in such a laissez faire manner..... but entirely because doing so is
HIGHLY ILLEGAL and will result in stiff penalties and sanctions.
For those owners who are confronted with visual emissions inspections, and employ catless DP's, the challenges of passing emissions is still an ever present one.
In closing, anyone taking on such risks should understand what they are, for what they are, and be prepared accordingly.
