NP!
The NOP's disable all the emission codewords altogether.

It just sets all of them to "Not Supported"

I guess my question is, what is the best way to set full readiness if you have completely removed your rear O2s?

I don't think the DTC flags directly affect readiness. I think that the CARB flags need to be manipulated. |

Correct. Just deleting the DTC's will not get you readiness.

I've done all the tests and coded out tons of stuff. Still no clue on how to get oxygen sensor readiness to read its OK with my rear o2's removed / coded out properly... I'm with nyet on this one.

When you run through the readiness test with VCDS, what test is failing? Remember, oxygen sensor readiness includes the front sensors as well. |

I'll re-run the full list of things tonight and let you know precisely what works and what doesn't.

Modules DIMC and TC6MOD seem to outline the process of readiness testing.

What I am saying is modify the function that SETS the DTC to actually SET the readiness instead of the DTC. I'm talking about a code modification, not a calibration change. |

I may have a way to pass O2 readiness without having a cat. You must have a rear O2 sensor plugged in though. Let me see if I can find the info and post it.

You can modify the thresholds, but i don't remember exactly how I used to do it. I have since yanked my rear O2 s and used the bungs for my LM2. I will check when I get back to a computer (posting from my phone) |
