You must have done something wrong.
I turned off just post cat O2 sensor heater with ESKONF and associated codewords and it had no effect on readiness.
Have you changed the codewords for SAI also, or just ESKONF?
No only CWKONABG = 0 (no cat) and CDKAT. CLASLV, CLASLVE, CDSLS which one should i touch? I read what you have wrote but my rear O2 is in position and its new. |

With all this set, do your fuel trims still learn? |

Yes, but just to be clear, I have only done post cat O2's. |

Thanks phila, so setting both bits set 00 (slp/slv/etc) leaves it untested/skipped is the way the way I understand it? Thanks for your clarification. Previous statements imply that setting bits to 01 and not 00 would leave it tested, but no faults set... Thanks goes to elRey too, I know he's been preaching ESKONF for a while now... |

I haven't looked into SAI, but if done properly you do not need the error classes. I will have to double-check, but IIRC CWKONABG and CDSLS will affect evsup1. Anyway, in my last post I was trying to say that it sounded like you got some bits wrong when you modified ESKONF. |

You need to set the bit pair to 11 to disable it. The ME7.5 FR describes setting a whole block (one byte or four bit pairs) to 10 to skip the block, but from what I can tell setting the bit pair (11) is the way to go. The hard part is to accurately identify the bit pairs. |

Oh i see allow me to describe my way of disabling it: According to documentation: 5 / .. 920 / 1 | NC | NC | ERP 65 | SLP 66 | 11 11 10 11 = 251 032RP eskonf: 170 255 0 48 207 248 48 So 248 == 11 11 10 00 meaning SLP has 00 -> active diagnosis. Then to disable it since is not connected SLP == 01 so: 11 11 10 01 == 249. Is there something miscalculated? |

The bit locations are ECU specific, so unless your ECU is specifically described in the FR then the layout of ESKNOF may be different. Why are you using 01 vice 11? |

I see. 248 value can be analysed only this way i wrote. No other combination can give as result 248 dec value. So those bits are self explanatory in every ECU. I use 01 instead of 11 since i dont want diagnosis to start in any stage. Same philosophy i used for remove N75, N249, N112 and works as should be. Always i am open to read and understand something new, so i am so eager to read your approach. |

By layout, I am talking about what functions the bit pairs represent. I have compared 5 different binaries, and none of them exactly matched any of the layouts decribed in either FR. AFAIK, the only way to completely disable diagnosis is with 11, which represents component not included. The nc fields are represented as 11 in binary. |

I think he means that there is only one contiguous '00' in 248... and that must be SLP |

I've tried solution as phila_dot suggested, but no luck... What is extremely weird is that over time my o2 sensor shows richer and richer mixture while leaning it.... After about 10 minutes of driving i see this even in idle (idle.xls) READLINESS STILL NOT PASSED  Additionally I did some logging with me7logger (lambda_20121009_184254.csv) Lats file attached: my current bin... |

Yes, but that is only one of seven bytes. I would log the cycle (Z_) and error (E_) flags associated with whichever readiness test is failing. That will show you the root of the failure. Also evsup1, but I can't provide the location for his ECU. I'll check CWKONABG, but IIRC that should only affect ready.0. professor, if you post our bin, I will try to check it out sometime. |

The bit pair that I provided should only remove diagnosis of the post cat O2 heater amplifier. That looks like the same ME7L log posted the other day. Did you get those other issues sorted? |

My only real issue atm is with front o2 sensor freaking out over time... I mean it goes from 1V to ~0.7 in 10 minutes (at idle)... Sensor is brand new, I've tried also with maf unplugged just to be sure, but same result... BTW: Log is taken today and is brand new... Also I'll try tommorow to drive a bit longer and see maybe it needs more km to actually pass the readliness... |
