professor, when you verify everything is working, can you write up a summary I can post on the s4wiki...
thanks!

Yes I think we need renew wiki on emission system removal... But only problem now is ESKONF, because like phila_dot said it is not same for all the ecus... In the end we can have these scenarios: No CAT(s) + no post CAT o2 sensor(s)
No SAI
No EVAP |

Whats the way to clarify its ECU ESKONF amplifier order per block? Can you point out the procedure? Thanks  Honestly, I don't have a foolproof procedure. I just try to use every bit of information available, disassembly, comparing binaries, bit patterns, and referencing the FR. I am thinking that there might be a relationship or pattern at least in the pins used in many different binaries. If all else fails, then there is always trial and error. |

how bout an m-box specific list? that would be a good start for the wiki. I can always add a disclaimer to say what things are box specific and not just by memory offset (but also bit position)

Rear O2's and EGT's are the only ones that I am satisfied with our current solution. Rear O2's are posted on page 9. EGT is just CATR, CDATR, and CDATS for complete removal. Solution to run one EGT for both banks here: http://nefariousmotorsports.com/forum/index.php?topic=2668.0title=I don't like SAI and evap because of the effect on evsup1. If I get a chance I will try to figure something out. SAI ESKONF bits are on page 9 as well. |

Hmm... I've tried ESKONF that phila_dot suggested, but readliness still shows incomplete or failed on both o2 sensors tests and also evap... by setting ESKONF do we instantly see passed on o2 heaters or we have to drive for a bit?  |

No, the only way that you should have an instant pass is from the evsup1 bits, for O2 heaters CDHSV. Have you changed all of the codewords for rear O2's that I outlined on page 9. Obviously, with CDKONLS and ESKONLS specific for your car. |

Here's what I did (dec values): CWKONLS => 1 CWKONABG => 0 CDSLS => 0 CDLSH => 0 CDLATV => 0 CDLASH => 0 CDKAT => 0 CDHSHE => 0 CDHSH => 0 CLRSHK => 5 CWDLSAHK => 0 ESKONF => 240 I have only one bank with front sensor and EVAP. No sai, no cat, no post cat o2 sensor... ME7.5 Maybe I should do something with the following maps: CDHSVSA (cur_val: 1), CDLSA (cur_val: 1), CWDLSU (cur_val: 0)... Haven't checked FR on these maps though, just see them in prokonal section... Oh, BTW: Is precat o2 sensor heater still diagnosed with such ESKONF configuration (I mean will ECU still detect DTCs if there should be any for precat o2 heater)?  |

I'm not sure about those other codewords. Front O2 sensor heater should have it's own seperate ESKONF bit pair. I can post the cycle and error flags that get checked when I get home. ME7Info outputs most of them. You can take a quick log at idle to see what's causing the problem. Have you driven the car since last clearing codes or removing power? |

There's no CDLSHV map in my file that I know of... I have CDLSV though, but that's for front sensor, no? No I haven't driven yet after clearing out dtcs... But I did with same flash before that... I can try again ofcourse for few kilometers... |

Fuel trims working. So in order to disable SAI/EGR (total remove, electrical connectors not connected) without catalytic converter you have to make appropriate changes to the ESKONF map according to your ECU pattern for the SAI (SLP) and set CDSLS, CDLSV & CWKONABG to zero (0). SAI and oxygen sensor(s) now have readiness PASSED. |

This is emissions related question so I'm posting it here... How variable B_FAKAT is set inside ecu? I see that it should be set in TKMWL function but I can't find any definition on how it is set to TRUE or FALSE. Anyone care to explain this to me? Thanks

Verified today that phila_dot's method works perfectly with no sensors even connected.

| Parameter | | Location | | Original(hex) | | Original(dec) | | New(hex) | | New(dec) | | ESKONF | | 10C7A | | 00 | | 0 | | C0 | | 192 | | ESKONF (M box) | | 10C7B | | F3 | | 243 | | FF | | 255 | | ESKONF (L box) | | 10C7B | | C3 | | 195 | | CF | | 207 |
After flashing the file with this being the only change, the codes are now gone. Does this mean that if you make those modifications (mbox), none of the settings listed for rear O2 delete in the s4 wiki are needed? I'm assuming for RS4 K/Q box no changes will be needed since there are no rear O2s on the RS4? |
