I asked the c5 a6 and allroad guys on audizine which ecus had wideband... no answer yet. Not even a snide comment, which you would expect.

yea 5 wire will give it away, and the ECU hardware WILL be different as the wideband control circuit is built into the hardware of the ECU, its not in the sensor itself. Honestly i would just get a Innovate LC1 and hook that up and use the 0-5v and feed your rear 02's(assuming you deleted them) and theres your "wideband" signal. you wont get a lambda reading, but voltage is fine and can be converted in excel easily. I thought most adc's/dac's will support up to 5v but i would double check with that before doing that  |

Yea thats tough, closest thing i can think of is the b6 3.0 ecu, i believe those are wideband. |

Did we ever confirm if the 03+ 2.7T ECUs have wide band control?

Going off of part numbers for the O2's, No they do not, just the 3.0's had the wideband sensors. This is per Bosch's website.

I looked up o2 sensors for the b6's and they were all 4 wire.
What was the latest Audi model to carry the 2.7?
I'm thinking the allroad... I will look into it.

i looked and 2005 appears to be the last year the 2.7 was used, all the o2 sensors i found were 4 wire... another rainbow with no gold at the end.

Yes, i replaced myself front O2 sensors on few 2003-2004 allroads 2.7, and all of them have 4 wire narrow sensors.

I have tried to figure it out with ETKA but wasn't very successful. For the 03+ ARE and BES engines it seems that it has narrow band.
If you have the wiring diagramms it would be nice if you can look it up.
I just checked now (forgot about this thread lol). Elsaweb diagrams show 4 wire O2 sensors for an 04 BEL Allroad. No wideband here guys, sorry. Schematics are attached if anyone wants them... |

No point posting on audizine about anything beyond backlight audi rings or some crap like that. Time and time over again my technical questions go totally unanswered there and once I went after few people who have build threads over there, 90% of them just pay some shop to do the build and then brag all over audizine about their dyno runs. For technical questions quattroworld.com is the place, there are quite few people who know their stuff in B5 s4 section. |
