Hi,

Here the japanese RS4 version 8D0907551Q - 0261207141 - 1037360388 without cat control.
The 551Q fits 1:1 with the 551K binary. Wink

Is this a better starting point in your opinion?

The 551Q is very close to the 551K.
Mainly the japanese RS4 has no cat, no rear O2 sensors and no secondary air system build in.

So in the 551Q software are DKAT function, rear O2 sensors incl. heater and secondary air, already set to "0".

I believe the 551Q is the better start.

Would installing this on a standard APB + K04's be an issue since this car has the SAI? Would we just have to disable that stuff? Embedded emissions controls are somewhat scary stuff...

This is the file I'm going to start with. I have no SAI, cats or rear O2's.

Just to clarify for everyone. SAI only came on post-update Tiptronic cars. Please if anyone has information to the contrary, this isn't an issue for most of the 6mt enthusiasts that dwell here typically.
