Did not exist.There are AKH and AHK. AKH is S8, AHK is S6+.
It's not really the ECU that is needed, what is needed is the software off it I think.
ah, thanks for clarifying =) i did not get an ECU with the engine, what should i shop for to get a stock one?
think he is looking for a completely stock ecu, which is why i listed the numbers  i wonder if the AKH ecu is compatible with the ABZ.. wiring harness, sensors etc etc.. if so, then that would be the ecu to fetch for his build. |

i think i found a 1998 A8 ECU with all the immobilizer stuff. it says it has a 300HP 4.2L V8 so it's probably the right code. I'll go check it and pull it.
can someone confirm that the immobilizer ecu is in the cluster? there's probably an antenna on the ignition key surround. does anyone have a wiring diagram so i can confirm what i need?
I'll go ahead and try it without any fix for the auto transmission and see what codes it throws.
Thanks!

What is the ECU code?
There are different ECU's for different engines, different injectors, different MAF's.
I looked into this a bit more...

I posted a euro bin a page back, maybe prj can tell you if it'll work.

The AHC, AHK and AKH all have different MAF and different injectors. So my idea goes out the window. Comparing AKH manual files between each other could yield a solution as to what to modify in the ABZ. I have a car or ECU coming to me soon, so I will have to do to this myself... |

prj, can i ask what your reason for this engine is? are you swapping this into something else with a manual transmission like i'm doing? i just got my bellhousing adapter finished yesterday. it uses a volvo M46 bellhousing to adapt the Audi V8 to the porsche 944 bellhousing.   the extra material is where i'll be mounting a hydraulic external slave. i just left the extra material for now. the bores are also still undersized because i haven't figured out what i want to do. i may add an extra support bearing for the extra driveshaft length. but either way it is now good enough to allow me to make engine mounts then make an oil pan. |

I am not swapping anything.
The client has put this engine into a B3 shell.
But he says the engine dynamics are way off, feels like a limp mode to him down low, plus the obvious faults.

ahh, and the thought is that the automatic transmission codes are causing the limp?

Well, it certainly is throwing something off, and the calibration is all wrong anyway for an auto... |

No... but I will help you solve this if you are not done first  I don't have the car/ecu here yet. |

Sounds good. i'd like to be able to help resolve this problem for future 4.2L users.
I'll continue down my path of installing the engine in for now, i have to make some oil pan modifications before i can fire it up, but i should be able to get first fire in 4-6 weeks or so. and we can dig in further from there.
meanwhile, if there is anything i can do before i have the engine in and stock electronics wired up, i'm all ears.
