sorry, not to thread jack but this is quite on topic.
could an immo-defeat chip be soldered to the b5 s4's ecu to fake-out a rs4-based tune written to the ECU?
this would seem like a better solution than having to go into boot mode everytime to write the EEPROM.
am i correct here? i think i may be.

Once you flash an immo-defeated bin to the 95040, you never have to touch it again. There is no need to solder an immo-defeated chip, the chip is already present, but just contains adaptations and softcoding as opposed to immobilizer data. Just flash an immo-off bin one time, and you never have to enter boot mode again (unless you want to reactivate the immo).
Once the immo is off, you can read and write without bootmode ever after. Did I get the question right?

can you help me with the terminology? what's the 95040? is that a 2nd controller in the ECU?

the 95040 is the EEPROM, which contains adaptions and immobilizer data. (atleast on me7, i dunno what typ of ECM this 4.2 engine uses). i think the best way for you to go is to source an ECU from the europeean market, as these engines came with manual transmission over here.. then just hook it up to the engine along with one of those immo-defeaters Prj mentioned.. = everything stock and 100% working. them are available over here for ~150-200$.. sais this on the cover.. "4d0907559D 0261206373 0003" i was under the impression that these engines were 5-valvers tho.. 40 valves in total.. or perhaps im looking at the wrong engine here..  (was looking at euro A6/S6 4.2) hmm.. im going to correct myself here.. there were apparently an "ABZ" 300hp 32-valver in the audi A8.. on which the ecu-cover states: "4D0907557J 0261204146/147" i dont know it this is manual or automatic tho.. on the ones i KNOW is automatic, the last letter is B,E,K,P.. this J is the only one that doesnt state if it is manual or automatic. |

are you saying that you have the ABZ ECU available for sale?
in the USA they were only with automatics, but in the past i've never had an issue running an automatic ECU on a manual setup as long as you don't give it a VSS. but i've never messed with audi before so i may be wrong.

I could definitely post a euro bin from an s8 if you wanted to switch out the OTP chip for something programmable. You would still be left buying an immo-emulator, but it would be cheaper than buying an ecu.
I was on the page where you made 1 lap before the driveline blew up when I posted I felt bad for you.

oh yeah. the first time at the track was rather disappointing. more so because one of the other drivers hamfisted the shifter on the backup car and broke the 3-4 shift gate. so that was the only lap i turned that weekend.
do we know if the S8 motor internals are the same? my only concern there is things like knock response and whatnot. i still want it to be correct.

Yes I believe so. So how do I kill the actual IMMO-code on a sample bin? Seriously, I fn hate this IMMO-nonsense. Half of the board is waiting for somebody to repair the B5 S4 / RS4 K-box & Q-box, so that we can move as a community off the M-box. Can I send you the two bin's, have you "defeat them", and then I'll try to see if I can get my car running on them? Remember, I have no-immo garbage on my car, 2000 b5 s4. |

Basically, there are 5v and 4v motors.
The 5v motors came together with ME7.
The 4v motors had M5.9.x.
The latter is what the OP has. And what he needs is 250kw S6 manual ECU with the immo defeated.
The S8 250kw manual would do too, exactly the same engine.
But it must be from a cable-throttle car.

nehalem:
Take a peak at the thread I started (understanding/retrofitting immobilizer) that's been stickied in the flashing and chipping section. There is an immo-off bin posted there already for you, but If you want me to do yours, just post it. I'll do it and post a few screenshots so you can understand the process and do it yourself next time!
prj:
Any bins that are better suited than the rest?
0261204563 4D0907557 M5.4.1 is attached below (AFAIK 96-98 from an s8).

Well S6, it's gotta be the AQJ engine.
IIRC that is a 4V engine.
The ANK is a 5V engine.
I don't know if the ECU's are directly compatible.
Failing that, there is the AKH on the S8 and the AHK on the S6 Plus.
The latter's ECU also had some sort of PLCC chip in it...

I got a price quote to get this working on a car locally as well. Will see if it leads anywhere.
ABZ swap into B3 chassis.

does anyone know the year and model range for the stock ECU for the ABZ?

Audi A8 years 94-98.. perhaps it was found in some other model aswell. seems i cannot find any ABZ engines with manual transmission over here.. i found this AKH-engine tho which suppsedly is a 4.2l 32-valver fitted to S6+ and s8.. numbers on this box with manual tranny is: 0261204760 4D0907558E not saying i have one in my hand, but quite a few of them are available over here in the 150-400$ pricerange, from breakers. |

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. |
