Arthur, all arguments aside, why don't you simply go and fill your car up with 87 AKI fuel and report back here?.

That's fair.

That's fair.

It is fair...but don't expect a clear or indeed honest answer from the high and mighty one.

I'm curious, because the Audi DSG gearbox, for instance, uses fuzzy logic to adapt its shifting to your driving style.

Do we know that the algorithms that control ignition don't employ some fuzzy logic i.e., are they not also adaptive?

I'd be surprised if they weren't clever enough these days to be able to cope with the octane variability themselves? Maybe Mihnea can advise?

Thus the CF's that throw a CEL will be changing all the time.

Run 99RON and your achieved timing will be ~A degrees of advance. The ECU sees this and sets the map limit to X.

Now run 91RON and your achieved timing will be ~B degrees of advance. The ECU sees this and gradually reduces the map limit from X to Y.

Result?

No CEL's.

Easy to implement.

The obvious question is, if timing isn't being pulled as a result of carbon, what is it being pulled for?

I'm not going to risk pitting my pistons to prove something I know to be true...
I must be crazy for trying to participate in this self-serving, self-pity, negativism...
I get paid >$125/hr by clients paying a lot more for my consult...I should be more selective with my time...
got a 2+ year back log, actually wrote microprocessor based code (same processor as the RS4 ECU utilizes), was told I was one of the best, on any machine...the code is easy, grasp of process optimization, not so...
and yet, I get BS, re: high & mighty one, from dufus's like karl...nice contribution btw...

this site has deteriorted rapidly since sims (and his ilk) has arrived...it's all belly-aching and no facts, no information, just a message of doom...
boo, hoo, my 400 HP sports saloon doesn't make 400 HP, oh woe is me, self pity...over a dang 'object'!
it would be laughable if not so pathetic, lol, and yet, I chuckle...

these forums used to be a positive atmosphere, but have morphed into a 'crying room' for folks no want apparently want to listen to in the 'real world'...

your approach is all wrong:
if I felt I had been 'wronged' by Audi (or any entity), I'd go silent, I'd go deep, and deal with this quietly and directly...and I would prevail...whining and moaning on here won't do squat...suck it up, and do something about it, I'm not the root cause of your 'issues' (I doubt Audi, deposits, over-rated HP are either, but that's another story ) so 'proving' me 'wrong' won't get you anything or anywhere, although you think you may garner internet 'face', relax, you can have it, I yeild that to you, it's worthless, let's share the nothing...

it'a all very amusing

[ArthurPE]

It is fair...but don't expect a clear or indeed honest answer from the high and mighty one.

not being 'clear' can easily mean you don't 'understand'

if you are calling me a liar (not honest) you are way out of line...
you talk a good game, but you offer nothing to the discussion...

And I do think YOU are misinforming people intentionally, and that you don't know what you're talking about, yet make it look like you know it all. I know it's hard to accept to be taught by someone younger than you are, however, I'm only trying to make you understand that Audi engine management systems are what I breathe day in day out because they are my job and also my hobby. Please stop talking nonsense and accept to learn where you don't know what you're talking about, or stop posting here, because your obvious lack of knowledge of Audi Bosch MED9 engine management systems is plain annoying.

I have no vested interest, you want to sell people things to solve these 'issues'...

you have no theoretical or practical knowledge of any of these systems...
I wouldn't let you fuel my car, let alone 'tune' it...
I know you have to try to act as if you know something, but if this is your 'business', you better start looking for another line of work...

You have no clue what you're talking about, as usual...

MED91/5/ that's what a B7 RS4 ECU is but you don't even know that and think it's a MED9.1.1 which doesn't even exist

Please allow me to laugh at your comments. Yes I have no clue, I don't have ANY practical knowledge, yet I have managed to get 7/800+ crank PS out of B5 RS4s and also 400+ crank out of a 2.0 TFSI mk5 golf GTI, but yeah Arthur, I have no clue and no practical knowledge. Yeah right.

it all depends on your perspective, some would call it a 'candid observation delivered without tact'

you better tell Audi (Bosch) a MED 9.1.1 doesn't exist...they may be up to 9.1.3 by now...
item 108 http://www.unitronic.pl/Bdmlist.pdf
uses an industry standard Motorola microprocessor, similar to that used in many A-B or Siemens PLC's (programmable logic controller, an industrial control computer, monitors/controls I/O, just like a car's ECU, go figure)
notice how they almost ALL use the same microprocessor? Siemens, Bosch, Marelli, etc....

laugh away
yes, I am correct, 'right' is a directional reference...

now, if you, as a young 'know it all whippersnapper, would just listen and learn (you have 2 ears and only 1 mouth for a reason) perhaps you could gain something out of this rather than making me just another guy who ignores you...

truce or not, up to you
you take me for an idiot, you are sadly mistaken

Art, you've never looked at one SINGLE file ever coming from a B7 RS4 so why keep this ridiculous game going? I don't take you for an idiot. I give up on you, I have already wasted wayyyy too much time trying to make you THINK in a different way but you know better. Sorry, but no one should argue with fools.

Bet he can't do a simple short reply to you.

No further on then about the OP's original subject?

He will be at the Kent meet tomorrow. so will be interesting to see how he is getting on with the car

[SR71]

Just in case anyone wants to look at a VAGCOM file that illustrates the above, I include one below.

Arthur, you do yourself no favours by blaming me when you don't want to provide relevant information/answers. Next you will be blaming me for the Ash cloud & the oil spill.

You left the forum once before for the same reason but could not do without this oxygen despite your protestations about how busy you are etc etc. I also find it odd you post so much personal data on this forum, and I wonder why.... You accuse people of lying and much more, but cannot handle it when people doubt & question you. And let's be truthful, there are many other forums you are not welcome on although you have good engineering experience. That's sad.

..these forums used to be a positive atmosphere..
...

The reality is that this forum had a positive atmosphere before either of us got here. And before the carbon got deeply embedded.

So how about we make a deal for the greater good of the forum - both of us stop posting on this forum.

Win-win.

[2manytoys]

It's a shame, I read a few forums, and the very good threads turn to mush when Arthur comes on. It's as if he wants the "Arthur Buildup" to cloud the real issue, maybe with the hope the mods with close all the carbon threads??

I think people come on here to share their experiances and ask questions. All I read from Arthur is Carbon is not a problem and do a 3000-8000 rpm run. Nothing is ever offered with respect to helping people. All the forums are the same as soon as he posts.

I can't understand why he doesn't help those that have experianced the problem? Maybe this video expains it: http://www.inspiredobjective.com/Audi

Anyway, back on topic, my car ran 9-13 degrees timing with carbon and never set a fault code. It's now runing about 19-22 (when 25C) and still no codes. It should be 30 degrees timing (as per the above attachment, and from another forum). It'll be in to Audi next week to check this out (yes, they have agreed there is a problem)
