No reason why the S4 wiki can't be updated in parallel either I guess.
Doug, if it isn't too much trouble, PLEASE give me a heads up on specifics you find are wrong in the S4wiki. Thanks in advance, I really appreciate it. |

Nyet, you seem to be misunderstanding me. I didn't find anything wrong in the S4 wiki. In fact, it seemed to be quite a sound information source. I don't have the knowledge or experience to spot errors or omissions or else I would have corrected them myself in my own document. I don't even have knowledge of the S4 2.7 V6 biturbo; my experience is with the 1.8T BAM and BFV variant motors. The reason I sought a peer review was because I have no working knowledge of Bosch Motronic ME7.x. All I can tell you at the moment is that the professional tuner that had sight of Draft 1 commented that there were many errors, but did not give me any specific feedback. He did not say whether the errors were in the S4 wiki or my interpretation or translation of the funktionsrahmen information. That is why I am here, so that guys like Tony or anyone else with a working knowledge of Bosch Motronic ME7.x tuning can turn my draft article into a 'How To' for tuning these ECUs. Then all those with a vested interest can take away what we want for our own purposes. Yours being the S4 wiki... Does that help clear things up for you? TTQS |

...

Sorry, I didn't mean for it to come out that way. I'm just super worried that people are taking the s4wiki information as completely canonical, and I am always looking for improvements, since almost all of it predates my reading of the Funktionsrahmen and is derived not only from rudimentary logging and empirical data, but worst of all, also from "internet facts" and rumors that may or may not reflect reality  I really appreciate what you are doing, and do not want to discourage you! |

Nyet,
Please don't worry. I took the S4 wiki to be what you intended it to be, a useful, basic guide to which tuning parameters to look at on an Audi S4. In research and in a work context, I've assessed and written enough technical documents in my time to know what's solid and what should be taken with a pinch of salt.
I upped the Draft to rev 3, removed references to the previous forum I was associated with and added a table of Tony's Stage 3 tune maps but that's all for now. I sent Tony a PM to see how much progress he had made in assessing it but he's clearly busy working on his excellent software.
If we hang on in there, in a few weeks or months, we should be able to pull together a good ME7.x Tuning 'How To'. A professional/commercial tune would be nice to get hold of but I'm not sure I'm brazen enough to try to read mine!

Can't argue with that. Well, here goes nothing. [Links now replaced with attachments].
Comments welcome, but please don't savage it because it was conceived as a very basic guide for non-tuning types to get a handle on the topic (and, as I said, is based heavily on the S4 wiki) anyway. I had prepared all the material into forum free text format (many hours spent using Excel macros, etc. to format the tables) so it could be posted up once reviewed and edited.
The main document at Draft 3 in MS Word 2003 document format:

I promise to get back to work on reviewing the tuning document now. My bad for slacking off and focusing on my day job.  |

I've just had a minor league brainwave...
I used the 240 PS variant of the VAG 1.8T engine as my benchmark only because I have that in my car. Although I had a Stage 2 commercial tune on it, I couldn't read it but because the 240 PS engine is a tuned version of the 225 PS engine I used those as the 'case study' if you like.
However, it just dawned on me that the venerable VAG 1.8T makes a great example for a case study, not necessarily just because an aftermarket tune can be so successfully applied, but because there a quite a number of stock tune levels.
For example, the TT alone had 150, 180, 190, 225 and 240 PS variants, so why not compare and contrast the key maps down the power scale? Surely this would be as useful as comparing the two higher power variants with a commercial tune of 265 PS...?
Back to the drawing board!

Hi all.
Tony has kindly reviewed my 'tuning guide' document up to LAMFA. I am busy at the moment but will incorporate his comments and revise it in the next few weeks. His comments are mainly corrections rather than supplementary information, so the fundamentals won't change. However, I will change it from Draft 3 to Revision 0 so it becomes a formal issue.
I have to admit that I was made aware of Greg Banish's excellent book "Engine Management: Advanced Tuning" only relatively recently and I wish I had read it before embarking on trying to write a guide to Motronic ME 7.x tuning! I'm currently at the end of Chapter 6 "The Recipe" where cylinder wall wetting (covered in the funktionsrahmen module ESUK 9.70) is discussed. I realise now that he covers the underlying fundamental principles very well indeed, particularly with respect to ignition angle influence on peak cylinder pressure and thus BMET.
However, another fundamental that is very well covered are the subtleties of tuning for larger flow rate fuel injectors. My document at Draft 3 only refers to KRKTE but voltage compensation curves and the short pulse width phenomena need to be discussed.
Regards.
TTQS

cant wait for Tony to get going on the "How to guide" and Doug i printed out your article and will be reading it tonight. Im a total noob when it comes to software all around. I am a VW tech and have the hardware down all the way. just wanted to branch off to hopefully get it all down. Im also new to the whole Euro tuning in general. used to be a Honda guy  i know  |

I'm hoping to have the revised issue up next week. I've just translated the RKTI funktionsrahmen module into a shape I'm happy with. I was going to then trace out the various line diagrams and incorporate these an an Appendix 4 but that might take some time because of their complexity so I might just paste the JPEG images in this time round.

Only a few pages into this, and I'm already loving it. I'm a total noob, so a resource like this is invaluable. Great work!

TTQS, Thanks for taking the time to summarise and highlight the important calibration parameters for tuning a Audi TT fitted with a Bosch ME7 controller.
I read all 53 pages of your work.
Thank must have taken considerable effort!
I will reread it again as I may have some questions on certain calibratables.
Thanks for this work again.
