What is the relation between those maps?
Silentbob said that KFZWOP, KFZWOP2 maps are used for best Power.
Advance timing is eddited in KFZW,KFZW2.
My question is:
How do i relate those maps to each other.
The car is RS4 B5 - E85 - 551K box.

KFZW is desired ignition angle.
KFZWOP is the ignition angle that would produce the most torque in that engine if you weren't knock limited.
Basically, the ecu looks at the current ignition angle, compares it to KFZWOP and determines what percent of possible torque the engine is producing.

Great, Thanx D. Looking at logs, my actual timing has higher values, than all of those maps. I understand that depends on iats, pressure.... Does this mean that I have to edit my desired KFZW to get closer valuse to WOP? What do I make of it? I feel I need to ask those questions, bc I have been Reading alot and have not found any reasonable explanations. |

Honestly, your tuner know's what he's doing. It's unwise to think you understand someones work well enough to make modifications to it. I'd probably start fresh if you're interested in these things  |

I'd probably start fresh if you're interested in these things Well, I`v said this Before: Nobody remembers a chicken Well I did sort my boost Control and nasty TC I had. I do not have a tuner as I see it. The one that is newer answering, could not care less. It is my car, trust me I am taking baby steps. And if it brakes, F..k it. I just build better. I am not kind of guy that gets scared and backs off as soon it gets hard. I will learn this, trust me. Besides, there is really not much material here on RS4, it benefits this forum |

ALL of this applies to the rs4: http://s4wiki.com/wiki/TuningHeck, this whole forum was started with the s4/rs4 in mind. |

KFZWOP(2) is only used in intervention and torque calculation. It is ignition angle for optimum torque at lambda 1.
These tables dont need to be touched unless you've converted to a different fuel.
Your logged zwout values exceed zwop values on pump fuel?

For clarification, the OP is referring to an RS4 running E85 tuned by PRJ.

Definitely relevant information. In general, my advice is to not worry about the ZWOP tables. If you experience undesirable intervention from poor ignition angle efficiency (won't happen in your case), then tune the intervention i.e. dlambts. |

Touching KFZWOP is completely pointless on this car. It's not needed for pretty much anything, as the car always runs 100% angle efficiency anyway. There is never ever going to be a single knock event regardless. I was sick with 39C fever for some time, thus I've got a little behind on my e-mail, but going through it and answering everything I omitted, so Kemo, don't be so pissed off and check your e-mail! Boost overshoot on this car was due to leaks present when mapping, thus once they were fixed it overshot some. Still made 2.6 FATS though It's running a 5120 RS4 and the car runs fine. |

Well, i am not pissed off at all - check your email. This what i am doing has nothing to do with your work. Your job was done! The car runs great and best recorded fats now is 2.45. 100-200 7.6 sec and i am not a fast gear shifter |

Did not touch ZWOP tables at all. Made some slight changes in KFZW/2 after peak load up to top. Just wanted to here what you guys have to say about this. No intervention - nothing strange at all. The car rips as hell all the way. There is more to get here |

I have read Wiki like 30 times now. . This is a very complex thing. Well it is not the whole truth seeing it from a newbie perspektive. I mean if you take an S4 551M box. There is straight forward tons of info and examples to read and follow and apply. A lot of that can be used on Rs4 as well - if you know what your are looking for. That is the problem being newbie. You dont know this! What do you do? You type in RS4 or 551K or something similar and search. All the tables are not the same. There is not as much straight forward info. I feel it is appropriate to ask all the questions. There is allways some benefit of that even if it feels stupid for you regulars . |
