So, if P is fully selfadaptive and the map is only I part, so why it does not oscillate, if i write 0x0 inside? It's not exactly "I part". Writing 0 or 1 in there is calibrating it completely wrong. As to zero or 1... well what happens if you multiply by zero? And what happens if you multiply by 1? If it is the same if i use 250kpa or 300kpa sensor, why is it significantly different by me? Because you didn't scale all maps right. Have you ever measured the time response of some pressure or some other sensors? It is interesting. For example those from Motorola are also quicker than those from Bosch... Makes no difference at all, due to the way it's sampled, and I told you how it's sampled. |

I tried to write higher values into the N75 map and it seems to be better. Thanx for the Typ!
What is the difference between those three N75 maps, please? How shoud i calibrate them, then?

On 3B you have different maps for different altitude IIRC.

Thanx for the info. So if i understand correctly, the three N75 maps belong to the three pressure maps. Every pressure map has its own N75 map...
And please, tell me, i have found six ignition maps. Why so many?

Because the ECU can have coding plugs to select different maps.
And actually there are a LOT more than 6 maps to correct for ignition. You just found main maps I think.

Yes, i ment the main maps.
Can you tell me, what those coding plugs are? It is a part of the hardware? Wenn and what are those coding plugs used for?

I'm guessing to allow for different fuel grades throughout the world. |

You think, the knock control switches between the ignition maps according to the grades of fuel? |

There's only two used at a time... Knock control does not really switch maps, it works differently. |

Interresting.
End, please, how does the IDA Pro work? It disassembls the software code? How can i get the code, eventually download it from the ECU?

You bin file include the code  You have to disassemble this code and then to understand (biggest problem in the beginning). Most 8051 processors don't have a internal ROM which is used (read out is difficult but possible). |

Interresting. Thanx! It means, that in the boost chip is a software for the boost control and in the motor chip the software for the motor control...

For engine eprom yes, boost I'm not sure but I think so (I only know my S4 V8 motronic a little bit  ). |
