I think, if you have the cf´s high, with scaling the axis like this without changing the ign angle, you will get more probs.
I would have taken at least the same vales for the same load as before and for the 12ish load, build a complete new retarded ign. angle row.
There you could log and test if this worked, without any danger.

when you change axis values.. yes, you will have a more probs... but against values higher than original values.. Can you please look at my attachment. @ 6ms engine load x 5000rpm.. Old ignition angel = 29.25 new ignition angel is 36 !! Automatically i will see advanced timing all over the place...approximately 7 degrees  But lastest maximum engine load values same as original KFZW.i think we should be reduced middle load rpm timing area.. i'm not sure for this changes... Do you have tried this before on motronic m38x ? |

Oh, correction: This is what I meant. By changing the axis data, the ignition will be much too advanced. You have to change / bring them into the right place again... So you should divide all values through 1.2, and then you should be at the same level as before. After that you change the timig after you logged again, if necessary. @ all others, correct me if im wrong. Didnt try this yet  |

So you should divide all values through 1.2 Pro tuning  Sorry, I just found it funny. I think a bit more work needs to be done than this  |

I didnt say it would solve all his probs with cf.
But after changing axis, he will get by doing this, to the point he was before.
But with the advantage, to have a better resolution.
Or do you mean, that axis changing generally doesnt work on here?

Hi PRJ,
Reading your posts, gives me the idea that your have worked on this kinda ecu before.
I have a small question related to the topic.
Is it correct that this map (screenshot) is responsible for the main/fullthrottle ingition and needs (also)tuning to sort the issue ?
Thanks for your efford,
Cheers,
PvL

your load axis looks very different to what I see..
sure its right?
I have 10-150 on a 150bhp AUM Golf engine in comparison

If only I could remember. I tuned this long ago and I was finding the maps by hand without DAMOS. But M3.x is very similar to old Motronic (M2.x, M1.x) the main difference is that it has a 16 bit MCU. |

Yes, that is the correct map for ignition angle, there are probably one or two more next to it that should be tuned initially to see which one responds. You shouldn't be changing the load axis unless you are exceeding 10ms/stroke of load. Rick |
