Go to the S4 wiki, hit ctrl F and put in IMX, then you're there. Its the I limit of the PID, dropping the limit will help with the overshoot

Ok, so little confused, LDIATA is pretty much the same in every box.
I cant find a KFLDIMX, LDRQ1ST, KFLDRQ2 or DSLOFS in my bin? Its highly likely im being daft, but I cant adjust parameters I cant find.
Will increasing KFLDHBN help my overboost issue?

I've just read on another thread LDIATA should be set to 0?
I have already set KFTARX all to 1.

None of that will help if your IMX is bad.

So far ive kinda followed/ understood whats going on and what adjustments change influence what, but this IMX bit is confusing me. I can’t find most of the parameters listed to adjust? Can you point me in the right direction, looking at the s4 wiki, I should have a flat KFLDIMX, I cant find this? or these paramters KFLDIMX, LDRQ1ST, KFLDRQ2 or DSLOFS ?? Have the above parameters been renamed in vw or aum bins? |

No, you should have the proper KFLDIMX for your car. |

Ok, changing the xdf file I was using has given me access to a whole lot more parameters....so I can now see KFLDIMX, which is a good start.
My boost seems to follow requested and actual for most of the pull just between 2.5 - 3 I want to bring the spike closer to requested, how biga change should I make to noticeable changes? Should I bring all the highlighted cells down by 1,10? and bringing the figures down will help with boost overshoot, increasing the figures will help with a lower actual against requested?
I have managed to get my AFR to follow a smoother ramp, but I think I need to check my timing.

FKKVS - what is the x axis in relation to goes from 0.9 to 19?
The wiki says FKKVS is flat in stock, mine is all over the place?

Injector pulse width in ms. Depends on what car the file is from. Remember that s4wiki is made for ME7.1 and S4. But since and ME7.5 is pretty much the same, most of it can be carried over to 1.8T |

Hhhhmmmm ok, without sounding stupid so how do I adjust the table to compensate/adjust rich or lean areas.
Reduce the figures, to increase fuel in given rpm row, but how do I know which column to increase? or do i increase the whole row?

You tell us. What do different cells in a column represent? |

I clearly dont know hence the question,
"Reduce the figures, to increase fuel in given rpm row, but how do I know which column to increase? or do i increase the whole row?" was me asking for a sanity check/ as I understood, if wrong please inform/guide.
I can follow that I have rpm onside, and injector pulse width in ms but I don't understand the relationship.
