Hey,

I strumple though forum and Funktionsrahmen, but I am not sure to unterstand it correct. Maybe some of you can give me a hint or support:

I like to chance TippIn behaviour of my 8N0906018Q Audi TT software. There should be a bit more enrichtement. because AFR requenst is on 0.92 at WOT.

As I unterstand LAMFA is the map, witch covers the tippIn behaviour, but the map in this software is a bit strange applicated, because x-axsis is a mishmash from 0 to 160 to 70 %, like it seems in some software.

Reading in Funktionsrahmen, LAMFA is only active, when driver requests maximum torque via mrfa_w. Ok, in my case LAMFA will be active, when driver requests 400Nm of indicated troque (100 %MDI of 400Nm).
LAMFA is  map of 6 x 15, where the x-axsis got 6 rows and there diffinition is MRFA_W.

But this doesn´t make sense all to me, because if LAMFA is only active, when MRFA_W is at 100%, a line instate of a map will be enought.

So, to have a TippIn enrichtment I only need to low values of the 0% row, or does it make sense to sort the x-axsis e.g. to 50, 70, 90, 100, 110% and set the requested value right on the 100% row ?

Thanks for advice
Jochen

ok, but what does this mean to me ?

How do I manage a TippIn enrichmend ?

When I log, I see 0.92 when I pressed full throttle, so the enrichtment request was done.
These values you´ll find a the 0% row on the stock map...

Do I just need to chance this values to 0.87 e.g. to have an enrichtment ?

What Adam means is you need to add 1 space to the second axis (mrfa_w) start adress. So if it was for example 10ABC you change it to 10ABD. Dont change the axis values before you have corrected this, you'll understand why  Smiley

Thanks, that the info I need   Cheesy

Yes, now it´s clear for me too

First row covers all requested torques up to 160%MDI, so at all possible.
In this case, I got my caracteristic line, I expact

You dont need over 100% on the mrfa_w axis, that is the maximum value from that variable.
