Title: TippIn enrichtment and LAMFA application
Post by: jochen_145 on May 07, 2018, 03:12:39 AM
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  :)

Thanks, that the info I need   :D

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.
