2005 1.8t man Qttr A4. Stock motor, garret GT2554, GTI 318cc injectors. As I have dialed in my KFMOIP & related load tables, I have lost Fueling enrichment requests, it appears, according to logs.
Logs are showing constant 14.7 requested despite WOT pulls. I tried utilizing the KR based fueling, which seemed to have no affect on the fueling, again, according to logs. Not sure what has happened within the tune, or maybe I am logging improper values.
Sure would appreciate some suggestions to re-enable fueling enrichment.
I plan very soon to install larger injectors, as these 318cc's have me limited atm.
Thanks for any input or opinions!
A few logs and tunes attached.

TABGBTS ?
You dont log that parameter so not sure if its active. Do you use BTS or LAMFAW for your WOT fueling?
Also a definition for the bin would be nice

Right. I'll include my xdf.
I have been using Lamfaw for fueling, which seemed to work well until very recently.
When I suddenly ran in to 0 enrichment request, I have investigated further, and feel that KR enrichment seems like a really good method of enrichment. BTS also seems like a good method.
I tried to implement the KR methed, but logs have not changed.
I'll be sure to include TAGBTS in my lgging, Thank you for having a look, greatly appreciated!

I'm thinking maybe my MAP sensor has gone bad?

Am I not reading the log properly..?
According to the log(s), from what I'm seeing, car is requesting 14.7, while my tune should be requesting enrichment upon increasing load and boost. But from what I can see... its maintaining stoic.

Changed the MAP, new bosch unit, problem persists. Could it be my KFMIOP/KFMIRL relationship?

To rule out hardware, I flashed with a new base tune, I had used long ago.
Fueling seems to follow request reasonably, and it no longer persists 14.7 request.
I did log a short 2nd gear run, which had no major hiccups.
Thank you for having a look, I did log the parameters you suggested.
In order to resolve the issue on the previous tune, I could flash it back and see if i'm able to find the error within the tune.
It may help others.
Here is the log of the new tune, and the tune itself.
Thank you btw for your input!
I do want to make KFLAMKRL my base fueling peramiter, as that seems to be the best method, (IMHO) from reading the topic Julex had researched and brought to the community.

Not sure why lamfawkr isn't taking over, would need to look at the FR again.
in any case
* bts isn't richer than lamfa
* requested fuel is clearly following lamfa
* you are requesting way too much timing, have too much boost, or are running very bad fuel

Thanks Nyet, for having a look and suggestions. I'm injector limited right now, so have pulled back some timing, as asking for more fuel wont result in getting much..lol
And yes, fuel is only 91oct. Definetely not the greatest.
I plan to install some larger injectors very soon.
