Symptom - after getting the i-limit set up perfectly, after a while, the car starts overboosting. Clear codes and reset adaptation, overboost goes away. Problem? It appears as though the i-limit adaptation is a drunkards walk - i.e. it ONLY adapts upwards, since the MAP limit prevents the adaptation function from seeing an overboost large enough to cause a negative adaptation. Opinions on best way to fix? Don't say openloop WGDC, thanks

I'm guessing reduce LDEIAU and TLDIAN?

Or, alternately, disable upregulation completely? might be safest...

Fix the scaling in the ECU and run a big enough MAP sensor

Stop guessing, log. gonna need a WHOLE lot more ram variables How much of the ldr i-limit adaptation path can you find for me

hmm:
ldimxr_w ldimxrk_w
B_ldimxp B_ldimxa B_ldipos
B_ldimxn? B_ldimxp? B_stldw? B_stldia?
(?) not sure if needed
or anything else you think i need for i-limit adaptation?

Here is what I ended up doing:
First, tried shifting TLDIAPN (RPM is based on k03 spool, so it is pretty aggressive at low rpm) bad news, no matter how far I go out, any persistent lde will result in adaptation. So if you have a stock DSLOFS, and are running past the MAP limit, good luck; the ECU will keep adding I limit forever, since MAP limit is always under requested.
So I chose to nuke it entirely by setting LDEIAP to max (1270) on a locked WG RS6 turbo file (it is locked via KFLDIMX, not KFLDRL)
It is worth noting that stock LDEIAP is actually negative (-20), so even if you aren't over boosting, positive adaptation is enabled.
I'm not quite sure what my approach is going to be for my car (DSLOFS=0)... since really I just want to numb positive adaptation, not completely kill it..

Also, for debugging negative adaptation, I'd need B_ldimxn ... I hope you're still reading phila
