PRJ do you mind posting what you had in the PDVNV map stock? Trying to match it up (and see if at least one definition file is sane to copy from).
Thanks!

From a quick look in mbox code 0x11221 should be PVDNV (6x1). I have no idea if this matches what def files say. (or if you are working with 551M) |

I know its a little dusty thread, but since I am already working on the problem for some time now that the engine stalls when stopping and declutching I have some oscillations when open throttle a little and engage the clutch. I am going to check tomorrow if tweaking PVDNV is going to help out my problem.
I have a Spec stage3 sinterclutch with 4,5kg flywheel which makes it terrible to drive around when dieing at stops all the time.
(Already tried FKKVS to compensate a little fuel short on low RPM which helped already by 60% but dint solve the problem, also somebody else said solving this sort of issue with adjusting ignition time and tweaking acceleration enrichment, only ignition did something)

You need logs.
1. Log
2. Deduce what the problem is
3. Modify parameters to solve the problem
Changing things randomly is never going to solve such issues.

It is not necessarily present in every binary. Can be called something else. Basically IF you have the exact same issue you need to adjust the RPM pid controller when the car is not idle. For example this controller controls the engine RPM when the car is moving in gear with no throttle applied. Don't just search for value and add + to it without logging and finding out what the problem is. If your fueling is bad at some lower pulsewidths, it can also cause such yoyo effects... Another one that will cause random stalling with a light flywheel is when your fuel resume is set to stock values (too low). LOG LOG LOG LOG  |

I tweaked the PVDN a little rough so sometimes its going to oscilate at idle, when coming from overrun.
The biggest part of the problem is solved, if I declutch now when i just release the gas pedal it picks it right up at 1000 rpm. The only problem still remaining is when declutch at full overrun coming from above 3k rpm and let is slow down between 1250-2000 rpm, when declutched it still stalls. If I declutch above 3k rpm it will pick up as it should.
I am sure to bring the PVDN way more back because I bounched it up to much for my thoughts. However I am going to log and post it.
Here is my bin and xdf already:

What RPM is your fuel resume at? I am sure it is set too low.

What do you mean by fuel resume? Searched for it but you are the only user using this Translated it to my language but its not clear to me. |

I was finally able to log some.
I surely need to decrease PVDN a little because with a little throttle and clutching the rpm start to oscillate, but that's for later.
I cannot find the map KFNWEGM which Prj is telling and also the map BBSAWE. But I see that BBSAWE is for raising fuel cut by tester, so what is that supposed to say?
I already raised idle to 1000. Also experimented with NRLMN and NRLMNLLR which gave the result (in combination with PVDN) that it will hold steady on 1000 rpm when declutch right after closing throttle, but it sucks to drive like this and shouldn't be the way of driving.
