ENSAKHG is a config bit. And I think I set it to 63 to allow overrun in all situations.
NGDNSA is set to -5120 or thereabouts:)

Sorry, but asking this to clarify Tongue

With NGDNSA am i correct in thinking that it'll cut fuel below 5120rpm on over run?

If so then that seems a better way to do it rather than using kftvsakat as I am now to disable over run fuelling below a certain rpm.

As I understand it, it is the speed gradient (RPM/s) where fuel is cut off.
As in if you decelerate at with 5120 RPM/s (hence -5120), fuel is cut off.
Anything above that, fuel is on.

My KFNWEGM looks like this, I think the first two rows with the Values 100000.0 are wrong ?
Has anyone a Picture from his KFNWEGM that I can compare it to mine ?
I think the Map is not assigned properly in my XDF.






Edit:

And has anyone found a possibility to put that gargeling on and off by pushing a special Button in the Car ?

Edit2:

So I flashed my ECU with the changes in the following Picture.


But it dosent bang between shifting, it only bangs sometimes when I am in Overrun but only when I hit the gas shortly.
With 37.5 degree it is the same, so I put it a littlebit back.

Now I am not sure If I should test it with more Fuel (look at Lamfa at lowest line in the Picture).
But I think the Problem is like somebody wrote earlier in this thread, that there is not enought Air that the fuel can not explode.

Read the thread again. Seems like you missed a lot of important things.

I read the whole thread again.
The problem is, everybody do different stuff and for some engines it works for some not.

But I think I disable it again, my Cats would be glad about it!

First of KFZW shouldn't be changed and your LAMFA axis looks funky.
And your changes in LAMFA isn't needed, they do not apply on overrun.
And the whole KFNWEGM thing, I still dont get why people use that way.
But yeah, your KFNWEGM doesn't look right.

Me7 has a hard limit at -25° ignition, so anything below that won't make a difference.

How do you stop the revs from hanging during shifting?

@birchbark506
Are you shure there is no highly positive angle in KFZWMN? This is something that could cause this.

@KasperH
In my case, I was able to remove that limit by modifying KFZWOP. There is a delta between KFZWMN and KFZWOP which didn't exist in earlier ME versions (like 1.5.5).

Are you referring to the negative timing limit?
No way around it, its hardcoded.

Yes, but in my case it works. Was logging this and angle goes down to -40° when deccelerating. Bangs are loud as well. No problems with this since i changed KFZWOP.

How would I log just when I shift it takes about 2 to 4 sec before I can let clutch out to grab next gear, if I shift to fast it's to high rpm to shift
