@n14

Ive been reading the whole thread the past few days, so i know what you mean, but: The name of this map is called "Wiedereinsetzkennfeld" in german so its the rpm at which the engine starts to re-fuel after SA fuel-cut, right? If it is, wouldn't it be right then to set it to 0?

Additionally, i tried setting it to 7000, but also no effect on the corsa. Normally I'm working with -40, as in my astra, but as this didn't seem to work, ive been trying this out.

My guess is, that, probably not only in my case, the Tip-In affects the ZWMIN with the ZWSPAE. I tried to overrun this by simply setting everything in ZWSPAE to -40° but the gargles are only getting a little bit louder. Measured with an obd-reader and its -30° when deccelerating. So the angle is late enough. Thats why I'm thinking LAMFA is the right choice.

Am I wrong? I attached an Image of the LAMFA map. Is there anything wrong? like too little injection or so? LAMFA is original currently. Was planning to set first row to 1.

Are you German, Ulf?

From my point of View "Wiedereinsetzdrehzahlkennfeld" means the RPM Tresholds wenn ECU starts to Inject and combust again after the engine speed dropped. For Example:
When you accelerate until lets say till 5k RPM and you press Clutch and release the gas pedal, the engine speed drops while (after some amount of time, defined by KFTVSA and some other influences) overrun cut is activated. When the engine speed lowers under the RPM given in KFNWEGM, overrun cut is deactivated again.
In German you would say " Es kommt zum Wiedereinsetzen der Verbrennung".

I think, if you set this value to zero, you will never force to disable the overrun cut, while if you set it to rev limit rpm, overrun cut is always disabled because you always stay underneath the threshold for "Wiedereinsetzen".

I can't help you with the other Questions, sorry.

For clarity:

I just changed my username to opctim. ulf91 is a name ive been using for years for a reason I don't quite remember, so i guess its time for a change.

From my opinion you also should at least try more earlier angles, like -20°. Angles from -18 until -22° work good on Mini Cooper S R56, for example, other users had something around -20, -25°.
Of course TFSI,BMW and OPC engines are barely comparable, but they are both small package concepts with short exhaust manifolds and the cat directly behind the Turbocharger. From my understanding, for Pop&Burble you need enough combustable Fuel/Air-Mixture at the right place in the exhaust system.

I don't know which engine you are driving in the Astra, and i hope i don't get you nerve while writing this another time, but you might give earlier angles a try.

I'm playing with KFKHFM and KFLF just now.  Going to try bumping KFLF UP to see if that'll put more in.

I tried cam switching too; AFR now goes super lean on lift (which makes me think it's now getting air) as before it was just going rich but still no flames.  So I'll add a bunch of fuel in with KFLF.

Timing values, I'm still undecided on too.  -30 at the limiter sees good flames but could be better I think.  Overrun wise I'm struggling, can't find that perfect spot yet.  Currently at -27 tapering down to -21 as the revs come down near 3000.

The corsa already has a 3" pipe. Pre-Cat removed. Main-Cat still in place. My astra is also banging with cat installed and 2,5" pipe.

I'm trying.  I need to get out and log.  It's too warm just now (32 degrees), so I'm drinking rather than logging.
