This is the table I get from KFTVSA, the values look fine, but I wanna confirm they are with you guys

Fits:
It is stock KFTVSA of 018AB-TT  dump

Quote
I changed the value to 2.5500 at 2000 - 6600 RPM (on the bottom row, 80.25 C) but its not doing anything on decel

Does it work, when you press clutch ?
Then you missed CWSAWE

Went out today and kept eye on the fueling side in VCDS. Im sure my KFTVSA is wrong since its not waiting for fuel cutoff, its going straight to 0.

So I put those values back to stock.

With CWSAWE changed to "1" I get nasty bangs on downshifts, sounds amazing.

I think for getting the burbles on decel I need the correct map for KFTVSA. After that I can fine tune how loud and when I want the burbles.

3 = Delay always active, no fuel cutoff during NOx-catalyst regeneration
2 = Delay activated only when clutch depressed, no fuel cutoff during NOx-catalyst regeneration
1 = Delay always active
0 = Delay active only when clutch depressed

hi, did anyone manage to make a good working pops and bangs program for this 8N0906018AB? I've tried and at best I get a bang "every now and then", but it seems to be somehow temperature (catalysator?? not sure) dependent, in some situations I get a bang, in others not. Is it necessary to touch, for example, TATMSA, TKATSA, TKATW, TKATMN? Raising TATMSA over what I see tkat in logs, didnt work. Fuel flow is dropped usually very shortly (like 200ms, instead of what is put in KFTVSA) after liftoff.

YES..

Somehow other than removing fuel cut completely? could I see what changes have been made and where? Is it possible to keep the fuel cut but just increase the delay in a functional way? KFTVSA just doesnt work all the time...It's like there is something interfering and the funktionrahmen does not correspond to the function in this ecu.

Is there any way to remove remove fuel cut only from high rpm or from a certain high rpm area? For example, more than 3500+ no fuel cut.


I got the car to bang from the ac button, it's easy, but I don't like the idea that it has to be summer and that the engine brake is reduced at all revs.

KFTVSA really doesn't seem to work with this.

I tried playing with TKATSA and TATMSA but that doesn't work either (tatmsa doesn't affect tkat). (Plan was to use tkat temperature to prevent cutting off the fuel supply.)

I got pretty nice upshift / throttle release popcorns with:

2500-6520 range
KWZWMN rows 15-24: -37,50 & row 50 -29
KFZWOP rows 4.99-19.99: ~28
KFZW first row: ~27
KFLBTS rows 25.50-49.50 taper from lambda 0.95 to 0.85 (3500-6520 rpm)
CWSAWE 1 (may not be necessary, didn't confirm)


However, I reverted back to stock because broke already 2 front lambda-sensors. (the incorrect placement in the aftermarket dp is partly affected). End of play, this is very stupid Cheesy

1 = Delay always active
0 = Delay active only when clutch depressed

that is interesting. I have never heard of a NOx catalyst on the 1.8T's. My BMW from 08 happens to have one, and im not a fan of  those.. but still weird the ME7.5 has some programming for NOx sensors..
