I have a Problem with pop & bang via A/C Button

I have changed the following areas

CWSAWE  1
DNWEK    7000
KFZWMN  first two to -18
KFZW2     first two to -18

This isn't working.. no Pops Undecided

Have i to change any value in KFTVSA and KFNWEGM?

Btw the A/C won't work. The System has no gas inside.

Look around... I just recently wrote about this. If you want pops and bangs on overrun, this is what I do:
KFTVSA --> where you want it to happen 2.5s , and then modify the lowest load line of KFZWOP1&2  -22degrees, KFZWMN -31, KFZWMS -96, from 4000rpm to 6000.

No need to modify KFZW or KFZW2 for pops.

That will give you nice pops on overrrun down to 4000rpm

so i got it . but it should pop via A/C Button. Here in Germany the cops are very terrible with something like that..  Have you any idea how to get this job done on A/C Button?

Use KFZWMN and KFZWOP. TVSAG0 for completion.

If you only want it to pop on AC set DNWEK to 6000 and leave KFTVSA stock or even set to 0. Then it won't pop ever with AC off.

If you fear getting pulled over then you shouldn't do pops on overrun, which isn't illegal btw, but you should have a certified/homologated exhaust.

Hi Guys, I have a 1m AUQ Stage 2 Leon and I want to add the pop and bang with A/C but keep getting checksum issues.

I have no idea how to resolve this, as I am new to all this. Is it possible for someone to add loud pop and bang via A/C for me please?

Thank you!

This solution works like a charm for putting it under the AC function. Tested it just now Smiley
Thanks for the information much appreciated!

Kind Regards.

Here in Denmark it’s illegal so would also guess it’s illegal in Germany too (:

-Unnecessary noise (same as with wheelspin) and if you do real pops it’s also over the noise limit.
-Removing the CAT will put you in risk of Emmision fraud (heavy fines, never seen any tho)

Have seen people get fines for pops here in Denmark (:

You want some tuning with that pop and bang?
-Nahh it’s not good for the engine

Apparently Denmark is supposed to be the second happiest place in the world.  I’m wondering why.    Huh

Yes

Okay, so I am wrong with something.
I tried to set dnwek to 6000, kftvsa was stock (I also tried to zero for all columns - result was same), tvsag0 to 2.5 and it still pops for all the time.
It didn't matter if I used A/C or not.

DNWEK is added to KFNWEGM. Which means there never will be fuel cut if AC is on. (If DNWEK is over 6000).

Have you left KFNWEGM stock? It's also true this method doesn't work perfectly. Sometimes a pop or two slip through before fuel is actually cut I suppose.
