Would just like to thank you all for posting about this. While the addresses and names weren't the same in my ecu. I was able to use what I learned from here and made it work on my allroad...     enjoy....

Hi all,

I don't achieve to make gargle sound. It only pop one time in exhaust when I let off accelerator: KFTVSA / KFVAKL were increased, KFZWMN was decreased (-37,5 between 10 and 50% of load from 2000 to 6000rpm)

Could anyone help me by posting a csv log when he let off accelerator ? My ignition timing oscillate and my throttle shut fastly;

you should have made this changes (for my car it worked with this):

cwsawe = 1
KFZWMN @ low loads ~ -20 is enough... if you decrease it to -40 you are just producing heat... thats not really good...
KFZWOP @ low loads ~ x-20...

now you should hear it (it works better when the car has operating temperature)... please take logs and improve it by yourself by changing some other maps.

Do you know if you have a clutch pedal switch? if not it's not neccessary, because cwsawe should be 1. If yes (cwsawe = 0), you have to find it, otherwise fuel is injected after off throttle only when clutch pedal switch is active (gear change when accelerating).

Unfortunately i can't help you to find it...

KFZWOP at minus values makes it really pop..  I've got it at -20 and its really loud, almost a bit too loud.

Bringing it back up a little to stop it.  But all of these changes and it'll pop between shifts and bang like fook coming down the revs.  Just the ticket!

I would not touch KFZWOP, IMHO it seems better to change KFZW maps.

So, KFZWOP or KFZW?

I can get a single pop on let off throttle, but no gargle. I've got de-cat 3" downpipe to 2.5" Miltek non-res system.

@adam- Have you got a video of what yours is like? Am I right in thinking you're an Octavia vRS owner?

Take logs. You have to decrease your zwout to the right values. an you need fuel...

So.. take a log and look at zwout and lambda (AFR) @ off throttle, then you see what happens. then take a look at the FR and understand how zwout is calculated. also take a look at BBSAWE.

If you understand this, you will get your pops. Smiley

I've used KFZWOP because I wanted to try.  I guess they're suggesting to use KFZW because WOP is optimum and you shouldn't be playing about with that unless you know what you're doing.  I'll try KFZW and get back to you.

Nah, I've got a MK4 Golf.  It's a forged 1.8t, K04-064.  About 340/350bhp just now. Smiley
