Hello together.

Im having trouble finding CWSAWE.
I think it is at 0x1C5A54, could someone confirm that oder tell me where it is?

I've attached my original file.
It is a 1K0907115Q MED9.1 from a Golf 5 2.0 GTI

Thanks in advance!

Hello Friends!

I have a strange problem with a S4.
Its a Stage 3 with k04 Turbos and stuff like that. It has a G-Box which I converted to M-File.
But no matter what I try it does not pop or bang.
I changed all maps that are neccessary but there is nothing.
KFZWMN
KFTVSAG
KFNWEGM
CWSAWE

In addition i tried to flash a file from another S4 (also M-Box) that pops quite nice. But also with that file the car makes nothing!
From logs I see that the Ignition angle goes to -24° and also Injection time is still greater than 1ms so there must be fuel but maybe no spark.. But why?? Is it because of the G-Box ECU? The other S4 has a D-Box ECU but i tried the exact same file on them. I think they are hardwarewise the same or not?

File is attached if someone wants to take a look.

I have the same problem with my D-Box. It only pops if i change KFZW into negative values, but that's not what we want.

Read the thread

KFTVSA - Overrun time in seconds (max 2.55)
KFZWMN - start with perhaps -20
KFZWOP/2 start with values like 20
TVSAG0 - 2.5s

Mess around with KFZWMN and KFZWOP untill you are happy with the result.

For stand still pops TVSAG0 is needed. Don't touch KFNWEGM you'll never have fuel cut.

It's all already in this thread ...

we know that,

When you check my file you will see that I changed all these values, but there are still no sounds. On other car the exact same file works with pops, but on one particular car not.

Hmm if you have such possibility, please log pedal position on overrun in both your and your friends s4s.

Hi friends, a simple question about your experience. Pops and bangs are an effect of unburned fuel and timing retard in a hot exhaust. But my consult is how is your experience  in terms of RPM and ignition timing retard for pops or bangs? Of course every engine / platform / millage is different.
