Yes I know, I wanted to double check my map and see if I have it correct, I got the pops but nothing like his video

Why not post up what you've changed?

It works different on different engines and ECUs of course they have different operations sometimes. However changing KFZWOP is important since the kfzwm chases kfzwop and if kfzwop is too high the pops and very low because kfzwm will go after kfzwop and go positive.

Is overrun only possible on turbocharged cars?

Is it possible on 4 speed auto cars?

I'm trying to figure out if it's possible for a 2.0L 8v engine.

I've attached my bin below, if anyone has any map locations or a full xdf, It would be greatly appreciated. Thank you

For people who can't find CWSAWE, here is a trick. Go into a bin editor like 010 Editor, search for component nr in ASCII search mode and search for 20vt. Then just 1 or 2 lines under the component nr of your engine the first 00 or 01 will be your CWSAWE, usually 2nd or 4th column. Enjoy.

From MED 17 PDF FR:

U¨ ber das interne Codewort CWSAWE kann die Funktion konfiguriert werden:
+---+---+---+---+---+---+---+---+
Bit-Nr.: | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
+---+---+---+---+---+-+-+-+-+-+-+
| | | | |
| | | | +---------------------> 0 = Schubabschalten wird nur bei B_kuppl = 1 verz¨ogert
| | | | 1 = Schubabschalten wird immer verz¨ogert
| | | |
| | | +-------------------------> 0 = B_denox sperrt Schubabschalten nicht
| | | 1 = B_denox sperrt Schubabschalten
| | |
| | +-----------------------------> 0 = B_desu sperrt Schubabschalten nicht
| | 1 = B_desu sperrt Schubabschalten
| |
| +---------------------------------> 0 = B_dsls sperrt Schubabschalten nicht
| 1 = B_dsls sperrt Schubabschalten
|
+-------------------------------------> wird in %MDFAFI verwendet

U¨ ber die Bitmaske ENSAKHG kann die Freigabe der Schubabschaltung bei Katheizen gangabha¨ngig gewa¨hlt werden
+---+---+---+---+---+---+---+---+
Bit-Nr,: | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
+---+---+-+-+-+-+-+-+-+-+-+-+-+-+
| | | | | |
| | | | | +---------------------> 0 = Sperre Schubabschalten bei Katheizen im Leerlauf
| | | | | 1 = Freigabe Schubabschalten bei Katheizen im Leerlauf
| | | | |
| | | | +-------------------------> 0 = Sperre Schubabschalten bei Katheizen im ersten Gang
| | | | 1 = Freigabe Schubabschalten bei Katheizen im ersten Gang
| | | |
+---+---+---+-----------------------------> 0 = Sperre Schubabschalten bei Katheizen im x-ten Gang
1 = Freigabe Schubabschalten bei Katheizen im x-ten Gang
Default: ENSAKHG = 63



Good Evening,

can anybody explain, what B_dsls and B_desu stand for? I don't have the FR for MED17.

My Goal is to Map Pop&Burble on AC by using the delta RPM trick, but it does not work. Since CWSAWE=32 worked on DSG Cars, these bit switches mustn't be necessary for my target, a manual car. Don't want to try it without knowing what it will affect or what they are used for.

Thanks in Advance!

After some further search on Google, i found out that B_dsls stands for "diagnose sekundärluftsyttem" means secondary air system diagnosis active and B_desu is a request for regeneration of NOx-Cat. Just in Case anybody else is wondering about the same question.

NOx-Cats and Secondary Air System are not installed (Euro 4 Car). Anyway, even if they were, B_dsls and B_desu would not be requested all the time (i guess) so Bit 5 is "%MDFAFI" but seems to be the key difference in my opinion. If i find out what this bit it affects, i will have another try and report.

I've been playing with this the last few days and now bored of bangs.

I want flames.  Lots of flames.  Minimum ignition angle is -24 and ZWOUT follows during lift off.  Lambda actual goes lean (+1.4) but requested is 0.93 (from lamfa).  After about 1000rpm (from say 6500 engine braking to 5500), injector pulse width lifts to >2.0ms and lambda drops to overshoot requested.

I brought TEMIN up to 2.0ms but it's caused cruise to be 10:1 obviously.  

I think I'm getting confused and can't really find concrete evidence on what creates lift off flames.  You need fuel; but I'm unsure how dump fuel on lift.  Not sure if -24 is enough.  I've walked around various numbers but not really found a sweet spot yet.  Rich?  Lean?  More advance?  Less?  Table tops at -96.

Change variable cam tables so you have lots of overlap on overrun.

Hi guys,

i'm currently working on pops / bangs on a Corsa D OPC / VXR with ME7.
- I lowered ZWMIN to -50° everywhere
- KFTVSA & TVSARL to 2.5s everywhere
- NWENG & KFNWEGM to 0rpm everywhere
- I set CWSAWE to 1
- Tried to disable the Tip-In functionality
- Raised FWET & FWEHT by 0.5 everywhere

Got this running on an Astra G / mk4 Z20LET by simply changing ZWMIN. Not working on this corsa.

Just a little bit of gargle. I'm guessing there is too less fuel, maybe because of these small injectors. So what are your guesses and how to raise the fule amount?
Was thinking about using LAMFA for this.

Cheers
