For 8E0909518AK_0261208230_368072 SW 0003

CWSAWE should be @ 0x11925 (this is based off conclusions with  tt 1.8 BAM ols file and address given by tjwasiak for 4B0906018CG bin)
KFZWMN_0_A @ 0x124ED
KFZWMN_1_A  @ 0x125AD
KFNWEGM_0_A  @ 0x1A242
KFNWEGM_1_A  @ 0x1A26A
KFTVSA  @ 0x1A2BA
KFVAKL_0_A & KFVAKL_1_A yet to be found

Edited


 

Thank you, I was really struggling to locate these. Have you tested out on the a4 yet, so far I've done the following and not a peep. I've got not cat and free flowing exhaust.
CWSAWE TO 1
KFZWMN -18 LOWEST TWO LOAD LINES
KFZWOP x -20

You need to adjust KFNWEGM too. Where do you think the fuel is coming from?

I was going to adjust that last night but did not find the map location. I will adjust today giving the chance now I have the location.

Thanks

I would prefer using KFTVSA over KFNWEGM.

@seany260: Probably your KFTVSA is zero all over the map.

You reduced the ignition angle in KFZWOP all over by 20? That's not a good idea...
Try only reducing the lowest load line and RPM from ~2000 to ~5500. Maybe the second lowest load line could use some reducing too (~-5°KW). But leave the rest like it was.

It should also be enough, to reduce the lowest load line of KFZWMN.

Log your data an take a look if your o2 sensor is measuring AFR of about 14.7 when you are off throttle. Also take a look @ zwist.

No no, just the lowest 2 lines of KFZWOP reduced by 20.
I'll make some edits 2night and log all the variables needed afterwards.

Many thanks for the help.

I made the changes suggested and still nothing, I have not got a log done as of yet, just tested on the way to work this morning. What are all the variables I need to log?

I take it you mean asking for help?

Ok I understand now, I don't do that purposely just being lazy and not turning caps off. Noted for future, thanks.

Do you have WB? Whats the afr during overrun?
Kfzwop should be - values?

you have to log at least:

RPM, WPED, RL, AFR (do you have wideband?), ZWOUT, ZWSPAE, ZWSOL

KFZWOP should not be negative, thats ok. Are you sure your adresse of CWSAWE is correct?

If 518AK file is being referenced, CWSAWE plausibly located at  @ 0x11926 instead. I've had to compare and test with a 518F file & map pack.

Left Side 518F <-> Right Side 518AK

I have noticed that after switching 0x01 @ 0x11926 overrun pops continue.

Yes Im wideband, and AFR is stoich, load 15%. Ive changed the address as suggested by  'BlkSerialKilla' (thanks for the correction btw) but still no pops or bangs because what I can see from finally getting a log done is that,
Ignition angle is following 'zwsol' when there is fuel on lift off but is stopped from going lower because instead its limited by 'zwspae' on overrun and looks like i need to further lower KFZWOP.
Im going to lower KFZWOP to -values as suggested and see if this helps.

Ok! Log seems good! CWSAWE and KFZWOP should be ok! Your problem is zwspae. I'm wondering if your adress of KFZWMN is correct?

If following statements are true, then ~zwspae (there are some small values added... but not really much) comes out of KFZWMN:
- B_kh = 0 (no warming up of catalytic converter)
- B_st = 0 (no starting phase of engine)
- B_zwmns = 0 (no engine protection)
- B_sa = 0 (no fuel cut)

You could also log additionally zwmnms (ignition angle when engine protection is active), but according to the FR your engine protection is not active when B_sa = 0...

So for me the only reason is still the wrong adress of KFZWMN...
edit: you didn't log this with a cold engine? and I can't open your log... seems to be corrupted...

Engine was well up to temp. I don't know if this has an effect on this at all but I've got CWKONABG set to 0 as I've no cat fitted?
won't be able to check location of KFZWMN until later, but values in the table look acceptable.
