Hi

I have searched and searched but cant find too much info on this, could someone give me a quick breakdown on what maps need to be changed for a stage1 tune?

Thanks

Hi,

usually include the following..

Lambdakennfeld bei Teillast
Berechnung aus Drosselklappenwinkel, Nockenwelle spät
Drehzahlbegrenzer
LDR-Sollwertbegrenzung
Kennfeld LDR-Sollwert
Zündwinkelkennfeld
Lastschwelle für Turbo-Überladeabschneiden
Kennfeld Höhenkorrektur für LDR-Sollwert
Luftmassendurchsatz ML-Schwelle für B_maxflr-Diagnose HFM/HLM
TV - Kennfeld für LDR

Thank you

What do each of the maps do?  such as load maps and lambda.

I know what are the timing and lambda maps, fairly sure which ones are load.

Is there no hard rev limiter in the M3.8.3 ?

While driving it feels like running into a wall, its no typical bambambam sound.

DTC: 00543 035 Drehzahl nach Maximum überschritten

Far as I can tell it's calculated. What flash number?

flash number?

06A906018AQ - D03 - 0261204678 - 1037358108 - 0x3939.Ori

It will be easy to understand if you compare them with maps playing simiral role in well documented ME 7.5. I think they can be compared as follows (ME7.5 vs ME3.8.x/ME5.9.x):
LAMFA (+ KFLBTS & KFDLBTS & KFFDLBTS + KFLAMKR & KFLAMKRL + ?KFLF) = (KFLF) Lambdakennfeld bei Teillast
NMAX = (NMAX) Drehzahlbegrenzung
LDRXN = (LDSMXN) LDR-Sollwertbegrenzung
?KFMIRL = (KFLDS) Kennfeld LDR-Sollwert
?KFMIOP = (KFTLWS) Kennfeld für tL - Berechnung aus Drosselklappenwinkel, Nockenwelle spät
KFZW = (KFZW) Zündwinkelkennfeld
?KFDLULS = (KFLUL) - Lastschwelle für Turbo-Überladeabschneiden
?KFLDHBN = (KFLDSHK) Kennfeld Höhenkorrektur für LDR-Sollwert
KFMLDMX = (KFMLDMX) Luftmassendurchsatz ML-Schwelle für B_maxflr-Diagnose HFM/HLM
KFLDRL = (KFLDTV) TV - Kennfeld für LDR

This was very helpful. Thank you. Anyone have any pre-me7 reading recomendations? I'm interested in m3.83/5.92, but anything I need to read prior to getting into that is welcome.

Anyone have a good understandig of the fuel calculation?

From MAF sensor > Injector PW

I defined, translated, and categorized the SHIT out of the 557P file. Fueling is still a bit hazy though.

Anyone have success disabling the Rear O2?

S4 wiki has:

CDKAT - Cat diagnosis in OBDII-Mode.
CWDLSAHK (0x18663) - Code word for probe aging after KAT[39]

but my 558M definition has neither.

Maybe anyone share some info about how it works in 3.8.3 ?
Readed many info about ME7.5, but it not looks very similar to M3.8.3 to me.
Maybe some basic how it works in 3.8.3
- fuel
- boost

Thanks in advance

Very resumed:

1 - Load [ms/umdr] is opening time to obtain lambda =1

2 - Load = torque x factor

3 - ECU just request load (that is torque, that is translated to MAF reading through Grundanpassung KHFM) and pulse N75 accordly to reach the requested load

4- Fuel is only based on MAF reading with temperature and TPS corrections

Here is some info that I have collected. I think that I have more at home. I hope it will be useful.
Regards,

this is so useful!! thank you!

In the 06A906018CG_352127 ECU I cannot find the parameter/s for NMAX
I have found NMAXDV (0693A), NMAXF (069EC).


Can anyone help?

good topic,i also h have interest to know what maps need to change to make my injectors open more and inject more fuel in this m3.8.3 ecu?

Also is it possible to raise RPM limiter?where is the RPM limiter?

RPM limiter is here ;

Can someone please explain why my old N75 valve behaves like this? (left column)
I tested the Valve, resistance was okay, it clicked when tested with vcds and i did all the other stuff described here
http://www.tt-eifel.de/index.php?n75

So whats the difference between old and new N75?

Include TB angle, and turbo hardware/ mapping version.
If the conditions for both pulls are the same -gear and TB angle and mapping, then one on the left is working (the one you labeled defective) and the one on the right would appear to be in response to less load being calculated. Ie the ecu calling for extra load by ramping up "output" n75 duty cycle. this one may not be working or you have another issue.

Edit: im not 100% sure if this was the same gear like before. I will create some new 4th gear pulls soon.

Where on earth do I find the acronym list ??  How does Drehzahlbegrenzunget abbreviated to NMAX?

I have trawled ecuconnections and I have obviously missed  the list of map abbreviations.

I have the damos abbreviation pdf and it doesn't list any of these. Please assist if possible,

Any help?

Ever heard of Alpha/N? N is pretty much a universally accepted abbreviation for engine speed, if you don't know that, then you need to check some basic things again.
As for the other abbreviations/acronyms, they've all been posted here and elsewhere.  Some of the similarities above are wrong too.

Thanks for the explanation of NMAX. So... NMAX is the Maximum engine speed (RPM).  As discussed earlier in this thread, the m3.8.3 does not have a NMAX value and the RPM limiter is calculated.

From a bit of self discovery, I have enabled the ID column in Winols which shows me all the abbreviations in the M3.8.2 Definition file. I finally know what you guys are referring too when you start rattling out abbreviated terminology. Slow and steady..

I am currently comparing m3.8.3 manual translation projects created by pvl (06A906018R) and automan01 (06A906018CG).

But even for the first map '(KFLF) Lambdakennfeld bei Teillast', the offsets are different between the 2 projects.  Then I search the offsets for KFLF in my 06A906018CH ori file, and the offsets are different again.

Is this quite common that different ecus in the same m3.8.3 family have differing offsets? Or should they be identical?



  

Welcome to the Bosch world! you should see on newer cars, where the maps still exist but are different sizes from a sw version to another.

where can i find these definitions. im just getting started with m5.9x and want to figire out a few things as there almost no documentation outhere

this is gold <3
