For the E46 non-Ms, autos and manuals use the same software number

I bought an extra MS43 dme to use it for testing but my pa soft 1.4 can't sync the EWS coding so I gave up on this. I hate EWS3 if you have info on how to eliminate it I would like to know

Have you tried using DIS or INPA to align the EWS with the DME?

Driving a 330XI Automatic Car, European EU4, with tuned Software. Flashed with CarTune and modified by four Tuners. Tested all of them, but getting worse with the EU4 Regulation. My Idea is now to flash the EU2 Software.

I've done several EGS-Updates with WinKFP - but i don't know how to flash the EU2 Software ...

Same process - just manually input the ZB number.

Officially no EU2 software exists for the 330xi, but the RWD software would probably work fine (I'm not making any guarantees though).

Try 7545671

Amazing, i've flashed the software and is the same one which is programmed on my friends 330i with a Special Package, called "SA Leistungsgeprüft/Pressefahrzeug". It means, that BMW has tested this car on the Dyno before it goes to the magazins to test - its amazing, that this software does so more torque than the EU4 Software!

AND:

In cold start and warm up, my engine gets a little bit terrible, becouse you feel a little vibration at your ass, 30 seconds after cold start - for 10 seconds - after that the engine runs fine - BUT with EU2 Software, it solved the problem


But now: is there a way to retune the software for a little bit more aggressiv vanos or throttle? i've checked out, that my automatic gearbox will not shift automaticly up in manual mode, the engine runs into the rev-limiter. my old version has a tuned rpm-limiter... :-/

The same people who modified your old one should be able to modify this. It's not really difficult to raise the rev limit, but I don't know how to flash modified tunes with winkfp. Pretty cool that it made such a difference though!

You're the one who used a ZHP EGS to raise your shift points right? It might be worth flashing a non-ZHP EGS software until you can get your rev limiter raised again

Back searching, is there a Software for SA199A (Without Catalysators) ? I've read out my Memory and it says "Lambdasondenheizung Bank1 und Bank2" - becouse i've removed the post-cat-Oxygen sensors. Engine runs fine and smooth, no MIL or something, only this two failurecodes

What is the version number of your dme software with "SA Leistungsgeprüft/Pressefahrzeug" ?

EU2 and "without catalysator" are one in the same.

Were the lambdas plugged in when you flashed the tune? If so, try reflashing with them unplugged. It seems the DME decides what configuration to follow based on what connections are present during programming. Same reason why you have to reflash the DME for an auto->manual conversion even though the SW is the same.

Does anyone know where I can get the V41, V42, or V43 Daten files for an E46 M3?

=Nevermind, I found it.

Terra, Hakken,

Where are we on this? I think we're fairly close to cracking this. What do we need at this point?

Has anyone made any progress with this. I feel like if we just had tuned versions of ms42 and ms43 software they could be inserted into the
factory software.

Does anyone have any tuned ms42 files (M52tub28). If so, I could attempt to amalgamate them with the euro 2 tune. If that works on my car, I could toy with doing the same for ms43.

My Ride: '04 330Ci
I really don't want to see this effort die as the lack of viable tuning options has been the reason I've been hesitent to get another E46.
With that said I'd like to put in my thoughts to hopefully help this along.
I tuned late model domestics (mostly newer Chrysler stuff) professionally for a few years using primarily the Diablosport Pedator and CMR software.
The basics of it were that you would save the original file as a back-up before flashing anything (something they designated as a .ori). These files were pretty large (150-200kb iirc). These files included things that were background data that never showed up as adjustable parameters in the software.The Tune file that was flashed was basically only the parameters that were adjusted and ranged from 20 to 64kb. I'll have to check the file sizes later. But the point is that I don't see how the entire map can be stored in the few lines of code you guys are pulling (or posting at least). It seems like it should be 10x or even 100x as long.
Now I haven't gotten Tuner Pro yet to check things out but from a tuning stand point I (we) would need more than just rev limiter adjustments.
Off the top of my head:
Injector tables (scaling, cold start, hot start, battery offsets, etc...)
MAF/ VE tables
open loop and closed loop fueling tables
Spark tables
Knock sensor tables
Hardware switches (turn O2's off etc)
Fan control
IAT related tables
DBW throttle control tables (and ALL associated tables: on many boosted Chryslers you have to tune out a "hanging" throttle condition at high RPMs through expected/calculated airflow tables)
Idle speed control
and I'm sure many more...

I hope this helps to show you what we need from the end result of the effort.
Thanks though for what you guys are doing.... keep it up!

I am able to tune my MS43 using WinOls software, and WinKfp software for flashing the tune into my E46. But my 2002 330ci is bone stock and I like it that way so I am not much into tuning it. In fact I will wait until the registration expires on it and just sell it, I am tired of E46

You've succeeded in using winkfp to flash a custom tune? What'd you do, convert the binary to intel hex and tell winkfp to ignore checksums? Or do you know how to calculate the checksums?
