SMG Softare Update

[select]

I am still on the very first SMG Software from 2003 but i would like to try out the newer versions.
I already have the latest daten files but i would like to be able to revert back to my old software incase i don't like it.
I know its "just" a matter of finding the old daten files. I might have found the right one but its a complete version weighing in at 8GB which are split in several 700mb parts on a shitty hoster. :bigcry:

I am pretty new to this, so i am asking if theres a different way?
I.e. Export my old SMG software? Or perhaps someone can send me the old daten files? The one i need is 2882611.

Can anyone tell me what the latest version or id is for the ECU software update?

Mine is in at the local dealers & here's the response I got when I asked them to check out updating to the latest ECU & SMG software:

"There is no software update for your car or gearbox. I've been told E46s don't run software."

:banghead:

Replied to you via PM but here's the run down.

There's basically two software version for the CSL - the 0301 version which came on all the cars and the update in early 2008?? with the 0401 version.

There are then sub-variants of each which breaks down roughly as follows:

- National Japan version (for their fuel) - option code L807A
- EOBD version
- Data record without EOBD version - option code S861A
- V-max unlimited versions - option code S231A

Each one carries with it its own ZB (part) number which is matched to the hardware variant for the DME.

Here's a screenshot of all the CSL ZB versions on BMW's WINKFP



And here's the screenshot of the BMW parts number system showing which is which (well .. 3 of them at least) - the main ones



Basically here's what's what - ZB numbers (bracket is software number):

Japan version
- 7837338 (7837339) - v-max unregulated
- 7837336 (7837337) - standard Jap version software

EOBD Variants
- 7837328 (7837329) - standard EOBD version
- 7837330 (7837331) - EOBD v-max unregulated

Data Record without EOBD variants
- 7837332 (7837333) - standard non EOBD version
- 7837334 (7837335) - v-max unregulated

Each of those above are for software 0401.

I haven't bothered looking into 0301 version, but can most definitely do if requested.

Thanks. Excuse my ignorance, but what would be the advantages/disadvantages of the latest ECU update?

From what I've read on here, the latest SMG update makes the changes a little slower/smoother & as I don't track my CSL (heresy I know), can't see why I wouldn't want this update.

TBH, not sure what the most recent ECU update offers. Someone else here might know?

Haven't driven the CSL much since, but SMG is definitely smoother. Downshifts seem more on the money. Is also better in traffic...less jerky.

Yes mate, if you ask them they will put the latest version on. Don't think they do it as matter of course. They charged me 1hrs labour on my last M3, but didn't charge for the CSL when in for a recent Insp II.

Also, just be clear on weather you want the ECU software updated or not. They may do both together. In my case, I didn't want this.

So will dealers do the latest SMG update if you ask them to (& only if you ask them to?) & do they charge for this service (e.g. if the car ais alreDy in for some other work)?

There are two HW versions listed in the daten files for which there are no 0PAs included -- 7834326A and 7834530A... does the part number you have seem close to either? Could possibly be hidden away in some really old DIS versions. We do have prototype MSS52 software afterall

FWIW - the one dump I have from a real CSL (no idea whose it is) only has 1 flash recorded

All the DMEs have 1 flash ... One of the prototype CSLs ended up in New Zealand as it was destined to be a BMW Driver Training ride car before it was crashed - that car had the prototype tune - I honestly can't recall the HW number now - I'll see if I can somehow get the guy to supply it again - as that motor and DME is now in a racecar.

That dump is probably from my car?? Is it software 0401 or 0301?

I am still searching for that very first software version that all our cars came with but was over-written by the factory when the cars were delivered - it has a part number that isn't shown on any BMW's system, so I presume it was a prototype software.

dame, now I'm up in arms which to get or not. :birdman::finga::hahaha:

Can any BMW specialist do this as I don't want to take it back to BMW here. What equipment do they need for me to check the current update and to reflash to any of the 5 versions. :beer:

Much harder than reflashing my GTR with the idiot proof COBBS. :hahaha:

Glad we are all cleared up guys everyone has an opinion on which version they prefer
Because nz-m3 has tried all the updates he probably has the best idea on which he believes is best but we all drive different and have different preferences

Thank you nz-m3 dude you have been there done that and i respect your opinion

All of our cars came out from the factory with 2 flashes of the software ... an original and a delivery software ... then there was a BMW actioned update, so most of these modules should have at least 3 flashes taken up already.

My post was originally to make sure that you weren't getting duped by companies that offer these upgrades - not intended to offend! Apologies if it came across that way.

As for software versions and what they do - my feel (and having tested a few of them out in my own car over a period of time) is that with each version it has gotten softer and smoother but also with less clutch slurring.

I still currently have the latest software in the car in the spare SMG module and I must say I have grown to like this version a lot more now as it certainly seems to provide much more mechanical sympathy to the components during shifts of varying speeds and throttle application.

My thoughts - most likely a worthy update if you want longevity and less clutch slurring, but maybe not so if you long for that bang away super fast gear changes and feel like you are a F1 super star.

The later software slows the change down and smooths it out, I think I ran the original version when I raced with SMG, I certainly flashed it backwards to make the shift more aggressive.

I'd go with NZ if he states revision 3 was the peak.

ETA Motorsport near Brands Hatch have Autologic so if you need anyone in the South East ?

Ok an update.i ve spoken with the company that installed my update and i misunderstood what i was told so here goes:ive had 9 updates of a maximum of 14 before the ecu needs replacing.the 9 updates are not 9 different updates but possibly the same updates done once or twice before hence i understood i had 9 updates so apologies for misleading anyone i genuinely misunderstood what i was told.

So as the tech and nzm3 say there are indeed 5 updates for the csl

Hope that clears it up for everyone

Also autologic have quoted me £10k for their software so im gonna redirect people wanting updates to bartletts.damien offers super service and great prices

Thanks
