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.

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.

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."

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.

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.

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.
