Hi, I found this ecu for sale, and wanted to know if it was cloneable.

How can I tell for sure if it is? I don't want to buy it and ending up as not being compatible with my cars ecu.

Oh no idea. Someone more knowledgeable can chime in.

No dice, it's B58 Gen 1.

Thanks for letting me know.


There's another ecu also wanted to check. Take a look.

No problem. This one's a N63 DME. An easy way to check are the 0261 numbers. Usually you'll find old listings or online tuning files that tells you what engine it goes to. Alternatively the big numbers like "9844147". Both numbers always tell which engine the DME goes to.

Ah ok, thank you, I will continue to look for ecus. Any advice on an easier way to find some?

Found a couple of good DMEs on eBay the past year, and got one of them, not sure if they're there anymore, but looking at scrap part auctions and just searching on eBay for generic terms like "BMW DME", "BMW ECU" or "BMW ECM" maybe adding other modifiers like 2019/2020 etc.

Check for some cars that had a 2019/2018 starting production, like the 40i SUVs, the Z4, m340i, 840i etc. Not to say you shouldn't look at 2020 production cars, but the likelihood of finding one is way lower.

On the first page of the thread there's some of the good numbers for ECUs. You could use those to quickly filter out any ECUs you find.

It takes a lot of time but when you end up finding one, it's definitely worthwhile IMO. I picked up mine for $350. It ended up being cheaper than getting Femto to unlock the DME. Anyway good luck!

If it's 2020+ it's fine.

No, it's not. The 740i did have a Gen 2 B58 revision, which your post mentions. However, the ECU CTNlMF sent is the Gen 1 B58 version, for the 740i. Moreover, it's the same ECU revision used on the 540i and 640i, which only have the Gen 1 B58 had a Gen 1 B58 revision.
