ECU/DME Check for Cloning

[zrk]

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.

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!

Thanks for the great advice, this will definitely help me find the ecu easier.

Not true actually, 540i (G30/G31) and 640i (G32) have had B58B30M1 engines.

I see quite a few m240i 18-20 ecu's on ebay but zrk mentioned its been raising complaints.

Found this another ecu wanted to know if this was cloneable.

I looked through all the info in this thread and the other one that is referenced. I don't know how it was originally compiled. This is a listed (from this thread) compatible ECU, the date is 5-28-20. Does the 4 days from 6/1 actually ensure this is cloneable? Thanks

 

[zrk]

Yes, that should be fine.
