Compatible BMW ECUs for Cloning

I thought Bosch had started to lock all ECUs for BMW?

There’s a bold statement up there. Dates still apply.

I'll blame T.S. Elliot for that.

So for 'compatible' ECUs for cloning, is there anything on the ECU label (other than the date code) that would indicate the correct model of ECU from an unknown BMW? (I know this is a Supra ECU pic from an earlier forum post). Is the 1039T28833 what we are looking for or something else?

No, the 0261s100as number would be the one to match. Using any of the other numbers could result in getting an incompatible ECU.

Just so everyone's aware Femto can check the VIN to see if it's compatible, but they don't have comprehensive list of 0261 ECUs that will work.

According to Femto, only B58C and B58D engines will work.

this is inaccurate

Can you clarify how to tell if a scrap ECU would work by what's on the label? Once I have a compatible ECU from early 2020, can you provide the service of getting it cloned from a post 06/2020 ECU?

How so? Search for the 0261xx numbers and you'll see they match other compatible ECUs. The 1039t28833 will not get you the same results.

I should also add that you obviously need the correct date as well.

I know that 0261s100as and 0261s1012a ECUs work if the date is correct.

But did anyone find a source? PM if you’ve got one to sell… ?

What if I have a cloneable ECU but no VIN to the ECU?

 

[zrk]

You don’t need the VIN, it’s used to verify compatibility

@zrk need you expert help with compatibility.
A buddy of mine had this extra ECU (unsure what vehicle it came off of) and donated it to me. Are you able to determine compatibility by the ECU label?
1st picture is the donation ECU.

Can't tell by the label unfortunately, but that date is too late anyway.
