For sure, the butt dyno alone felt like a night and day difference. The M2C for sure was crippled from the factory.

Okay, I’m totally convinced that the bm3 time would be incredible. Does anybody know of someone in the Chicago area who can do a bench unlock? I’d rather not ship the DME and be without my DD for a week.

Yes, I am in the Chicago area. Let me know if you still need this done. I took it to a shop in the West Suburbs who unlocked it for me. PM me for details.

Unfortunately, I'm a new member and it won't let me accept PMs until I've posted enough replies... not sure of the best way to handle it!

I have an early 2020 M2C. If I hookup BM3, it can connect and read the VIN etc, does that mean it can be flashed or just because it can connect, doesn't mean it will flash?

Just check your istep version. There is a guide on these forums. That's the easiest and most sure fire way to know. Others would just be guessing

Fwiw, my car was delivered June 2019, and mine was locked.

But you can be bench unlocked and he probably can too.

Reach out to BM3. They are quick to respond and very helpful. They can clarify in a few minutes!

Wonder if it's possible to get the 450PS M2 CS Racing map on to bootmod3.
I know there's a street legal car in Germany that's already been tuned. Should be possible to get the map off it.

Would love a linear track OEM map.

sorry to revive an old thread, I have two questions -
I have a 7/2018 build, I should be unlocked right?
Has anyone used a macbook for BM3? I saw they now have support for iOS, does it work just as well as windows?

Hi guys, unlocked our DME on our 2020 M2C today (DME build day was june 19) then flashed with BM3 Stage 1 93 file and GTS DTC tune. Surely made a difference in butt dyno and performance dragy numbers. Was hoping for more performance but can't complain for just a flash. She has 12k miles on her, not sure if I should do plugs soon, itching to do stage 2 with a high flow dp.. Anyway here is a before and after 60-130. Yes its slow

Just sat and read through this whole thread, lots of useful information.

So, as of May 2022 what is the latest with all of this? I'm surprised this thread went quiet with no updates.

Is it still a no go for the OBD Port tuning?

Yeah I've flashed my car using all methods. Works fine. 2018 build is unlocked if you didnt update to new ecu firmware.

Depends on the DME. If it was made after June 2019 maybe. If it was made after September 2019 I think no.

To clarify the unlocked / locked Questions. There are two different types

to 06/2020 - DME can be locked by software, it depends not on the production date due 06/2020 every DME can be locked by iStep from BMW. But this lock can be unlocked via bench

after 06/2020 - there is another Hardware Type installed, this DMEs can not be unlocked as such as easy. Best option is to change the DME to an older version.

We can do both solutions. (EU / USA only via shipping)
