Really? That's odd.

both 2020 & 2021 use the Bosch MG1CS201 DME with the Tricore Aurix processor. I own a 2021 M340i and there's a 2020 M340i at work.

For the bootmode read/write exploit, this was patched by Bosch in ~August 2020. This was a global update for all of their ECUs, for all manufacturers (VAG, Mercedes, BMW, etc). This even effects new MEVD17 ECUs (previous gen Bosch ECU) like what's in the F87 M2. This was presumably to keep their customer's happy since they likely got the contract with various OEMs partially due to their updated/upgraded security features implemented in the MG1 family of ECUs.

If you or anybody has any questions about any of this feel free to ask.
Theoretically, wouldn't it be possible to put a 2019/20 ECU into a 2021 model since that could be at least bench unlocked then? I just bought a cat less DP and now I'm debating on returning it if it's going to take (estimated) a year to break this lock

No, because the 2021 have the mild hybrid system.

I don't see how that's an issue. The ecu can be cloned to a new one. If it's the same hardware, the only difference is the programming on it which can be adjusted by the tuners. At least that my hypothesis so don't quote me

Thats actually promising if Q1 2021 is accurate. I was thinking it was going to take a year or close to it as mentioned in this thread.

I'd be okay with having a flash by spring/summer this year coming.

Where did you hear that if you dont mind me asking?

Reaching out to different tuners. I wont say who specifically mentioned Q1 and I wouldnt say my word is matter of fact either.

I believe it when I see it and remain hopeful and thankful until then.

The other day I asked a local tuner here in NJ and the guy pretty much told me it can either be tomorrow or 6 months from now.

JB4 is really easy to install. The basic setup is 3 connections, TMAP, MAP and CANbus (the real difference maker tuning wise!).
Dave?


Thinking about just going this route for the time being.

I've read mixed reviews on the JB4 for the MY21 such as it only improves dyno numbers and launch but 1/4 is same or worse than stock.

Any feedback regarding those statements? I'm a pretty avid 1/4 mile'r myself and rarely, if every go out to the tracks like Thunderhill

I haven't seen any MY21 times posted or at least anyone saying they were from MY21 but don't see why you'd have any problems. Unlike the other systems JB4 has EWG control.

Throw it on and do some measurements. If you're not happy with it return it or sell it.

I was told that these same tuners are trying to work around it, but not to expect anything for a little while, as its going to take time IF its able to be done at all.

I was hoping to flash my car soon. Oh well. I have to wait now.

Anyone else hear anything about this? Any vendors with anymore info they can provide please?
Talked to the folks at protunning freaks (BM3) and they are saying the same thing... its really bad for customers to spend $600+ on a flash tune that is unusable. Even if you bench unlock the DME, there is a chance BMW will update your car and relock it.. very frustrating. Protunning freaks said they can bench unlock my DME for free.. just have to pay $120 total for shipping....

The 2021 model year DME cannot even be unlocked to be tuned at this time. They are working on a solution now... its only a matter of time until someone cracks the 2021 DME. Once they do we will all be a little bit happier I think. I personally cannot wait to have my car flashed to stage 2.

I don't recall where I've seen it here, but I've seen posts in a few places online - https://www.n54tech.com/forums/showthread.php?t=63688.

What you'll generally find is pre-DME lock people were recommending a flash tunes over boost controllers, etc. However, all I've seen of late are those same people that have unlocked DME's with a flash tune continue to recommend that over JB4 and others - not aware of or being ignorant of the fact that newer BMW's (and Supra's for that matter) have no option of flash tunes right now.

That said, I just purchased JB+ (because I'm in the same boat, locked DME), will try that out and if that seems promising, which I suspect it will be, I will likely upgrade to JB4.

I have seen nothing but good results for JB4 and other modifiers. I think there's certainly a YMWV aspect to it depending on what boost setting you're on, your fuel being used, etc. on the types of results you get. For the money - you can't go wrong trying JB+/JB4 and just return it if it doesn't meet your expectations.

I had a JB4 on my E90 and it was okay, definitely better than stock but it was too "safe" for me if that makes sense? LOTS of CEL because I only have access to 91ACN and didnt realize at the time how close I was to E85.

With that said, I'd definitely be willing to go the JB4 route, not against it, just dont want to put out $700+ for the JB4, EWG, and monitoring app just to spin the tires and not see any real results at Sonoma Raceway.

Would love to see how the JB+ goes.

I'm definitely getting the itch to go faster with the lack of rain and Sonoma's 2021 season around the corner.

I have a jb plus set to max boost, and I can confidently say it's not that noticeable compared to stock... I also ran a BM3 stage 2 with a downpipe and that was so good especially now the summer time.

I think with JB, less could be more in terms of adding boost. From the feedback I've read, people have better luck and response overall from the car when it's not turned all the way up. I'll be trying it out over the next few weeks at various settings to see. Of note - mine showed up today and was set past the 3 o'clock position (it's supposed to come pre-set at 3o'clock - it was set closer to 4-5 o'clock). I set it just past 3-3.5 position.

On first drive, throttle felt slower/sluggish at low speeds, 5-30mph. After a few miles it picked up a bit in response. Going to take it for a spin tomorrow again, then turn it down to 2.5-3 o'clock position. Then all the way up to 6 o'clock.

Yes that could possibly be true! I have had a JB+ for a year now and have tried various boost numbers. Don't get me wrong there is a difference but for $200 USD I think I should have just gone with BM3 from the start. That being said for the ease of install, removal and slight increase in performance I'd say a JB+ isn't the worst option out there.

Are you a B48 or B58? The B48 makes tiny power stock and while it makes more tuned it's not like huge gains or anything. JB4 adds like 30whp on map2. JB+ I bet is a little lower.

B58 is an entirely different animal.

Unfortunately a B48, with a downpipe. I know the B58 is an absolute monster. That's why I ran a Bootmod3 Stage 2 in the summer and I live in Canada so for the winter I was running a JB+ no stage 2.
