Yeah, I'm ready to proceed as soon as BM3 is.

Reviving this old thread. Any updates on an OBD tune. I had BM3 in my f82 and do not want to mess with JB4.

You can alreqdy flash tune these cars, just need to send your ECU to femto for an unlock or clone. Also, bang for your buck the JB4 is proven to be effective and very safe using lower maps.

It’s not only a unlock …. I am 150% sure they change a chip inside the DME
And after they program it !!

[Celticsfan34life]

In for the day a tune becomes available that doesnt cost 2k on top to unlock the ECU lol

I know you can do this. I want an option like my f82 where I can just flash tune it through the obd. I wonder how long another company can unlock it so we can flash tune.

probably won't be for a while

Trust me when I say this - the moment someone concocts a method to unlock ECU via the OBD2 port, you will know about it. It'll be plastered everywhere and there will be non stop threads about it.

For now, it's in the best interest of the person/people that is/are working on an unlock method to wait. We're currently only 2 model years in, so there wouldn't be much money in it for them. As soon as there's an exploit, BMW will rush to patch it and it'll mean that the cars getting produced after that point won't be able to enjoy the same OBD2 unlock. The demand is not quite vast now, but it will only increase, so we'll just have to sit tight until it's released. I honestly wouldn't be surprised if there's a method already but the masterminds behind it are waiting until there are thousands of more interested owners out there

This is also not to mention that many wouldn't risk their warranties by flash tuning their cars (I wouldn't), thus even further shrinking the number of interested parties. So I'd wager a late 2023 or 2024 release of an OBD2 unlock. But that's me being a bit pessimistic, pragmatic, and thinking like a businessman.

Femto can do this, they are just protecting themselves from someone sniffing through the CanBus, and figuring out what the exploit is. It's protecting their work and it's fair.

Stop it. Tuning your car doesn't void the warranty!! Lol. Just ask any of the vendors who sell them🤪🤥🤥

So, I was just thinking, and maybe oversimplifying what I'm about to suggest but...

Can't someone in the tuning business here in America send a DME to Femto to unlock it, get it back, and reverse-engineer what they did? Even if its a chip they added or code they change, shouldn't a tuner be able to figure out how to duplicate the work?

I'm wondering why only one company in the entire world has the capability to software tune the ECU's?

My guess is that they flash a custom bootloader that can use the previous exploit, the one used by everyone (BM3, MHD, Ecutek, etc) to write the DME binary.

No one knows how to flash that bootloader, because if they knew, we won't need Femto in the first place. When Bootmod3 say that they require Femto unlock, what they really mean is that if the Bootloader is compatible with their tools.

They don't, they just flash a bootloader. Femto has said that they don't do any HW changes to the DME and they are right. One easy way to prove it, is that if the BMW remote update service is enabled, it can wipe it back to factory settings.

Also the Dealership can flash it back to factory, so this is not some physical change, it's a SW change.

Wtf is femto?

A Russian company that figured out how to flash the G80 DME and 2021 Supra DME.

The thing is that, you need to send your DME physically to them, wait a few days and then when it comes back, you can use BM3 or MHD.

Please copy all of your passwords, pin codes and keys from your house and safe, so someone can "figure out" how to get all of your investments. It's so easy to rob someone, especially when you have all of the keys, isn't it?
Think of it as if we are giving opportunity to another companies to truly figure it out by theirselves.

They lie
They change 1 chip inside with the same as oem but virgin !
That why bmw can relock with ota after reprogrammed…

The machine to change the chip is very very complicated! Like steam machine
Very hard to do , that why for now it’s the only one !

Will see in the future if I am correct

I believe I understand your analogy.

However, reading some of the previous posts, I think AhsanU hit the nail in the head. He said (and I'm paraphrasing here), "...there is not enough market for such an early model to invest on R&D to unlock the DME..." And to add to this, most G80/82 owners that want to chip their cars are pretty content with the JB4 and/or the RC from the "return on investment" perspective; $700-$900 compared to ~$4K. (IMO)

Didn't mean to ruffle any feathers for posting a question that is probably in everybody's mind, including potential competitors.
