Thanks... Canada is not on their list unfortunately

Hi all,

What is the most recent update on unlocking/flashing via OBD? I currently have an M2 and contemplating upgrading to an M2C and as silly as this may sound I am reluctant to make the switch unless I know I can easily flash BM3. I understand you can get your DME unlocked via bench method but I much prefer the reassurance of keeping everything at OBD level in the event I need to re-lock the DME etc.

Thanks,

You shall remain reluctant for a quite a fair bit longer. With B58 and S58 ... BM3 probably sees no justification to spend resources on Mar 2019+ S55s

Such a shame : that said, if you go get the DME bench unlocked, is it then possible to lock/unlock via BM3? Or does it remain in an unlocked state going forward? Only possibly to lock back via bench? Or irreversible?

Correct. If you get the DME bench unlocked then you can flash BM3 as you normally would. If you have a shop in your area that can do the bench unlock, it only takes about an hour of labor.

disagree. the s55 install base is massive. not many s58s out there yet. and even fewer ready to void it's warranty.

they've said repeatedly that they are working on it. I see no reason to doubt that statement.

also, it's not just 2019+ s55s, it's any s55 that gets an update, which could be anyone going in for service.

To be absolutely clear, that includes 'locking' the DME. So in theory, service dealers have no easy way of seeing that the car is flashed/has been. No error codes relating to DME modification?

I diagree. So many s55 out there and out of warranty. Lots of owners want to flash their used purchased M2,3,4 with s55 engine.

As vehicles get more and more expensive not many owners want to flash their brand new M3 with s58 engine and void their warranty on a 100k USD vehicle.

There is still a huge justification to unlock S55 engine in the M2. The demographic and pricepoint of the M2 makes it a very suitiable car to tune.

The only local shop in Dallas wants 250 bucks and have the car all day to do a bench unlock.

That's crazy because my local shop only took an hour. I was there the whole time and watch them do it

[kyoshi]

I remember posting on here a while back regarding my late 2018 M2C having the crappy 2019 update and when attempting the flash using BM3 it dying on its arse.

I see still no progress other than a bench unlock.. Ultimately during Covid-19 some scumbags stole the car, so up to them now if they wanna crack on lol.

Will hopefully have more joy with my M4

For those interested, checked with protuningfreaks and they came back with:

Once the bench unlock is complete you cannot lock and unlock. We used to have that ability but people ended up locking themselves out so we ended up removing that feature.

Yep that's why i'm just holding off, not too excited about tuning this car anymore.

What shop was this? Cedar? Surprised Matt is quoting that high.

Any update on obd tuning with out doing the bench unlock?

Never going to happen. It would've already happened I doubt they are even working on it.

I found out about this the day I was scheduled to get the DME unlocked but I went ahead with it anyway. Unless you have a major issue, this shouldn't be a problem at the dealerships. (that's just my opinion obviously ).

That said, they later came back to say that you CAN lock the DME again via BM3 but if you need to unlock it again you need to revisit a garage... true? They seem a little confused on their own capabilities...

From what I've gathered, you can lock the DME but it's more or less like a 'soft' lock - Or as PTF put it "different kind of lock that we can apply via app, whish is used for license tranfer and dealer visit purposes. It won't lock the DME completely".

When you get the bench unlock, they basically change the software version to the one which you can lock/unlock just like the pre-March 2019 DME software. However, If you visit the dealer and they update and/or lock the DME, you'll need to get it bench unlocked again as they'll update the software version to the one that's not unlockable via OBD.

That's what I was able to figure out after multiple emails with PTF.

Ok, so the only way to get it "fully locked" (if I were paranoid about a dealer visit) would be to visit a garage who does bench unlocks and ask them to manually lock it again?

What a nuisance... still holding out hope that PTF will find a way to unlock over OBD but I'm starting to give up. Not sure what to do at this point as I don't feel comfortable making any "hardware" changes to the DME while under warranty.

Dude you don’t make any “hardware” changes to the DME to unlock it. Its just programming with a tool that connects where the OEM connectors connect that’s all.

I get that, hence the apostrophe of 'hardware'. I simply mean that my comfort levels differ from:

a. Plug in a OBD cable and essentially transfer software code to the DME plus it's easy to lock again with a similar flash. Vs...
b. Dismantle a section of the car to access the DME whereby the only way to hide what you've done and avoid questions is flashing to stock and locking your DME back to the point it requires dismantling again.
