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.

I believe this is false information. it has been said multiple times that an older version isn't installed. it remains the current version.

Yep, I asked him why it wasn't $150 and he said because they have to do 'physical labor' to get to the ECU to bench unlock it so it's $250 instead of $150 if you bring in your ECU.

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.

I hope you are right of course :-)
Only one way to find out ... 16 months and counting ...

[prompt]

If you bench unlock the ECU,flash a new map using BM3 and then you need to go back to stock for a dealer visit,is it easy for the dealer spot that the ECU has been unlocked?

Then go back to modified require a new unlock?

Sorry if this has been asked and/or answered already

Unfortunately yes. DME unlock will flag a standard DME tamper code so as soon as they plug in a laptop it'll be front and centre. If you lock the DME with BM3 you need to go back to a garage to have it bench unlocked again.

Feel free to correct me someone! I'd like to be wrong...

Thanks for the answer,
even if you lock it again the tamper code will be visible?

There is a topic in the F80M3 section, where a BMW tech recently discovered that bootmod3 ecu flashes will be detected even after flashing back to stock + locking the ecu.

Worth a read through before you go the route of bench unlocking, bootmodding, and believing you can still claim warranty after something goes pear shape.

I think my concern isn't so much claiming on engine warranty after I've tuned my engine, because... on my head be it if things go wrong. What I am concerned about is say, a warranty claim on something unrelated to the tune but a tech discovering the car is flashed and immediately defaulting to "sorry, warranty void". I'd like an easy way to 'hide' the flash at a basic level so a tech doesn't use it as a cop-out.

[m20e3087]

How to handle the SA when it comes to changing out plugs? I am running NGKs, early next year will be my 30K service.

What should I do??

Buy pair of OE plugs and put it back in?

Or tell the service dept it's already been done and decline the plug service?

Or hand them my old plugs and say if BMW asks here they are and give me 6 new plugs.

That would make sense, but an aftermarket exhaust + an annoying tech would possibly give you the same result.

Quick question...

Does bootmod have an option for stock tunes? Like, going from M2C to a M4 comp or GTS tune for example. Is that possible? Or does it only start at stage 1?

[doughboy]

Yes there a several stage 0.5 options as i call them

[ssabripo]

has anyone gotten "GTS Roar" feature to work?

Does anyone have a clip or description on what it's "supposed" to sound like? I have it enabled and don't think it's operational on my car. I had PTF guys remote log in and help, and they basically changed the burbles in custom mode (increased them) and that was that, but I thought it was supposed to be a Startup/Cold Start feature...

Am I confused here?

No you're right, should rev the engine higher than normal on startup. That said, only works if the engine is warm.

Do you have something similar to this in the UK?

I think / thought that BMW only does that for items you've changed. For example, if you change out your suspension then your suspension warranty is void. So in this case an engine tune grenades your engine, they won't cover a replacement engine.

Say you go in because your tail light goes out, they won't deny just because it says your DME is unlocked or that your car is tuned.

But if you go in because your cats fail, they might deny the claim if the cat failure was due to your engine tune (higher EGT or whatever).

Correct, if you put a tune on your car they can't deny your warranty on a tail light, it has nothing to do with it.

Unfortunately I live in the UK so that act doesn't apply to me.

That’s why when I took my car in for service I left the tune on and told my SA to just perform the service and not perform any ecu updates.

Wait... so you're saying it's safer to take your car to the garage WITH the tune loaded than load the stock tune (which will then require another bench unlock?)

That’s why when I took my car in for service I left the tune on and told my SA to just perform the service and not perform any ecu updates. I took a risk when i did that. If I had known earlier about this tamper code issue, I wouldn’t have got the bench unlock.

Edit: I AM NOT RECOMMENDING ANYONE TO DO THIS. It’s just for the sake of other forum members who are on the fence about getting their DME bench unlocked. It’s a risk and if you really want to do so be prepared to cover the repair costs if BMW denies your warranty!

this is the part that's confusing...

Are you saying that once you unlock, and you flash the tune, if they hook up your car it, it will NOT show the tamper code?

I flashed my car back to the stock tune and the dme started throwing the code again. I think it’s related to the BENCH UNLOCK and once you tune the car, the tune hides the code. That’s my GUESS and I hope proTUNING Freaks can shed some light on this. That being said, since the car just went for service and not warranty work I’m sure the dealership didn’t do a deep dive to see whether the car was tuned or not. It just wasn’t throwing any codes with the tune on!

Ok that makes sense. Yeah as far as I understand it BM3 removed the ability to re-lock the DME as it was causing issues. The only way to visit a dealer 'clean' is to flash to stock and then have the DME re-locked manually. Then again, they can always find out if they want to.

[blitzyo]

Sorry if it's been asked but does the cs+ map benefit from going highflow or catless?
I'm guessing the stage 1 does.
