Can that data be pulled up? Yes but not by a dealership, you'd have to have an insane claim or be acting pretty shady for any of that to be looked into. There are certainly cases where you will be automatically flagged from flash tunes when data is transmitted via ISTA to BMW but realistically if you're just using a piggy back and you pull it off before going in it's not likely you'll have any issues. Now that's not a guarantee, so don't come at me if you get a claim denied it's all at your own risk. But these crazy ideas that a tech is gonna waste his flat rate time to deny your claim is pretty wild.

This. I've only ever done piggybacks, but never removed them for dealer work, except when I spun my hub in the F80. It went right to my shop, and I bypassed the dealer all together in that case. Otherwise, they've never even batted an eyelash. For most work, the logs won't be an issue. For an engine rebuild/blown motor/bent rod, that claim is likely going to BMW first, and then logs will be pulled. Otherwise, I wouldn't sweat it.

I still remember picking up my F31 years ago, and my *salesperson* asked when I was going to slap on a tune and lower it

Even though out of the box these are still fantastic motors, it's a limited version of what you should be experiencing for the cost.

But manufactures have emission regulations that need to be met for the car to be approved for individual countries. Not to mention fuel consumption, if every car was running at their highest output we would have to wear masks for more then one reason. Regulatory has a lot to do with what is allowable in a final product.

It's only 500 HP. Who can live with that😳🤣

So by these flash, how many hp will be added to the v8 engines?
I have x7 m50i
Will it get to 612 of alpina?

This is not true we have plenty of ways to see overboost. Just because it doesn’t store a fault in the main memory doesn’t mean it isn’t stored into another area of the DME that only we can see.

I think you're missing the point here, in order for the DME to record boost in excess of limits, it has to know that boost exceeded the limit. Piggybacks operate in a way in which the DME is tricked into believing less boost is being produced than it actually is.

That said, even with a piggyback, there are various other ways to conclude that a device was used to produce more power.

There are ways in the software (manipulation of characteristic curves, etc,) to make the car produce more boost without the ECU being fully aware, and this wouldn't show up on max pressure logs either.

Regardless, at this point, BMW is obviously paying close attention, and everyone that modifies their car to output more should expect closer inspection should a claim arise that is potentially the result of demanding more than the manufacturer specification - regardless of the method used.

Every thread seems to turn into a warranty discussion. Kudos to Femto for providing a solution for flashing. Now it really comes down to ease of use as sending your ECU for a one time flash is not a practical solution, but still worth it for the minority that are willing to "pay to play".

I've turned two tuned (F80 and a 335xi) into the dealer off lease, the dealer CPO's both of them and sold them WITH the tune still on it. I am fully aware that BMW can detect any tune you put on it, but the CPO process is a bunch of BS and the dealer does nothing, they just mark the car up slap a CPO on it and sell it.

Mostly marketing. They literally put the same motor in different trims of the same car and it makes different amounts of power. It's relative to their competition from other OEMs as well as preventing competition in their own lineup. You can rest assured that when the new M2 is revealed, its S58 will be turned down even more than a base G8X.

Just to add a viewpoint from the other end of the fence, multiple people have bought CPO cars and had warranties denied because they didn't know the car was tuned when they bought it. So it can pretty pretty crappy for the next guy.

This is what I find so odd. I don't think it is particularly unclear: trying to obtain warranty for motor-related damages on your tuned motor is highly unethical. That said I do think this is a minority of customers that tend to post more often in this threads. The rest of us are prepared to accept risk/liability--pay to play!

Don't have a G8x but will be watching eagerly as I fully expect the S58 hp numbers to surprise everyone.

Apologies if this has been addressed earlier, but does the Fontoevo's solution potentially apply to MEVD17.2.G?

You can tune your 50i to over 600hp very easily but you won't have the oil cooling, turbos, intercooler capacity, etc. to safely run at 600hp, like the Alpina and the real M engines do

Overboost can be caused by more than just a tune. Which you should know. Also, as a tech there is nothing that "only you can see" anyone can purchase ISTA and a subscription. The only people who can see anything more than us as techs are the engineers back at base. Secondly with a piggy back the Map sensor won't relay the actual boost to the DME in the first place. Really though, as many have said tune at your own risk. But scare tactics like this are pointless

I would be surprised if your lease cars still had a tune. All software would be updated and settings wiped from the prior owner. :

Never said that. I said pay to play. As in you won't find me frantically looking for ways to hide modifications so I can obtain warranty for the components I just blew on my tuned BMW. It's this unethical and shady behaviour I find odd.

Pro Tuning Freaks can't be far off now as well!

Fair enough but many people continue to waste their and our time by posting all the things they won't do in threads like this as if anyone really cares. Gets tiresome. The forum is for discussion about things that those who want to modify can do.

I pinged them since I had BM3 before. They didnt indicate something was coming any time soon.

Any idea as to whether this unlocking ability extends the newer F87 DMEs as well? My '21 M2C is as-yet untunable!

There is another solution for 2021 M2c, few of them are already tuned

Thank for this. I'm a tech too, sometimes when I read these conspiracies I just laugh. It really hard to get a car flagged. I get tuned m3/m4 or any bmw really weekly. The computer only says that the car may have a tune but it's not like it's automatically flagged. Bmw really needs to sit down a look at those thing if they wanted too. I'm not saying go and tune you're car, things can happen and bmw will find out if they really want to. I had all my cars tuned my F80/F87 and now my G80 with no problems…
