You can get spare ECU all you want but BMW tracks tunes in multiple locations. if you don't think the iDrive interface tracks boost etc. which can also be used to see if your car has a tune than you will have a suprise when something happens.

a vlogger said mission cracked it. oh it must be true then
mission says they cracked it but won't release it. oh ok.

0 videos of a g8x, new m2c/s, m3/4, or supra cracked.

it's all bullshit until I can actually buy something.
sell me the unlock/tune or STFU. it's all just an attention grab until then.

Maybe you guys forgot the S58 was in the X3/4 M. Don't know how different the ECU is from that platform, but I'm not surprised they got it available for the G8x.

Catless downpipe and BM3 tune, at the time, made the X3M wicked fast.

Just because these tuner shops max out their shop car doesn't mean everyone should be doing the same. If they blow an engine, it's a business expense and they can get it back on the road in a matter of days or weeks.

In addition, that shop car likely made multiples in terms of return on investment for what they paid for the car and the mods they put on it. The clout is meant to get people to buy their products while us mortals have a depreciating asset that we are gambling with.

I don't disagree. What I am saying is if one does not drive around like an idiot and is hyper vigilant with a strong maintenance routine, a modded car with bolt ons and tune doesn't have to be like Russian roulette. I know lots of folks that break stock cars, while I have zero problems because I take care of my cars and I hire tuners that know what they are doing and are transparent about the risk.

It is an age old discussion that always gives me entertainment. Guess that is a personal problem of mine... haha!

A tune running E60-E85 is just what the doctor ordered. It would turn it into a torque monster.

It's not.

My buddy's stage 2 is neck and neck.

The problem isn't with you or a lot of folks on this forum. It's the people who want to buy a brand new G8X, run a max effort e85 tune yet don't know how to read a data log lol

Even if you avoid getting the car plugged in for dealer service, if there is a mechanical issue, they WILL plug your car in and see the DME has been tampered even if you flash back to stock.

Just a warning to those who are itching for more power. I personally think it's too early to tune unless you are willing to pony up for a new engine in the event there is a weakness in the S58 that has yet to be discovered.

I have read on here that dealer can see if car has been driven out of preset parameters, ie boost etc. so they would likely flag the car for a tune even if they could not detect one.

What about 06/2020+ S55

You'll need to bench unlock and load the old boot loader for you to flash via OBD2.

Correct, our cars have a black box (like many newer cars now) which log all parameters for a period of time. This data would be reviewed by BMW NA in the event of a major repair.

Can't bench unlock these DME's yet.

Your not wrong everyone just says stuff just for attention now a days with absolutely no proof I'm with you I'll believe it when I see it. Plus it took a long time for them to crack the F80's it's hard to believe they did it that fast.

[prompt]

this means that locked S55 can be obd flashed soon without bench unlock ?

[SteveChester]

Looking forward to the BM3 maps then

Does the S58 engine suffer the inherent crank hub issue from the S55 engine or has it been redesigned?

So far, so good.

I’m in the somewhat skeptical camp here. It took years for the Bosch ECU’s on the Audi B9 platform to be cracked and while reading up on that topic it seems like there are a handful of folks out there with the tools and skill set to work on cracking the encryption who then farm it out to all of the tuners. That’s why we usually see several tunes out within months of each other once the ECUs are cracked. Maybe Mission is one of that select group, or maybe it’s different now.

Either way the “we cracked it but you can’t have it yet” is a little sketch to me.

While I’m still waiting on my G80, this might be the first car in a long time that I don’t tune. Between the hardcore stance the manufacturers are taking to thwart tuning and the fact that I can’t use anywhere near the stock HP on the street, I don’t really see the point. It’s one of the reasons I opted for the 6MT, I get some involvement in driving at any speed.

I’m all for choices and it’s potentially good news for anyone who really wants to tune and is fine with the potential risks, I just think for the first time in almost 20 years I’m gonna pass on ECU tuning/piggybacks for more power.

ECU for the S55 cost around $1,800 as I had to replace my ECU since it was "bricked" attempting to return to stock prior to service for my SCH. Dealership where I ordered requested the VIN number, as this is tracked by BMW NA, and the Indy tuner wasn't able to program the new ECU, so I had to take to the dealership as BMW NA has locked down the software to program a new ECU and can only be done at a dealership. End of story, having a spare/2nd ECU will not work due to the data logs.

not to be a critic here, but I'm pretty well informed, and "having" a solution, but not sharing it,

1) makes no sense.
2) posting about it and putting your name on the forum, while BOSCH / BMW are certainly reading along, is even more stupid
3) either you monitize it, or you remain silent
4) is 99,9% sure bs

This guy is smart we are reading everything. Just FYI you cannot hide tuning we will see your DME has been manipulated.

As long as can Jb4 is we are good. 500 bucks for a tune and 125 for muffler delete. Easy 200hp gains less back pressure and better exhaust note. Plus the tune can calibrate for it and add more boost.
