S55 with locked DME question.

mwh2009 · 01-10-2022, 12:36 PM

So I have a 21 M2C, and it has the locked DME so no flash tunes currently available. (As all of us with this problem know)

Late last year, there was supposedly this company (person?) working on a flash tune and had a beta test going. Missiontuning.com

Went back to their website recently and nothing had changed. Does anyone know if anyone is actively working on this problem still? Or did everyone give up and go home?

When I talked to Carbahn, they (as mentioned in a few other threads) are beta testing a piggyback tune, and said that they would have the flash tune available about 2 weeks after someone else makes the ECU crack available.

I feel like the car that got left behind.

Plain and simple: People were jumping the gun claiming things they thought they had a path to, but didn't actually have for our DMEs. The only widely proven and released method is the one that Enabled debuted which is DME clone and swap.

Call me Beta! I just got my M2C 2021 back from Carbahn that was used for their piggyback development. I'm still waiting on the dyno reports but was told 520HP, not sure if thats at the wheels or crank or what octane but can tell you that this thing pulls so much harder.

Love it! In the absence of a flash tune, this is my next best option. Looking forward to your more detailed impressions and dyno results.

Honestly I love sumo data but more interested in how it feels, smoothness, particularly with the manual.

Have had tuned cars in the past, and "more driveable" or "smoother" have not been words I used before.

That is AWESOME!! I have had my Stage 1 flash from them for almost a year(Pre 5/19 DME) with ZERO issues.

Never needed more power from the dig but midrange and the pull all the way to redline is mental. Do you fell the same way with the piggyback?

Edit: BTW if they can do this same flash on the G87 as they did to this G80 in this CARWOW test, Jesus that car is going to be insane.

600!!!!! HP

21M2 · 01-11-2022, 01:51 PM

So mine is a manual and I haven't noticed any real difference in drivability down low but above 2500RPM it really comes alive. I feel like I have an extra gear.

600!!!!! HP

1780kg for the new M3!!! Wow that really is heavy. I thought my old F82 was too heavy, cant believe what its like with almost 200kg extra. So sad how big cars are getting

Mine is 2020, how do I tell if my DME is locked without buying a bootmod license and actually trying?

You can download and use ISTA+ to check the manufacture date of the DME.

So here are the numbers from Carbahn. Mine received the stage 1 Name: Screen Shot 2022-01-13 at 9.59.36 AM.png

It'd be interesting to see the full dyno plot. That way you can see when in the RPM range the peak numbers are being made. Is the dyno plot similar to the regular comp plot, just higher (so flattens off after 5500rpm), or is it more like an M2CS where it keeps climbing after?

Your not gonna see that number to the wheels on any piggyback other than a JB4. Carbahn is very conservative and your mainly paying for the warranty it provides. So numbers are lack luster. Rn I'm running JB4 on a 2021 M2C and on map 8 you will see 600+ crank hp roughly 560 wheel hp and 650 tq to the crank roughly 610 wtq. Only thing that's annoying about carbahn is there's 1 map. Why not purchase a piggyback where you can utilize 8 different maps for different styles of driving/fuel and air quality Rather then just a 1 size fits all piggyback !? If your going for warranty that carbahn provides go carbahn. If you want power and flexibility in all environments and fuels go JB4.

They are pretty similar TBH. Both are dubious in the way they make power. Timing cannot be controlled directly by the piggyback. They say you get a warranty still but I don't really understand that since the moment you build boost on one of those piggybacks, you'll trip all sorts of parameters out of expected bounds. Just my 2c; but if you REALLY want that kind of power, you need a proper flash tune and no expectation of warranty.

Negative, only parameters your tripping are torque load. Ecu sees stock boost if they were to pull that profile. Carbahn is slow. Always has been map 7 on JB4 will shatter any OTS flash and that's not even the most aggressive map. Just my 2c. I believe right now I'm currently the fastest 2021 M2 60-130 and only getting faster on Tuesday. All on JB4

. The fastest locked DME's in the world rn run JB4. Look at the new M's

JB4 is king. 15 years of RnD and updates behind the software. They are far from similar in terms of power.

Btw carbahns warranty comes from carbahn not bmw. So if that's your thing go carbahn. If you wanna be fast fast go JB4.

Carbahn released the M2c piggyback. It's $1k!!! + $750 for warranty???

A bit high considering dinan has there's priced at $580 with a few less ponies.

It's a hard sale IMHO

Yep I saw that - here's the link for anyone else who wants a look:

https://carbahnautoworks.com/product...f87-m2c-m2-cs/

I'm on the fence. I guess I'm not all that worried about the cost of the hardware, maybe a little more worried about being caught in the middle between BMW and Carbahn if I ever actually need that warranty.

I still have in my head that piggybacks just aren't as safe as the flash tunes. But I guess this is as far as they'll go for my M2C. I really wanted a flash tune.

Gotta decide if I'm keeping it or jumping to the G87 in a year or so.

If anyone does spring for this, please post your impressions!

f87CSdrifterential · 02-19-2022, 09:03 AM

Is the Carbahn warranty backed by a reputable 3rd party warranty or solely by Carbahn?

It is only for up to 4 years from the original date the vehicle went into service to match the original factory warranty. If you're outside the factory warranty the product itself is covered for 2 years, but not the vehicle itself.

https://carbahnautoworks.com/warranty/

That's how that reads, correct?

we bought our cars from the same place, now it's time to get our tunes from the same place 😎

I’d like to hear some feedback on this piggyback. I’ve had the stage 1 tune for over a year now with the flash tablet and matching warranty. Pre 6/2020 DME. ZERO ISSUES.

Does the piggy fix the flat spot from 5,200k to redline? In sport + is the throttle touchy from a stop?
