I don't think it's possible to downgrade via OBD once upgraded.

Not sure about the part regarding the production date. Not something I would wanna test and find out I always tell my service advisor not to perform any software updates without letting me know first and so far I haven't seen or heard any mandatory software updates in the US. Considering Alex@Alpine and BPM already support flashing on the latest software via OBD, I think it's just a matter of time BM3 will release their own solution.

Here's the full quote from Alex:

The bootloader on the post production 07/2018 vehicles if updated becomes a updated version of the current bootloader. I do not think it was made with intentions of blocking tuning (or maybe it was as you can not downgrade it once upgraded.)

Answer to your question, yes I can still tune with the later bootloader so none of current or future customers are impacted by this update.

The way I read it, M3 and M4 cars built in July of last year are also affected. It's only the prior builds that don't have their bootloaders changed with the update. Because of how quote is phrased, I can't tell if the same applies to the M2C or if all of them will be locked out by an update.

Litchfield posted on FB that they cracked the latest BMW DME update on the M2c.

This BMW M2 Competition came in for EIBACH lowering springs, a catalyst back Remus exhaust, Eventuri carbon intake kit, our Stage 1 remap and crank hub fix.

Our Stage 1 remap lifted power 110bhp & 111lbft from the claimed 410bhp to 520bhp and torque increased from 406lbft to 511lbft with the internal power meters recalibrated to suit. We carefully set these up to provide a nice smooth torque curve to feed the power into the rear tyres which helps provide better traction.

This particular car had the latest BMW firmware which locks the normal OBD tuning but we are able to reverse this thanks to the latest EcuTek software, all without removing or opening the ECU!

This already great car is transformed into something very special 🙂

If you have an M2 Competition that you would like to improve get in contact.

on one hand this gives hope, on the other hand... gotta bring it into them in the UK. Maybe I can have the boat stop and drop my car off for them hehe

[gmazet]

so from the website https://www.litchfieldmotors.com/bmw...ower-upgrades/

it sounds like they basically have you bring it in and they roll back the April 2019 update (as opposed to having over come it).

We are able to simply reverse this to allowing OBD programming, but we do require the car or ECU to be present

Remote Tuning Option*
Stage 1 ECU tuning with Ecutek software, Bluetooth interface and programming key
£795.00 ex VAT
£954.00 inc VAT

* Late model BMW M2 Competition models have the latest BMW ECU firmware installed at the factory (~March 2019) or may have been subject to a Main Dealer firmware update. This new firmware version removes the loophole that allows direct programming through the OBD port. We are able to simply reverse this to allowing OBD programming, but we do require the car or ECU to be present so we plug in and unlock it (no opening is required). Once completed we can continue to tune remotely as before.

This need for speed bug is crazy...I'm already used to the Stage 1 flash. I think I want more!!!

The 7/18 date is when the newly homologated S55 version was released for M2C M3 M4.

It ties in with the OPF production start in the EU and new non OPF version elsewhere just prior to the new WLTP emissions stuff which became compulsory from Sept 18.

I'm at Litchfield next week for their hub capture so I'll have a chat about this issue with them.

Yes I'm lucky as hell, they are just an hours drive from me...

Any update bm3 unlock for the new eu?

[m20e3087]

I am taking mine for 10K service next week, should I lock the DME now to let the car adjust for few days or will I be able to lock it morning of the appointment, so can't trace back.

Edit: locked the ecu to stock. had my 10K service done today, told the guy I had a urgent appointment and I have to leave in an hr and told them I don't need the car washed. I was out within 45 min. Didn't mention anything about software updates. Came home and flashed it back to stage 1.

BTW my appointment was first thing in the morning when they opened at 7AM and I was the first one there.

Not getting a reply from my previous post - thought it more pertinent to try on this topic!

I am currently running a Map from a UK tuner on my M2C which is all cool.. But i prefer the flexibility of going to bootmod3..

Question is i have the stock file which i can re-flash and is what i am now running.

Now this stock file is back on the car. Can i go ahead and re-flash using BM3?

Any help and advice appreciated.

[doughboy]

Should be fine, whatever is on your car BM3 just records as the stock tune.

The when you flash a new map it saves your stock one on the cloud system so you can go back anytime.

[kyoshi]

OK cheers will go ahead then

Anyone running stage 2?

I ran it for awhile (91 oct) Pulled like a freight train in 4th but needed lots of boost by gear to not overwhelm stock tires. back to CS+ until i upgrade tires.

My M2 has a very clever variable boost controller. I can automatically control the engine output myself depending on weather conditions and grip etc.

It's called a "throttle pedal". Rather than a ON/OFF throttle switch, if you press it less than to the floor it gives less than full boost and avoids the inevitable wheels spin in lower gears.

Amazing idea... not sure if it will catch on though.

ya heard guys pedaling e85 on stock tires too. logged it once and had wheelspin in 4th so
CS+ works good for track use on stock tires

The car already comes with mapping which limits torque by RPM, boost by gear just allows you to further increase that already existing functionality.

Having the ability to fine tune the amount of torque delivered at any given % of throttle is incredibly useful and is used by Formula 1 as an example.

see 3:50:

The idea that you can increase the window through which you can operate torque output gives you MORE control, not less.

For street driving it may not be important.

I'm looking to BM3 my OG M2. Is stage 1 worth it or should I upgrade my DP and FMIC and go straight to stage 2?

[mcvaughan]

Don't if concerned. Go with your gut.

I'm considering BM3 just for adding Rev-Match with DSC Off. And am happy with that added power alone. Can always add stage 2 later.

Cheaper and easier to learn how to heel toe downshift for the track.
