I'd love to bump up the M2c when I get mine to 460 Hp like in the M3/4 CS models especially using a factory "safe" tune, but I'm not sure how this works.

Who makes this tune? Is it flash or piggy? Is it really exactly the same code as the factory CS? If not, then how do I know it's the same level of safety and engineering as a factory M3/M4 CS?

Does the M2c have adequate cooling to make this tune safe? Does it have enough air flow at intake and exhaust ?

Also is your warranty (engine) toast once this is uploaded?

You should read Bootmod3 and BPM threads under engine tuning. They basically took the factory DME file of an M3/M4 CS and modified in a way that it can be flashed into any other S55. These are the two tuners that I know offer OEM CS flash as opposed to a CS-like flash. All your questions are answered in their main threads under the F80 engine sub-forum.

Pretty much! Even though new flash tunes come with various methods that make tracking tune related metadata more difficult (e.g. no DME drilling, flash counter freeze etc.), there are still many other ways BMW can actually find out that you tuned your car and even tuners don't deny this. IMO, if you are tuning, you should also be ok with the consequences. If I damage my engine due to an aggressive tune, I wouldn't blame BMW for denying my warranty claim. The thing with CS tune is that it's an OEM software that is used on the exact same hardware in the M4 CS. If something goes wrong and you tell BMW that you were running a "safe", OEM tune that is used in a CS model having the same hardware, they still won't care and probably decline warranty coverage.

It would've been hilarious if BMW dropped an Easter egg with the M Driver's package that not only increased the speed limiter but also gave you the m3/m4 tune without telling anyone.

Yeah. I’ll prolly stick with Dinan. They back their tunes with 4yr/50k. It might not be the best out their in terms of power but they are kinda like apple. Their stuff just works and you pay a premiem for support.

Even though it might still be tough to have them cover it if something went wrong at least I have that Avenue vs nothing for the other tuners.

I agree. I'll probably drive it around for a bit and then go Dinan if the option is there. I waited until out of original warranty to get my s4 to stage 1. I don't see myself waiting that long on this. I just want it de-tuned which I'm sure the Dinan flash will do at a minimum.

Just went through every one of their threads and also their webpage.
Nothing about a CS "Factory Tune" anywhere.

Please point me in the right direction, Bootmod3, ProTuningFreaks have no reference to a CS tune anywhere.

Starting reading from here for bootmod3, you'll see I asked a similar question back then too.

And this is for BPM. Although it seems too long, try to read as much as possible. There are some great questions and answers in that thread. You can also PM the tuner himself.

This is a great conversation - I have been interested in doing this on my F80 ZCP and would consider it on the M2C as well.

Is there any consensus as to which is the more preferred vendor? I haven't read those threads in a long time.

You can tune the stock S55 to 500hp without the water injection system; BMW implemented it into the GTS to help further cool down the motor and ensure longevity..

It's an old trick they used in race cars, it's sort of a safety net but not necessary..

I say you're safe tuning up to The 500hp Club without the auxiliary water-cooling system.

Not if you're tracking the car.
I might be most interested in the CS tune for that reason.

You guys can also have a look for premium german tuners offering guarantees and are respected also by BMW.

AC Schnitzer is for example one of the best, have also international dealer network. Also G-power or Hamann are very good...

Touché

But if you just want an aftermarket tune to push 500hp, just for bragging rights and not is really going to beast on it on any track, just some some street driving, I think you'll be fine..

As we know, the M2C has the PnP M4's cooling set up, that's more than sufficient IMO.

Just a heads up, the M3/M4 forum is full of S55 tuning info. Endless amounts of dynos, firsthand reviews of tunes, etc.

Both BM3 and BPM do exceptional work and provide top notch support for their customers. There are significantly more BM3 customers due to many reasons such as:

-They started working on F8x platform way before than BPM
-Their stage 1 and stage OTS maps seem to outperform most other tuners' stage 1 and 2
-Their platform is very unique. They allow individual tuners to deliver their own tunes via the BM3 platform. For example, if you know an experienced tuner, he can create a custom map for you by using BM3 platform
-They offer a lot fo customizations such as adjusting burble aggressiveness, enabling/disabling cold start, turn on/off catless downpipe check, enable disable top speed limiter, enable/disable rev-match in comfort, sport, sport+ etc. These are really important as you can just select/deselect whichever you want in their UI before flashing your map and you can change these settings as many times as you want. with other tuners, you tell them what exactly you want and they send you a map with those features. Let's say you want to disable cold start later on, you'd have to contact the tuner and he would have to send you a new map if you were using any other tuner than BM3.

BPM may not be a as popular for F8x platform yet but they have a huge customer base from E46 and E9x folks. I know couple E46 and E92 owners who are in love with their BPM tunes. Mike at BPM is extremely knowledgeable when it comes to coding, flashing F8x platform. He has a repository of not only OEM ZCP, CS, GTS maps but also every single I-Step version that your car can possibly have. In other words, returning back to stock and locking the DME safely is not an issue with BPM either.

Although it seems like BM3 is the best option here in terms customizability, you can't really go wrong with either. Also, I want all OEM setup; in other words, OEM burbles, OEM cold start, OEM CS map so BPM would satisfy all my requirements as well.

Cntzl what does “support” mean. If their tune messes up my car are they gonna cover the repair or does “support” mean they just have good customer service and pick up the phone?

Well don't confuse "support" with "warranty". No tuner provides any warranty with their product except for Dinan and even in that case good luck getting them covering big engine failure as there are some stories about them as well. Support means if something goes wrong with flashing, or if you need map specific changes they address it pretty quickly. They will not cover any repairs.

I always think of it like "IT" support, rather than "hardware" support.
