From what I've read I do believe that BMW has put more tamper protection into the DMEs and it will be more difficult to modify them. But, you know it will be done eventually, and isn't the tune you are running proof of that? Hoping to learn from your more informed experience, thanks.
Yes, they can tell.

You are 100% correct. Btw, I saw your post about PP. They run the same software that I am talking about. Same developer. We have mutual friends. Very good shop.

You got it. The engine can be made to supply a lot more power quite easily, however the DCT transmission will not handle it. The Dyno numbers you see are not reliable. No one uses the correct parameters on this car. It is a different animal than previous cars and other BMW turbo models.

Yep. It would seem backwards I suppose. I am not claiming that mine will not void warranties. Fact is that I do not know. I do know how BMW feels about Dyno runs. Will it be an issue? Who knows? If it concerns you then heed it. If not, do your thing.

My software, DP and exhaust will still pass emissions. That was my biggest concern frankly. All I will tell you is that nothing I am doing is likely to be a real big issue for me. again, that does not meant that you will not have warranty issues. I don't know. You would need to ask BMW.

I wait for the day that BMW doesn't void are warranty for tunes,running dyno tests, exhaust, wheels, ect. And they give us the top speed of 200mph and let us use launch control as much as we want. That will be the day....

Honestly, I am not going to discuss the software on my car publicly on here any more because I am not going to engage anyone as to validity any longer. Very frustrating. Yes, they have made it hack proof intentionally.
Are you ok???

Well it is kind of like you spewing out this "opinion" that you formulated from nowhere. So to firm up the question about Dynos and warranty issues, and to eliminate any sense of speculation and questioning, you will be able to check with your BMW dealer shortly as BMW has officially implemented the policy and is in the process of releasing a bulletin to US dealers. The only thing I cannot tell you with certainty is whether or not they will be able to apply warranty voids "retro" to the time at which the policy was established.

There you have verifiable fact. No need for further speculation. Unless this decision is overruled for some reason, you will be able to verify this very shortly with your dealer.

Btw...I wonder if you can surmise where policies like these are born from? Where do you think BMW and other manufacturers gather information that gets them saying "hmmmm"? Hint: You don't have to look far.

I am definitely not an M engineer but my Dyno processes information comes from someone in a position quite a bit beyond "engineer" these days. As stated before, I know this is a no win discussion with most people on the boards. Believe what suits you and disregard the rest but don't discredit information useful to others because you have randomly dismissed its validity. Some people really do know things and are willing to share for the good of others, which I believe is really the spirit of the boards

Sure thing.
I believe it when I see actual proof from you on many of your "claims"
BMW can certainly tell any change in parameters/resistance/measurements and if they don't correlate in a way it makes sense to them (ie tunes/piggy back etc) . They also have ways to log certain information in spaces inaccessible to tuners (in the past certain tuners would flood the DME with thousands of exhaust flap errors to "push" out other logged events) . As soon as your car is connected to the BMW diagnostic system and a case is opened with HQ they will see the data (the dealer can't do anything to intercept this process , besides not to plug in your car) .
I wonder how you will distinguish from a car accelerating or running on a (properly setup) dyno. But than again you know so much none of us mere mortals I will wait with baited breath. In the event of real proof I am happy to eat my own words (ie your mods , warranty etc) ... until them I will be skeptical. Being vocal and stating the same over and over again doesn't make it any more true. Case closed for me for the time being.

So just to save you some legwork ... I am fairly certain the top secret items ColdList is talking about are parts developed by the German tuner Noelle . They are a great shop and have a very good reputation.
However they are in the same boat as any other tuner in regards to warranty / coverage , ie aftermarket.
They have a program for the M5 available at
http://www.noellemotors.de/en/produc...e-s63-tue.html
For their stage 2 and 3 you will also buy new downpipes and rear mufflers developed by Boyes who also do contract work for BMW.

You should crawl right back under that rock. If you really had any clue where this same from you would be red-faced.

Honestly, you just stated correctly above that "They also have ways to log certain information". THIS is how they can tell. There are tables that are compared. The freaking Dyno specs on this car are documented in a 26 page book for goodness sake. How naieve can you be here? Yeah, it goes DIRECTLY to BMW Germany. The dealers have a heck of a lot less knowledge and CONTROL than people expect. At least you and I can agree on this.

Your repeated DENIALS of everything don't make THEM any more credible. You pulled all of your negativity out of your butt, throw it around and declare "case closed". Perhaps you should apply that thinking to yourself before discrediting things. I wouldn't repeat any of this if guys like you didn't make unfounded comments that come from absolutely ZERO insight.

If you don't believe things then move on. Really comical. I am willing to bet that you are over there doubting the BMW downpipes and exhaust I mentioned too. Funny stuff. Held them in my own hands. Can't think of better proof. As soon as I get permission I will post some pics so you can have validity.

I really don't find it very productive to be this nasty with each other but I am not going to take abusive lashings either.

Listen, as I posted on another board, I know by writing this stuff I sound like a freaking know it all and someone who thinks he knows everything. Truth is, I am a regular really nice guy who happens to have a load of time on his hands and building these cars has just become a hobby of mine (I use the term "building" loosely. To me that means buying stuff and having someone else install it). I know NOTHING about the inner workings of the car. Heck, I couldn't change my oil if I had to. I just happen to have a very unique association with someone who is an upper echelon guy in relation to BMW Germany. He is responsible for many of the technologies in today's BMWs. I take his word at face value because really I cannot imagine questioning him. Other than that, honestly I couldn't "prove" anything except that I personally receive the products and install them on my car and the car is exceptional. The information about Dynos I have seen as well. The BMW Dyno thing and warranties I was told about in advance and today I got word that it went through. If it turns out to be bogus information I will gladly eat my words too. It just makes no sense that it would be, coming from this individual. Nothing in the past has ever proven to be inaccurate. He is so highly reputable and passionate about these cars. Believe me, as a car nut, getting to speak to him the first time was one of those "magic" moments in life.

I know it is hard to believe things that people write sometimes on here and frankly I really understand the cynicism. I would likely have the same initial thoughts. I am sure you read the first thread I wrote about my software and then saw Manhart jump in and say "It does not exist". Then I jumped on him for questioning mine and told him that his did not exist. We ended up on the phone together and really hit it off. During our second conversation, we discovered that we had the SAME tune. So does ACS, PPI, and several others. Got a good laugh out of it.

Honestly, I don't want to create tension between you and I. Just PM me anytime and I will gladly connect you with the products if you want. I am very happy to help. I hate that I can't share information that really many people would never have access to, and be sort f chastised for it. I know that is probably not your intent and from my standpoint no hard feelings whatsoever.

I guess you guys should just stand on your board reputation and the proven accuracy of what you've posted in the past...

Or anyone can look at your cars and the modifications you have accomplished on them (and help other board members with), and get a sense of who really knows BMW, and the M5, best.

I am new to this board but not new to the competing board. I openly will assist anyone in obtaining any of the products I have mentioned. Really doesn't need to be done in some kind of competition. I don't care who knows more. Neither of us are really that important in the end. I will however put my car side by side with anyone FOR FUN. :-)

Thanks for being a voice of reason.
Just to add some more info on the Noelle story I just added some info and pics to the thread at

although I doubt that its an issue to dyno the vehicle YOU own.

its actually really easy for BMW to see that the car was dynoed with a simple check of the ECU through the data port.

If a car is dynoed there will be a huge difference in the wheel speed sensors which can easily be verified. Rear wheels going 155mph while the front wheels are stopped. (or are rolling 5mph). Wheel speed sensor's are continually being monitored while the car is running either way.

Yep. Agreed 100%. A breeze for them to know.

Not sure when you say "YOU" if you mean my car. It I would certainly have the same issues. Just not sure how much that matters to me. It will definitely not get in the way of me making the car what I want it to be. If I am going to spend this much on a car I am going to get every bit of enjoyment that I possibly can. Being carefully cautious though.

Coldlist, I'm not sure this correct way to PM you but I would very much like to have a discussion with you regarding the flash, exhaust, and the down pipes. I have trade my E90 M3 in and now the proud owner of a white F10 M5 beast and want the assistance and advice you seem to have

The ECU (MEDV17) in the M5 is not new and is tunable. The only problem is cracking the RSA signature when writing to the ecu. Seems like only a couple of tuners have managed to do this. I am sure it wont be long before everyone is doing it.

Reading the ecu is easy as is writting but you get the RSA sig wrong and the car wont start.
