Does this mean there's hope for non-piggyback tunes for regular F10's?
Do they share the same ECU?

Every tuner can do it now. CMD has cracked the Tricor chip and has been selling the tool and tuned files to European tuners for several months. US tuners are just starting to get the needed plug-in. In four weeks every last local US tuner will have it.

This will not be a bargain tune like the piggy backs. Expect prices around $2,000 or maybe even higher.

Here is what they are doing in Europe right now:

2014 550i with the N63tu engine got a stage 2 tune that made 575 HP.

Stage 1 tune makes 540 HP. A gain of 90 HP. That is nuts and I want it now!

I don't understand why we are several months behind on this.

All the tuning tools you need to do this cost about $15,000. I'm thinking about just pulling the trigger and ordering everything. It is a ton of cash. I have done this with Porsche Turbos, the 996, 997, 997.2. My 2011 Turbo S is one of the fastest out there. Just with my tune and exhaust it is faster than a GIAC car with $12,000 in additional hardware.

It would be great if I could find ten guys who want their F10 tuned and donate $1,000 to the cause. The files already exist on the tuning file exchanges. They cost little. US tuners will most likely charge $2,500.

Guys, let me know what you think.

It appears you're right

$900 is worth it, if gain is on par with BMS tune and you get flash and reflash at your own will.
Anyone running this?

535i only has one ECU and is the old ECU chip. That is easy.

The new thing is the 2014+ 550i and M5 (N63tu engine) with the dual ECUs - which have the Tricor chip. That is a whole new animal.

Actually, companies like COBB have stayed away from F series n55 cars because the ECU was much more complicated than those in E series cars.
Didn't know the 550/m5 had dual ECU's.

But..... The ZF transmission in the F10 535i doesn't have much overhead in terms of additional torque handling capability (332 foot pounds is the stated max torque I believe) so be careful. I'm sure that number is a little conservative, but a big torque boost could spell trouble.

I would say 90 HP and a Dinan power train warranty is worth the extra cost.

Put me on list.

Well damn about time

[550Reasons]

I believe theres a guy down in Miami that does the tunes on M5/6 and 550i, I am waiting to get my car thru the care package then off to him for coding and tuning if price is right.

Do you think the reason bmw holds back on the 90 hp is to keep the motor compatible with the tranny?

In other words, if the tranny was spec'd to handle the extra torque then bmw would up the available hp?

all i know is the meth injected M5's have been burning DCT clutches.

BMW engineers match the transmission to the engine. They understand the powertrain limits very well, and any "tune" they introduce will stay well short of those limits - obviously for warranty purposes. Any tune they introduce in the U.S. would also have to be 50 state emissions legal.

I was talking to a BMW aftermarket engineer this weekend who said BMW is getting really serious about tracking down mods. As an example he said the new M3/M4 tracks every modification made to the DME and sends a notification to BMW informing them the car has been modified.

Got it. Once the early computer revolution took off with solid state technology or similar (SLT), IBM suddenly found that a computer half the size was twice as fast. That didn't sit well with marketing and senior management. So, IBM actually inserted NO-OPS (extra cycles that performed no work to slow it down). Smaller computers just had to be slower.

Well, that's kind of my point. We know BMW understands the secret to gaining that extra 90 hp since Alpina does it with the b7, right?

So, do you think BMW intentionally de-tuned that extra 90 hp in the stock motors? Why? Because (1) the extra hp/torque would exceed the limits of the tranny in most stock vehicles; or, (2) BMW wants to give Alpina (and others) the ability to tap the extra 90hp without having to modify the motor's physical attributes too much?

If true, that bugs me to know I currently have 90 hp just sitting there waiting to be tapped with an ECC firmware update.

How long will it be before BMW offers a service where the customer goes on line to "lease" the extra 90 hp for a weekend for $1000. You go to BMW's website, login, pay for the 48 hour lease, and then BMW (wirelessly) connects to your vehicle, uploads the ECC code or otherwise activates it. After 48 hours, the old ECC Code was restored and your car loses the 90hp. The $1000, for example, would go toward BMW having to deal with increased wear and tear under its warranty.

The way I read that, the N55 Flash Tune is no HP gain:

"*This is a flash to improve throttle response and shifting performance, it is recommended for Turbo cars to get our Tuning Box kit instead."

For HP gain, you still need their Piggy back Tune here:

http://www.vrtuned.com/shop/vr-tuned...4ekdnulgk0ebk5

And I would assume that the Piggy back Tune for $700 would also improve throttle response and shifting performance, so I fail to see why someone would pay $900 for the flash tune that does less and costs more.

The powertrains are designed to deliver what they deliver reliably, at a certain price point. More power requires more expensive components (e.g. Forged internals vs. cast in the engine and transmission). You mentioned Alpina, but keep in mind those are not stock engines, they have high performance internals designed to handle the increased power. I was in a shop last weekend to get coilovers installed and the guy had a Customers blown M5 engine torn apart in the process of being rebuilt (rod bearings were thrashed). I asked him about the cost - 25k for a new M5 engine. And for a new N55, I asked? About 8k.
As for the $1,000 weekend, I'd rather rent an M5 for three days for the same money
