I think the BMS guys have a 135 with the N55 on order....Should be interesting to see how they tune this motor. My guess is BMW will probably seal up that ECU box much tighter than they do with our current cars.

The ECU will be on top of the motor somewhere from what I read..

Expect an N55 tune from us. It will use the same PROcede rev.2 CANbus unit that we currently use. Just with a different harness and different firmware/maps. I

Of course there will be tunes. The question is...when ? I suppose it will have to pass at least the same amount of time that has passed until the first N54 tunes were available. Maybe 9-12 months after launch ?

Not even close. If we had a computer that offered full CANbus integration and all the built-in hardware we could ever need (not to mention all the knowledge we have now) when the N54 first came out, it would have only taken a few months to get to where we are now. I expect the N55 tune to be ready soon after they start hitting the streets. And fully enabled with all features (code reading/clearing) a couple of months after that.

Didn't u say it was going to be harder to tune this car compared to the N54? I mean right now at least the N54 is getting to the point that the tune is perfect, so if you do spend more time on the N55, we long term owners of the N54 shouldn't feel slighted at all!! lol

Harder yes. But certainly do-able with the proper tuning hardware.

They are probably going to seal it with GLUE!! lol I wouldn't be surprised if they have the ECU in one of those seals that once opened need to be replaced...

It's the old game, whatever will be developed, it can be hacked ...

However, I am curious to know more about the N55 capabilities. Hopefully BMW didn't downsize the strenght of the engine components to reduce weight.

IMO there is a reason why the N54 is further used in the 335is.

My $0.02

It can be hacked but what happens if they only sell the ECU seal or box to dealers only with vin specific..Nothing is impossible if your not able to get replacement piece for it! lol

You talk about warranty. Not relevant, if you don't care about it. Tuners developing a tune won't.

Right... but as much as i can see that being wrongly taken advantage of, I can see the desire as well....

- HPFP dies, do i deserve greif for having tuned my car ?? NO !!
- VANOS solenoid dies.... same deal !!!!
- wastegates rattle.... same deal !!!!

So yes.. it will suck if they have an obvious way of knowing if you got to the ECU or not....

My turbos are leaking oil btw... so i ordered a set from ASR... i'm not going to hold BMW to that one, not their fault.. its mine...

It's just too bad that neither BMW OR MANY OF THEIR CUSTOMERS are honorable enough to accept responsibility for their faulty design/hardware or for their modes (depending on which side you are on)

and once the trying to deny responsibility starts to happen on one side... it's forced on the other side.... really too bad.....

I've even gone through the effort/cost to repair things (like HPFP) myself to avoid them poking at my car... to avoid potential warranty issue later... (like VANOS died 'because you have downpipes' BS) ....

well, warranty claims MIGHT be raised for sure in case the same problems occur on untuned cars. in case U tune, it's up to U to cover repair costs, IMO.

I wonder why they moved the ECU onto the engine/intake block/manifold?

Anyways yes they will def be tunes out for it.

The real question is going to be the potential of the engine.
