Get the cobb and get Peter to make a custom flash tune if you dont intend to get anymore bolt-on mods.

To get more than ~265rwkw with mids and tune only, OTS Cobb maps cant help you much. Their stage 2+ maps require a bigger FMIC as they think boosting the stock turbos to 17psi is ok without meth - not to many people agree with that.

Thanks.. But I have future bolt-on mods in the pipe line.

What I want is someone with a Cobb 1M to chime in and spill the beans.

Why not try before you buy?? If it is good I'd be keen.
In the qld dyno day, the 1M was running 218 and jb map 3 was running around 238. I would expect most tunes to perform around that on stock cars. Cobb have a beta tune running at around 18psi so I would doubt if it is on 4%.

Refreshingly, it wasn't a shameless vendor plug but a pretty balanced review I thought.

I'll post a link here once I find it.
I did want to wait till I disclose what tune I have picked but I ended up going with evolveR. The fact that if they are good enough for Beric, then it is good enough for me. I was leaning towards Giac, but not be able to do your own tune is a pain although Thomas from Giac has been very helpful so thumbs up to him as well.

Pointless looking at Cobb data on non 1M installs.

I know of a 1M running a Cobb in Sydney, but is OS at the moment, and have spoken to him about coming in for a uninstall then Dyno, then re install.... He hasn't given any indication if he is keen yet.

As Ian stated, if we can get a min 10% gain, we would be keen.

My car is about 265kw ATW with some boltons, so would hope for at least another 25KW..

I think 20kw is possible with stock cars, and that's what most companies claim - around 30hp. With bolt ons I am sure that would take it further.

Since I have got evolveR coming, and already have ESS tune - I am putting it out there for the vendors to sponsor a dyno shoot out . Just need a Cobb to complete the data.

Why change from the ESS? What gains did the ESS give you?

ESS is only a stage 1 tune and looks to have stopped development for the 1M. By the time I have all the bolt ons I would like to get a bit more gain from a stage 2 or in Evolve case stage 3 tunes.

I have never dyno the ESS, but probably a good idea to compare stage 1 evolve and ESS.

With PSS and the BBS Ri-Ds I no longer struggle with traction in 2nd gear - ie time for more power .

Otherwise, I am quite happy with the ESS - power delivery is smooth and it brings the redline to 7200rpm. Power didn't drop off as quickly as stock.

Do we know definitively that 1M N54 and 135 N54 are identical hardware?

Depends on the year of the car. Pistons and rings are different compare to my old car, but N54 from 1/2010 have the same as the 1Ms. I believe that as the M engineers work at the N54, they updated the engine, and it is passed on to all N54s. The engine block pre 1/2008 also have a different part number.

I have read that the older n54 have more forged parts than the newer ones.
Big posts on e90post etc if you want to read them.

Only difference between a 1m and a 135 n54 is better cooling, better downipes, higher boost and a m badge.

Cobb have taken down the dyno charts from their site. It was definitely only 4% gain.

ESS offer s1 and s2 http://www.esstuning.com/products/ES...-Software.html

Amazing how few independent before and after reviews there are

So the hardware is near identical. Therefore the optimum tuning solution is going to be the same for 135 (N54) and 1Ms, allowing for any differences in bolt ons.

So would a suggested tuning solution be a stack of Procede with COBB? Given what's available in the market right now?

In wonder how long it will be before we see a Rob Beck 1M or a single turbo conversion 1M? Can't be too far away I would suggest.

1m Dyno Day

OK guys i will make my dyno available for a 1M day, sorry only IM cars will go on the dyno but all BMW owners are welcome to come and give support and poke a bit of fun at the show and shine boys.
i will host the event some time around mid October so get all your tunes sorted


just a foot note, M button will be OFF sorry but these are very fussy cars on the dyno and have a mind of there own. unless i can find a way to turn off the nanny's but have the M on.

Please let me know names and tunes

Ian, that is Stage 1 and 2 for N54 engines, the 1M tune available from ESS is the same as the N54 tune Stage 2 but called Stage 1 for 1M...

1M ESS Tune
DirectFlash Stage 1 :
Top Speed Governor: Removed
RPM Limit: 7200RPM
Fuel requirement: 91US
Horsepower: 400 DIN(~294Kw) (Stock 335) - 390 DIN if used with stock intercooler(~287Kw)
Torque: 550NM
Normal whp range on DynoJet: 345-365whp


So Sparoz is correct, NO STAGE 2 for 1M from ESS.....

The ESS Stage 2 for the N54 is the stage 1 for 1M. The Cobb standard file is around 4% IIRC, but there are a few beta files around. There was a 1M review stating that it runs at peak 18psi, so 4% gain doesn't seem to add up.

It' not just a matter of pushing more boost through these tiny turbochargers. There are some smart people who have been playing with the N54 and the OEM turbos for a long while who feel around 17 psi is the edge of the efficiency for the turbos. After that you start making less power with more boost.

I'm sure Adrian could comment more if he felt inclined to do so, and Peter has tuned enough of them now to know.

For the newbies, it's not just about turning up the boost to make more power.

Yeah true, my bad. I skimmed through the intro and went into straight to the install and findings bit.

I got the pedals thanks, I'm gonna give the install a go now...I'll give you a call if I do need help
