ECU remaps for M235i

Anyone had an M235i remapped yet? I've googled it and found very few places offering remaps (and none of them are places I've heard of). I appreciate it is a fairly new model but surprised some of the major tuners haven't got a map for it yet.

I would assume with the car having a turbo it would get some noticeable gains from a remap, so I'm keen to get mine done but like I said I just can't find any reputable tuning companies selling a map for it yet. Maybe I'm missing something or maybe I've just not heard of the decent BMW tuners (as my previous cars that I've had remapped have been VAG cars - Audi, Seat, etc).

No one has cracked the ECU yet. Even DINAN has resorted to piggy back.

Advanced Flow Engineering (AFE) sold me a performance module with 2 piggy back plugs for my 2012 335i M sport and it will fit a M235i. . It's a safe tune for $470 and I defiantly notice the difference. Takes 20 minutes to install.

No ECU flash for now ( it is not looking good either since Cobb has gave up and Dinan decided to go with a piggy)
Lots of companies offer piggybacks Burger Tuning (JB4),AFE,Dinan,etc...

Yes there's a chap on babybmw here in the UK who had superchips on his M135i [same engine as M235i].

IIRC he resorted to JB4 in the end as he wanted more flexibility to tweak his tune.

I'm sure I read on here that a tuning company had cracked it but you have to send them your Ecu! The JB4 is what you need.

The ECU has been cracked. LEIB engineering in Germany cracked it. https://www.facebook.com/Leibengineering?fref=ts

They have 2 different options, you can either send in your ECU (a bit cheaper) or they can send you a completely new one.

Anyone here tried Steinbauer p/back for Mx35i ?

Seems to get good reviews on German forums.

I am yet to see 430 crank hp from FBO N55 on regular 98 fuel (us 93 fuel). Since crank hp is converted from wheel hp i am more intrested in wheel hp numbers. And even more so in 0-200kph or 100-200 kph or quartermile results.

Maybe a post 2013 july build N55 with the newer turbo can get 430 crank hp if it runs a heavy ethanol mix or meth. I doubt many germans run around like that. 380/390 crank fbo on 98 seems more reasonable to me.

But both mannhart and acs dont offer real ECU tune, only boxes as far as i am aware.
