I do agree.... what about reliability? I'm out of bmw warranty so I could do the upgrade but I'm afraid of breaking something..

3. Once you have a 125i there's the option of "BMW M Performance Power Kit for BMW 125i". (I would consider only this.)

Listen guys, tuned or not tuned... cars sometimes have malfunctions.
If you don't want issues with your car, don't buy a car and do not tune it!

However, a stage 1 flash usually stays within the limits of mechanical components. (at least it does with our tune)

[kabamaru]

Totally agree.

[xenos]

I disagree. The case is not 0 or 1 here. The turbocharger can work more efficiently than factory settings, but to some extend. After this "limit" you just create troubles without getting much more power. That's why I have asked if you know the factory turbo boost and the improved one, to the various rpms (but got no answer! ). I prefer 10 hp less, than 2 years off the turbocharger's life.
The most easy thing for a tuner is to give you very high boost + huge overboost, as you will think that your car is a ricket. Think twice...

The turbo will eventually create a faster Wear and Tear as well with other components! For Greece especially a further modification/tuning is required (cooling mostly) to sustain such use! The 114i and 116i has a different oil cooler from the 118i which probably would do a better job! Possibly checking the part number of the turbo for 125i with the 118i and 116i could provide some better info! If the parts are the same then yes it will sustain the power! i know this answer is not what you may want exactly hope somehow it helped!

If you go to a reliable and serious tuner all those parameters are expected to have been examined so as not to set the engine in danger. I owned a couple of tuned turbo cars in the past and never had any problem. Even with bigger turbos some engines can withstand a lot of power without the need to open them and change the internals. I don't know though which is the limit for the bmw 1.6 turbo engine but assuming that in other cars (mini cooper works, peugeot rcz) it is capable for over 200 hp in factory setup i don't find it illogical to produce 220 hp without problems. I agree that for the hot climate of Greece an oil cooler and a bigger intercooler is better.

It is illogical! The initial part of the exhaust is also different! Dont forget in rear wheel drive power is lost when reverse the engine to Front and they reach the tin cans you mentioned! Further BMW is a heavier car compared to those tin cans!

Going in such tune and takin in consideration that you want to keep the car for as long as possible it will require extensive modding, changing a lot of things including the turbo! Think it this way if your car goes 230Km and you put tires of speed rating Q and not T or W what would happen to them!?

How does the boost map look for your M135i Stage 2 tune? What boost (psi) at what rpms? I am also interested in target AFR.

- Thanks

that's not so easy a tuner with a reputation will never go over his safe limit, why would he? There are too many risks involved!

Hi Harkes,

to many people on the forum send us a mail @ info@br-performance.com for information.

Too many people? Maybe you could save yourself answering quite a few emails posting info here...

I have been in email contact with Bruno before but we misunderstood each other a bit.

I really just have one question: Can you make a map that target 14psi 4000-7000rpm with AFR ~12? Ill be installing my Pure Stage 1 asap and send my ECU your way if you can

There is 14.5 ish psi limiter (1 bar) in the dme. You can run that till 4800 rpm. Then boost (load) will go down. Unless that limiter is found and removed there is not much one can do with a flash.

I see most of you guys run our tune! I hope it's great!

Team BR-Performance

Ι am tuned by you also 2 months now and i am very satisfied with the results. I would like to see any recent diagramms with measures for my model(116d 116hp ->150hp). what about the turbo pressure i read a lot in here and our clima in Greece gets realy hot in summer. I thinki now it may works from 14 to 18 psi but i havent measured it.

[chaddy74]

Thanks for chiming in !! You must know first hand

Yups Also a F20 M135i with speed limiter removed can be fun on the german autobahn!

[yalim7]

Hi everyone, i'm about to get an ecu tune for my F20 118i, stage 2 with supersprint exhaust system, Forge intercooler and Arma carbon intake, but i don't want a custom tune made by a person like people usually do in my country. Looks like the only option is Superchips' tune since its the only brand here. Anyone here used or using their tune? Any feedback or recommendations? I know about br performance but seems impossible for me to send the ecu. Any thought is appreciated, thank you guys!

[ovekvam]

I know several people who run Superchips tunes on other types of cars, and it seems like a serious company who know what they are doing.

[selçukdal]

does anyone knows how many litres are f20 116i intercooler?

do you know why boost cannot be controlled above 4800rpm?

[chaddy74]

They cannot find the secret protection encryption in the ecu tables to allow boost in these areas yet ! BMW have really locked down this hardware thats for sure ! It will only be a matter of time before they can tho .... but who knows when that will be.

Are't the std / tuned graphs supposed to cross each other the the same rpm?
