Also, not sure if i mentioned it before, but 125i needs a change somewhere in the air intake pipe, that is how euro tuners unlock the 125i in addition to DISA
Are u sure about this? The references for both engines are exactly the same... and someone told in the first page that no hw changes were needed!? I think they are needed in 325i... but not in 125i...

I have response from one chiptuner... 263HP / 320Nm :-)

I am not certain, but wintertuning or someone else has a stage 1 and stage 2 description, they both deal with the air pipe too.
Could just be an intake, but worth noticing if the pipe at the thottle body is restricted vs 130i

Also more info on the ECU software that you have from 130i

Exactly, I was reading and found that there is a 2nd (even 3rd in some chiptuners) stage for 125i/130i that needs the intake and exhaust manifolds to be changed.

But this is different to the 1st stage, where a 125i can be tunned into a 130i only through software.

I was looking for the references in REALOEM and the intake manifold and the entire engine ones are exactly the same in both models:

125i Engine: http://www.realoem.com/bmw/showparts...g=05&lang=enUS

130i Engine: http://www.realoem.com/bmw/showparts...g=05&lang=enUS



125i Intake manifold: http://www.realoem.com/bmw/showparts...g=40&lang=enUS

130i Intake manifold: http://www.realoem.com/bmw/showparts...g=40&lang=enUS


Best regards.

i don't know of any aftermarket off the shelf replacements for the 130i intake manifold.. you can do custom ones sure, but not easily.

Best regards.

3rd stage is them asking you to do exhaust, prob not worth it.

if 125i truly has same size pipe from airbox to intake manifold then all is well.

But intakes in our cars add good value as permanent charcoal filter is restrictive

A short bump up to the thread just to say I'm really happy with my tuned 125i. More than 2 years ago, it delivered ~260/270cv on the dyno. I've finally made the tuning with BND Unlimited, in Spain. But it was very hard... The RSA protection included in the ECU's software made us swear for several months until they finally were able...

Regards!

What about the DISA thing? 125i come with the DISA disabled and you have to activate or with just the software tuning you reach those 260/270hp?

Thanks!

Over at e90post, hassmaschine and I have been working on 3-stage tunes for the x25i and x28i cars. Successfully built a WinKFP flashable RSA-bypass and have files that should turn a 125i into a 130i and a 128i into a 130i. Will be released for free shortly.

Interesting - so to make sure I understand this, you would be installing the BMW factory map into the 125i or 128i ECU?

125i can be flashed to factory euro 130i software (I just change the powerclass byte so that the DME doesn't get stuck in limp mode).

For the US, a factory 130i flash doesn't exist. However, I studied other BMW files and was able to port all the 3-stage related parameters, so the end result is very close to what a factory 130i flash would have looked like if BMW made one.

Terraphantm this is an older thread, there are quite a few decent tunes out for n52. Perhaps take a look at this DME decoding thread

If you look, I was/am quite active in that thread.

Anyway the point was there was no way for individuals to flash an MSV80 without paying tuners hundreds of dollars. Now it is possible.

Good to know, thanks. Curious to hear results of anyone in the US/Canada that has done this....or better yet a dyno!

I plan to install Turner's performance software (SULEV N51) entering into this summer. Does anyone know what I can expect to gain?

Well if you are getting the Turner software that will "unlock" the 3 stage DISA, you should expect about 30+hp at the crank.

Did evolve ever come out with a tune for the N51?
The Active Autowerke "Turner" software seems to be the most reputable/used among the forum.

Never have gotten my AA tune to work correctly. Still messing with it, but so far a waste of money.

Would you recommend holding off on the AA tune then?
What exactly are you troubleshooting?
It seemed like the easiest option as I live in MA and Turner is nearby.
I somehow stumbled across posts in the e90 forum about issues with both the AA and BPC tune which makes me not want a tune at all anymore!
Can a tune really expose issues that are essentially already there but just "dumbed down" by the stock tune?
The car has 27,000 miles and continues to run beautifully.

Also what are the specs of your wheels and tires setup?
I am interested in some VMR beauties.
Include some pics if its not a hassle!

Can you send me a link to this thread? I have an N51 with headers and the AA tune and have no issues thus far - other than RPM hunting that occasionally happens at idle.

To be fair, putting the AA tune on my car lead me to find some issues. Vacuum leak and a bad coil. Finally got the car running 100% again and afraid to try the tune once more. The tune heightens everything so much that if your car has any small issues, throws the whole car out of whack

Specs on wheels:
VMR 18's. Powder coated Black Chrome.
Cont. DWS 225/40ZR18 in front
Cont. DWS 255/35ZR18 in back
