Coding SPBR on an 2NH equipped vehicle

I'd be interested in coding the SPBR option (so the coding that comes with the MPerformance brakes) on my car which has the 2NH option.

As I understand from reading the other threads, the MPeformance and MSport brakes are identical, save for the slotted/dimpled rotors.

Also, from what I gathered, the SPBR coding improves the brake feel.

So I have a few questions:

1) Can someone confirm that the only difference between 2NH and MPerformance brakes is in the rotor's appearance. (brake lines are the same, etc?)

2) Did anyone actually code SPBR on a car "only" equipped with 2NH?

For those that answered yes to 2) :
3) Did it actually improve brake feel?
4) In regards to coding, was it simple a matter of adding the SPBR (and no other changes) ?

Hello

Question 1

yes there just drives that are different

question 2

yes there a better braking


it will also manually change the size of the disks in the DSC file

Hey,

I'm talking about the M-Sport brakes which come on the 335/435i/d.
These are 370mm - the same as the M Performance ones - so there is no need to change rotor sizes in the DSC.

http://www.turnermotorsport.com/t-br...fferences.aspx

I'm interested if besides appearance (the dimpled/slotted look) there are other parts which are replaced by the MPerformance kit (like for example the brake lines?)


From what I gathered so far, the SPBR coding will change (increase?) the pressure in the brake system and alter the brake pedal feel.
What I want to know is if anyone did the coding without having had the physical brake "upgrade".

If you read the DSC data :

SPBR does not change the rotor dimension

If you put in the FA 2NH the rotor dimension are corrected by coding.

(i talk about M performance retrofit kit)

I don't konw why

My car with a stock 340-330 system, after a M performance retrofit kit have only a SPBR HO WORT Coding (DSC data are with 340 and 330 rotors but installed 370-345 rotors)

That's really interesting.
Does this mean that SPBR should also be coupled with the 2NH in order to have the correct sizes?

Concerning the MPerformance brakes...did they come with new brake lines (stainless steel)?

I'm asking because I'd like to add the SPBR and since I understood they increase the pressure in the system, I don't know if the standard 2NH brake lines handle it.

Lastly, what exactly does SPBR modify?

Thanks
V

SPBR brake Ho WORT code, modify only the first 2 lines of DSC coding structure (menu 3000)

I do not remember the particulars (sports.... 18 etc etc)

The big question is :

THe DSC unit (hardware, pipelines and ecu) is the same from standard 335i F30 to a 2NH embedded F30 335i ?

Sorry anothe Things :

With only SPBR coding (from dealer) the Mperformance brake system work perfectly

With SPBR+2NH coding the feeling is not the same (very aggressive and less modular)

Hey buddy.
My first post here.
Not sure if this is allowed.
I coded SPBR but in the DSC menu i can only see the front disc size but not the rear disc size.

Did i do anything wrong ?

Sorry to resurrect old thread. But I wanted to make sure about the SPBR coding.

For non 2NH cars: SPBR + 2NH or ONLY SPBR?

I have successfully VO coded SPBR and DSC, but it does not show rotor sizes in the drop down. Also, I only see c_variante_bremsscheibe_vorne (front) with 'initwert' setting but nothing at all for c_variante_bremsscheibe_hinten (rear). It just says UNBELGT it the field where the hinten should be.

It is my guess that the option to choose 370/345 rotors sizes come from coding 2NH option (I have not done this to prove it).

Can anyone comment?

When dealers install M perf brake kit - they code via Ista+ by doing "m sport brake retrofit".
That adds SPBR to the HO WORT. Same place where MPPSK is. That's it. I just went thru this. Car was latest I level and IsTA+ went thru coding a dozen or so modules (at Least the status check marks) and upon completion - option list had SPBR. Took about 10-15 min.
That's what official instructions say to do. Dealers can't do anything else.
SPBR does not change the rotor size and most likely it's a moot point as it's used for spare part identification. And in case of SPBR - that is only one option. I think 2NH had different rotor sizes based on which model it was (2er or 3er).

Were you ever able to find out how to code 2NH? I encountered the same issue with only seeing the front rotor size with only initwert as the option and no rear rotor size. I think you may be getting somewhere with it being related to the fact that both our cars were not equipped with 2NH prior to installation.

I have reached out to shawnsheridan and few other members that have posts regarding this matter. The definitive consensus is to only code for SPBR and not both. If you have a 2NH from factory and coding SPBR, you would need to remove 2NH. This is because when you code SPBR, even though you do not have the drop down for rotor size selection, the default values already reflect the 370/345 rotors sizes, as there is only one sizing for M Performance brake rotors. 2NH coding allows for drop down selection because rotor sizes vary between models for the same 2NH option (ie. 2-series blue brakes are 340mm). So technically for those with 2NH cars with 370/345 rotors (3,4 series) from factory, they can remove 2NH and add SPBR and it would achieve the same result.

Also, there is a member who tested SPBR and SPBR+2NH, he mentioned that when coding both, the braking felt unnaturally twitchy. But I have not tested this myself. I hope this helps.

I don't have the drop down menu even with only 2NH coded. (werte was changed by me)



But I can tell that Cafds have no difference between 2NH and 2NH+SPBR, only the date of coding changes

Anyone do the 380mm rotor retrofit onto their car? I have the rotors on and my car came with 340 blue calipers (m240i) and S2NH option already.
