I don't understand the question - what firmware? I presume you changed the VO somewhere, and then updated the other modules in NCSExpert? You just need to undo that, you don't have to change any firmware.

[roflmao]

Another forum (now i thinking they are wrong) told, that there is a diffent with 525 and 530 dme flash file (firmware). Is it true?

that could be your problem. It's not necessary to change anything on the car. The DME has no idea that the tune is from a 530i - that's why we change the power class byte to match the car, instead of the other way around.

That byte is the only thing the DME is looking at, so it's possible changing the model number is now making it fault because now the car doesn't match the DME.

again, the only necessary change for using a 530i/330i file (higher power class) on 525/325i car is the power class byte. Nothing else needs to be changed.

Be sure he keeps the same vehicle code and country code as his original. Those are written into the calibration file and checked.

[hassmaschine]

yes that is true. But if he's using a file from an EU 530i to start from, that should work fine without other changes.

So just for the record, it would appear the CAN power-class byte is sent from the CAS module and it seems that can be freely set with NCS Expert. And as mentioned above, there are two layers of verification for the BN2000 cars.

First one is the check with what the CAS module. Second one is with a value that's stored in the NVRAM, which the DME only allows to be set if the run time is 0. So since we can't change that value easily, it's easiest to modify the tune and leave the CAS to what it was stock.

[roflmao]

So, what is this file? Can you please give the number of this firmware (ZB number) to input it in winkfp? Because if i undo changes with ista P, i will have a file from 525 without disa. Right now Zb number is 7623397, it is from 530 (i can see and use disas). Should i undo my changes and flash this ZB number in DME? Or i need another?

[Terraphantm]

Read the 530 tune, change that 02 to a 00, flash it back. Nothing else.

[roflmao]

Ok, thank you. Only one question, can i now read my own tune file, than undo all changes to ne53, flash this tune file. Will it be right and will i have working disas on all stok with flashed tune file from 530?

[hassmaschine]

I don't think you need to that.

1) you already flashed the 530i file with the power class set to 00.
2) you stated you changed your CAS from wert_00 to wert_02. Change your CAS back to wert_00.

That should be all you need to do at this point.

[tlow98]

I probably missed it in here, but I'm guessing you saw the revlimited thread where they were able to delete EWS on the MSSV70?

Likely you've got it, but just thought I'd cross pollinate.

[hassmaschine]

yes, I have seen it, that is me.

Thanks for the hard work :-)

So, if i understand this correctly (im not an englisch native speaker):
to Tune my EU-spec 125i to the factory 130i powerlevel, i need to:

- pull the bin (with kess v2 over OBD from my car?)
- use a hex editor to change the powerclass
- upload the bin
- profit?

[hassmaschine]

Well, it's not the power class byte that controls the power - it's more like a "checksum" that verifies that the tune file you have matches your car (to stop you from changing your 125i to a 130i).

What you need is to flash your car with the file from the 130i - with the one change to the file being you need the power class to match your car.

Here are the power classes I'm aware of:
125i/325i/525i: 00
128i/328i/528i: 01
130i/330i/530i: 02
135i/335i/535i: 03 (need to confirm)

So if you have a 125i and want to use a file from a 130i, you need the power class to be set to 00 in the tune so that the car will not be in limp mode.

[Terraphantm]

N54 is 02. 03 is apparently "prototype"

[hassmaschine]

Interesting, cool.

Took me forever to find the 328i was 01, made it really hard to find it..

NCS Dummy can tell you if look at the valid order options for the various parameters listed under "CLASS_PWR".

03 is apparently for prototypes and electric motors.

You know what, I correct myself. Seems like E6x and E9x treat some things differently (N54 is 01 for E9x, 02 for E6x)

Thanks for the reply.

But as i know, the 130i uses a MSV70 and the 125i the MSV80.
Is it possible to use the BIN from a MSV70 to flash into a MSV80?

BTW: Is there an alternative software for kess v2 to dump the bin file?

Seems like some N52B25s got power class 00, some got power class 02. So read your CAS module and check out what your "CLASS_PWR" is set to. If it's already wert_02, you should be good to go to just flash the N52b30 software.

If not, then it'll become a little more complicated.

[roflmao]

Hello huys! Thanks to all for help, i sucessfully converted my 525 to 530. I have one question now, my friend asks me to help him with converting 2005 e60 523 to 525. Is it the same procedure? Is the byte locates at same adress? Thanks in advance.

no, you cannot use an MSV70 tune on an MSV80.

There is actually an MSV80 130i tune though. It would be similar, but the addresses are way different on MSV80.

On MSV80, you can only read/write with the OBD port. So any OBD flash tool that supports MSV80 should work.

i can provide you a dump from e60 530 msv80 if needed.
