Power Class Change CAS Flash Error
Back again... this should be the last thing to fix on this car to get it running at full power. It's definitely in limp mode, it's SOOOO slow. It can't get out of its own way.
I realized that I need to change the power class on the DME (6BMOT) and CAS2. I was able to code the DME to wert_01 from wert_00, but when I try to code the CAS to klasse_01 from klasse_00, it doesn't let me write. I'm able to read it and modify the FSW_PSW.trc in NCS Dummy no problem, but when I try to flash it I get the following error in error.log Quote:

Just flashed the RSA delete as well as the Bimmerlabs stock tune file, and there is no difference. I still have 2FA4.

This forum is pretty dead I guess. So nobody has any idea how to fix this issue? I just need to delete the power class check in the tune.

The Bimmerlabs tunes pretty much do that but you need to pick the right files. |

If I match the tune to the power class on the CAS, it won't run properly since the modules are from a 325i.

Pretty sure Bimmerlabs has a 330 tune option for a 325. It will be the 330 tune with the Powerclass byte changed. Your project probably needs to use a VIN from a 325 and then the custom file option will show up. |

Well, it seems that did the trick! The car still feels a little sluggish/jerky to me taking off from a stop, but that may just be the automatic transmission. In the high end, the car feels great and the 2FA4 code is gone and has not returned.

How were you able to fix this?!?! I’m running the 328i msv80 with the stage3 manifold aa tune and bimmerlabs 330i tune on a 6spd manual before. I was not able to change the the power class to match on the cas and 6mbot to 2. Can you dm me or provide the steps to resolve this issue please!!! Thank you!

You won't be able to change your power class since there's a time limit on doing so. I'm not sure if it's the same for MSV80 though. Can you see the file on Bimmerlabs for your VIN? Also, do you have any codes or other issues due to the power class mismatch?

You don't need to change the power class!! Firstly it's not even *possible - it's locked on all DMEs that have it after 10 hours (MSV70, 80, MSD80, 81, etc).
The whole point of the 330i flash is it has the power class check disabled in the first place. If you did manage to change the power class on the CAS itself, the mismatch would still cause the 2FA4 error. * Technically, it can be done - by writing a custom program that forces the hours to 0, you can then code the DME. However, that would be fairly pointless - you still need an RSA delete for that, and you need an RSA delete to flash a custom file, which you want to do anyway - so just ignore the power class altogether and flash the custom file. |

Just for clarification on my last post, I was referring to the 330i tune being available for MSV80. Not if its power class can be changed.

Yeah, sorry - I wasn't responding to your post. But yes, there's a file for the 328i that works the same way. MSV80, MSD80, and MSD81 are all fundamentally based on MSV70 and work in the same basic ways.

Ah, that makes sense. I figured there had to be something for the newer cars.

Will the 2FA4 error code due to mismatch cause any less power with the 330i tune?

Yup, still shows up for me. Use a 325i VIN and you should be able to see an option for "MSV70_S7623406_325i_to_330i.0da".

No, you won't be able to use an MSV70 file on MSV80.

For anyone that has this issue, I fixed it through resetting the module 6bmot in ncs expert, reflashing RSA and tune and it worked fine after that.
