Any thoughts? hassmaschine

Fixed it, here's what i did:

updated the daten files in Coding tool,
Synced with WINKFP
Reflashed the RSA delete
Reflashed the 330i tune

Car runs now. Still has errors for 2FA4 but it runs again. I was doing some research on this error but haven't found anything without complicated steps.

I think it might have something to do with my power class not matching.

The only thing you needed to do was flash the RSA delete then the 330i file.

the 2FA4 is probably a shadow code from when you flashed a random stock file, because the program versions didn't match. if you clear it it should not come back.

I just cleared the EM and IM through INPA and they come back immediately. Am I missing something?

I found the url below but honestly I don't understand how to do all the steps. I am not familiar at all with NCSEXPERT.

Your better off to get Ista D going for diagnostics.
Because it's all in English
It has guided troubleshooting.
It has all the diagrams , specs for everything.

It's good you got Inpa going .
Have you searched on the web for an interpretation of the codes on
the web.

Also the questions about tunes for NA are better answered on the motor sub forum for NA engines.

Thanks for the info I'll get ISTA P after work today. I did do a lot of research as well as use google translate on the 2FA4 code on INPA.
After doing some research I think that it is a power class mismatch between the CAS and DME. The fix for it looks like it requires me to reset the hours in the ECU and then match the power classes in the modules and reflash.

Here is what I found- https://www.e90post.com/forums/showthread.php?t=1664944

The above link looks like this would fix my problem but I don't fully understand how to change that data yet. I can't find a detailed tutorial online and I don't know enough about NCSEXPERT yet to do it.

Although I did see that bottom link in your reply, it doesn't tell me how to fix it. It only tells me who to pay in order to get it fixed. I'm really trying to do all the work myself as it is a fun and learning experience.

Would you prefer me to let this thread die and make a new one in the NA motor sub?

Did you or somebody else attempt to change your power class?

No, I flashed the file from Bimmerlabs after putting my VIN in. I even reflashed the RSA delete and the tune again and same codes. I followed the steps exactly and WINKFP has the proper config settings too.

Not sure what the issue is. All drivers are up to date too.

Ista P is dangerous.
You should have and Icom cable and a regulated supply to use
is safely .
Ista D for diagnostics only is recommended .
The problems you mentioned come up a lot during the 3 stage upgrade
from stock files and in particular the bimmerlabs tune.

I have the K+DCAN and I have a battery charger that I can set to 50A if necessary. Will that cable work?

[ctuna]

Not advised I meant what I said.

Ista D is the diagnostic version of ista

Ista P is for programming only and you can mess up the whole car using it.

These are two separate programs.

Gotcha, well if I brick it then so be it. eBay will sell me another DME. I would like to try to fix this issue and I can't drive it around in limp mode forever. Do you have any steps I can try to get rid of the 2FA4/limp mode?

[ctuna]

I have never done tunes so no but there are multiple threads with the
error's you mentioned . Some people just gave up and got someone to
do a remote tune on it. that would probably be the best thing to do at this point.
I have done coding though . And you want to really read a lot of threads
on this before messing with anything.

From the above link

On my 2007 328xi I installed a 3 stage intake manifold from a 330i. I used the bimmerlabs code to enable the ECU to utilize the 3IM. I can supply the link to that if needed. I followed their instructions, and the code was successful. The car starts, but it's like it's in limp mode. It does a little better than limp mode but not much. There's very little acceleration. The programming status was ok after both flashes. It has two fault codes: 2FA3(code missing) and 2FA4(wrong data set). Adrian from SF********* fixed it remotely for a very reasonable price. He used the same code from bimmerlabs as I did, but he had to do some additional coding to change some parameters back to original settings I think he said so that the car ran normally. It runs great now with no fault codes. I'm very happy with it. He used NCS-Expert to make the tweaks. My question is how did he do that? I have watched NCS-Expert tutorials and read them, but I don't see what changes he made to make my car run so good after the 3IM upgrade coding. Can anybody shed some light or point me in the right direction? Thanks

If you do some internet searches on 2FA4 quite a few threads come up .
Something about changing the Powerclass in the CAS but as to why they never really
answer.

S F B M W coding is the place mentioned in the link.

Ok thanks for the input. I'll do some more research and see what I can find out.

Hopefully someone else will see this thread and chime in.

I would talk to these guys before you dig a deeper hole.

I would really like to figure this one out. I'm not giving up yet but i will keep that in mind.

[ctuna]

You might try making copy's of your CAS and DME and
doing text search for Powerclass in each of the files.

You use NCS expert to read the files out the same way you do for
coding.

I'll google that and possibly try that when I get home. Yesterday I was able to view that data using NCSExpert if I remember correctly but I have not tried to change any values of anything.

I also contacted SFBMW and they said it is $200 to remote code and remove the error. I don't think I'll be going this route but wanted to include this info for anyone reading this in the future.

that doesn't apply here. the 330i flash ignores the power class entirely. re-flashing the RSA delete is going to do nothing as well, that only disables the signature check.

The reasons I could think of that you're getting that error is you or somebody tried to manually change the power class in the CAS (so now it doesn't match the value stored in the DME), or the flash file was the wrong one and doesn't have the power class disabled in the first place.

I definitely never changed the power class. I don't know the software good enough to be able to do that or I would just change it back.

Maybe the flash file was wrong but I just put in my VIN and selected my ECU and the website gave me the flash file. I wish I knew how to read the flash file and check if it is disabled or not.
