Please any answer are welcome

I've got the FR but not for free I haven't studied it yet so can't answer your question.  Nice getting a full read, thank you.

Do you want to switch off secondary lambdas for no cats?

Thanks to all
 Problem solved by my self.

good time

Do you want to share it?

Hello All

New question, sorry.

I have a customer and he likes to have a shooting sound by change the Gear. ( Like Popcorn )

Any one have a solution?

Any thoughts on the question that was asked of you? Or is this a one way relationship?

+1

There are many ways of doing it.  Diagnosis needs lots of conditions to be fulfilled, so changing any one will disable the diagnosis.  Eg min or mac EGT to enable diag.

I am fully aware of how it's done. Just trying to make a point to the OP I guess.

Hi,
I really don't have any Idea how to doo.
If somebody have time for a sample file, that will be great.

BTW attached the O2 off File
Testet and it works to 100%

I don't see any O2 sensor diagnostics being turned off in your file.

Yes then sorry for you, but file is working to 100%

let's hope this thread get's better lol

o2 sensors no, but you're being pedantic. You know that 90 percent of people that want "Lambda off" are asking for cat removal, and that's exactly what this file did.

MAF threshold for catalyst diagnosis (minimum) ip_maf_min_cat was changed to higher than possible values.
MAF threshold for catalyst diagnosis (maximum) ip_maf_max_cat was changed to lower than possible values.

In effect, the conditions to diagnose the catalyst will never be met.

41E9C and 41E9D lc_ls_down_obd_2_man_deac should disable all OBD diagnosis of the rear sensors as well if needed.

This is not how I'd have done this, but it works.

I know too well that I'm being pedantic, however, people should learn to state WHAT they actually want, jeeeeez

It would be nice if people would post their methods after using the forum too

I chalk it up to the language barrier.


The thinking is "why give away what I can sell?"

Good to see some answers at least then.   

I must say the stupid var and map names annoy me in Simos.   

They are nearly retard proof. It's almost too simple once you forget about the clusterfuck that is bosch.

Lol I'll keep that in mind,  they just seem too long.

I must have spent too much time in IDA with ME7 :)

Agree i hope it too  :)

That full read is actually encrypted in places buddy.  Virtual read was it?

Answering my question would have helped buddy ;)

This isn't a read at all.

It looks to be what CMD call a virtual read, where they decrypt the FRF and obfuscate the code areas (containing their code changes) and leave the calibration area open for editing.

That's what I said a few posts back lol

Thank you very much ddillenger  :)
 
That was a helpful information.

That is the way how a forum have to go on.

Thx again and have a great day

Roi

Share yours next ...... ;
