because i have a friend which is working @ audi prototype engineering, and they work with Diagra ect too.

on a free saturday he came to me with his system and VAG Diagra license, he was able to log our cars with the provided odx.

So it cant be 100% correct what you guys telling. Also RAC told me VAG OEM versions, got other licenses, there is no need to get a security access on bosch, or specified patches,  seedkey .dll files for simos types to get in.

Also RAC did support Simos A2L filetyp in DIAGRA X first this year, after we and some others complained about the not standart a2l format. There was a update released this spring, after analyzing our logs from testing the last few month.

Probably log in mode 22, not in mode 23.
Mode 23 rejects access if ECU is not dev - maybe there is some secret handshake involved which allows it to pass, but I need to patch ECU, else it simply says the request is invalid. Mode 22 you can log with VCDS too.

This is something I've also been very interested in. I'm sure if someone created a proper logging tool for the Mk7 (high speed and logs the variables needed for tuning) they would sell plenty. But it seems from what prj said there's more to it. I'd love to be able to log the variables in the axes to the wastegate maps, and the turbo modelling variables, all which Cobb can do.

It would be interesting to see if Diagra actaully logged over CCP or is it just using readDataByIdentifier in a tight loop.  Also couldn't Cobb add some variables to the identifier table to log some extra variables?

readDataByIdentifier is 22.

Diagra does 23.

Hello,

Is there a way to rise diagnostic limit for MAF?

Is it possible? Yes.

For you? No.

Thanks for your answer, why not? Is it that hard?

Because if you had a tool that is capable of loading custom ODX you probably would not need to do this.
If you have mode 23 you just log the extended range MAF.

Best you can do using VCDS (because the scaling is inside the encrypted CLB file, and you can't change it), is to modify the memory location of the Mode 22 ID to the extended one and then you will have MAF value 2x smaller than it should be...

Really, if your question is "is it possible" - then you are so far from this that my explanations probably make zero sense in the first place.

Thanks, my english isnt the best, so maybe i wrote not correct. I know possible is more or less everything.
I have an old diagra-d. Rhere is an odx import option, so the bigger problem is i dont have any experiance with odx files and i dont have the file.
Maybe you can help me out and i can test how it works.

I helped you already by saying everything that needs to be done.
If you don't have good knowledge of ECU comms layer and reverse engineering, you will not accomplish this.

Service $23 is present and can be invoked same as all the other UDS services.

But it always replies back with ‘Error – Conditions not correct’

The workaround is to jump over the condition checks at the start of the routine. This means patching the ASM to jump over these checks.
