Title: Passat B5 AWT ECU on B6 BEX
Post by: BlackT on May 20, 2019, 10:28:22 AM
How hard is and how many maps I need to copy from BEX to AWT ecu.
The idea is to make a spare ECU for my 1.8T BEX
Edit:
Sorry for opening this topic in tuning, I thougt I was opening in noob. Can you plese move it to noob section

So transfer all the firmware and do it noimmo. What hinders?

BEX is way newer motor. It runs higher version ESP / ABS and probably other adjustments too.

to know what ecu he wants to use. AWM also had later versions.

Thank you very much for idea ;D . I did it and it works
I put BEX fimeware in AWT ecu. Do coding and everthing works perfect

yes no problem bro!)m.e. 7.5 hardware structure is the same, depending on the environmental class, so the program can be changed in size within a reasonable one.

Almost everything, cruise control doesen't work
Edit: cruise works too  ;D
I forget to do this coding

Why not just using the BEX Ecu? Are the pins different to the AWT Ecu? What coding is necessary to run the engine properly?

There's 32mhz and 40mhz ME7.5 ecu's.
And both of those could be found on B6 depending on year.

Transferring between 32 mhz is no problem, but if you put the 40mhz software into a 32mhz ecu it will obviously not work, and the board is different too.

Interesting! How can I see it what frequency the ECU is running? Why it's not possible to use the BEX ECU directly when the frequency is same for example? The ECU here looks same (only maybe a little bit darker mainboard).

With the me7check
They had the different bootrom versions

Maybe one of his ecu's was damaged and he wanted to use other as replacement?
The 32mhz parts are identical, only sw is different.

Read first post, second row ::)
Also there was not any sight I ever say that is not possible to use BEX ECU.

Ok, so I have a project where the ECU was swapped (BEX ecu to BEX engine) and the car runs like complete crap. If the stock AWT ecu is used then it runs much better (still not good enaugh because the tuning does not much). That why I'm asking. Maybe the BEX ecu is only defect. So should I also just flash the BEX software to the AWT ecu and do some coding or what is a good solution for that?

AWT ecus up to part number 018DF are 32mhz, 018DG onwards are 40mhz and are crossflashable with B6 BFB/BEX ecus.  ::)

Nice info.
I made printscreen of  3 files, H and J are crossflashable to my ecu, but with BP car doest event start. Bootroom versions same, but EPK different.
But me7ckeck doesnt show 32 or 40mhz, how to know which version exactly?

Theyre all crossflashable as far as the ANY other transverse wideband software
Only issue with the immo possible here

ANY of 1,8t, or wideband at all? For example, can i take golf mk4 2,0 85 N/A ecu (with wideband), and write 1,8T file?

How is it possible to fix the immo problem? I would guess that just disable it in the eeprom will not work. Maybe an eeprom copy of the root ecu and disable it help?
