W221 AMG Menu Pre-facelift Model

[waxxx]

I want to surprise my neighbor.
He has a good old pre-facelift W221 model that he tuned to make it look more aggressive/exhaust, etc.
Does anyone know the procedure/type of UDS commands to save the current configuration and activate the AMG menu in KI221?
Thanks to everyone who is ready to help.

I would say you need to manually unsolder the EEPROM and change the dump.
Reset the mileage using any method and perform the initial run, or compare the two resets using any method.

As far as i know, there must by "only" changed some bytes in the EEPROM without any unsoldering, but don't know the correct UDS commands to change them properly...
Only have some information about bytes to change and offset. Maybe the KI221 also needs to be upgraded, first...

For non-facelift W221 you will also need to flash the cluster with newer software. The W216 platform had an AMG version from non-facelift. The update can be done using offline programming DAS, Vediamo, Autel online, etc.
