Thermal Management Mercedes w212 E250 CGI

Hello all,

car recently received an official firmware update at the dealership, and the software version changed. My tuner is now unable to locate the maps on this new version because the map addresses (offsets) have shifted compared to the old file.
Here are the exact identification details of the ECU:
* ECU: Continental SIM271DE 2.0
* Hardware ID (HW): A 212 901 54 01
* Software ID (SW): A 271 902 44 09
* Calibration ID: 00344688409000AY
Our main goal is to improve the thermal management of the engine. We want to lower the operating temperature to around 90°C–95°C by modifying the map-controlled thermostat and the radiator fan duty cycle.
Does anyone have a matching Damos, A2L, or Super Map Pack for this specific software version (A2719024409)? Alternatively, does anyone happen to know the exact hex addresses or structures for the electronic thermostat and cooling fan control maps in this firmware?
