They both have multiple LED units for the normal headlights while the PreLCI has a Laser unit under the normal headlights.
I just need a G20 LCI with Matrix LED to compare the coding to my G21 PreLCI with Laser headlights.

Maybe JayPichardo can share the G20 LCI headlight specs aswell. |
They actually are completely different, as its a different technology. The preLCI is using a mechanical mechanism for the selective beam with only a few LEDs behind, the laser is only used in addition to the LED for the high beam to increase the range. Without high beam you just have LED on.
The matrix LED is more software controlled without any mechanics to avoid blinding oncoming traffic. It has much more led modules which can be turned of individually. Basically same system Mercedes and Audi is using for a while now.
So in short. They for sure will have different ECUs, as technically it's a complete different headlight unit.
