Default JB4 and 2019 FACELIFT - 06-10-2021, 11:50 PM

HI, greetings from Poland !
Just replacing my RaceChip GTS with JB4 in 2019 C43 (facelifted) which should arrive shortly.

Just wondering, if I should use 2020 firmware (since CANBUS system in FL model is completely different than in previous models) or should I stay with the regular FW ?

I'd just install it and do a log, then we'll evaluate.
