reflash c63 Ecu
I was wondering, how does the tuners reflash the c63 ecu? do they open it up or reflash it through the wireing harness? Does the ecu really needs to be taken apart in order to reflash it? Or it might not be?
and also, is it noticeble from the dealer if someone opens up the ecu to reflash it?
