The idea of a community around owning a certain vehicle is stupid imo. It’s the off roaring community. Or should be at least. Anyone who’d want to be associated with me because of what I drive sounds like a dumbass.
Flashing old software sounds like a great way to brick the PSCM or cause physical damage. It was updated for a reason, probably has some critical differences. Configuration is one thing, firmware is a very different beast.
