I don’t think a Haltech ECU would pass inspection in most US states. I’ve had trouble getting my golf inspected with just a cat and a flash tune. There are emissions readiness monitors in most stock ECUs that need to show up for it to pass. The exhaust and tune i have aren’t even sold anymore because of the increasing number of legal restrictions. I get why it has to be that way but it does suck for people who want to work on their car.
I think it’d be more for obfuscation than completely hiding it. As long as there are other hidden networks on the ship you just name it something generic that blends in. I mean this whole thing is a really stupid idea, but naming it something like “COM.NAB_ISO:4133” would draw less attention.
