wow, 20 frikking pages! I really want to get into this but i don't think this will do what i want it to. So im going to throw this question out to those more knowledgeable than me here.
Vol firefighter, use my 2020 to respond to the firehouse for calls. In my 2016 i was able to purchase a device called a z-flash, which would plug into the OBD port. When i held the high beam stick down, it would flash headlights, brake lights, etc, looking like a pro light job. Said company doesn't have a compatible device for the 2020. Does anyone think this could be done with forscan? If not how did they accomplish this on the pre-2020s? I wont post the link but a simple google search should find it.
thanks in advance!
