Tach not working after Bootmod3 flash
So I just did my first flash on my 2016 M3 ZCP. I only changed some minor things like cold start, exhaust valves open only on S & S+, disabled active sound, GTS DCT, reset adaptations. Everything appears like it worked but my tachometer is pinned at 8.5k and won't move. It jumps up at startup, but never goes back down. Has anyone had this happen?
