Default Re: Engine starts up in "cold start" mode 90% of the time

My s54 swapped m3 does the exact same thing. I've been trying to figure out what is the cause of this cold start mode even when the engine is warmed up. My car is TTFS tuned with no CEL. It's driving me nuts. This can't be a normal thing, no way. Anyone has any suggestions ?
