I can suggest getting the cold start coded off altogether even after the issue is addressed. I know several NA and FI guys that have had their cold starts coded off. Especially with having an exhaust the car is much "friendlier" for those early morning or late night wake up the neighbors starts. I have always hated the cold start program from my NA hardly modded '08 to this car. It would make the car unnecessarily "choppy" too while it warmed up on both M3s I had. I'll be at ACM Thursday afternoon so maybe I'll see you around if you're there!
Thanks for all your input! I appreciate it. I already had the cold start tune before I went FI. I loved how quiet the car is on cold starts. The most weird part is usually when the engine malfunction comes on the cars idles rough. In this case the car is absolutely fine just on that first initial start up it happens.
