ECIS is awesome, was my first mod on my e36m3 and my first on my 330. Get one, it's so great for the money. Also, Sean and Kenny, the guys who run it, are totally cool and will help. They offered to put it in my m3 but it was so easy I did it myself. I was near Kenny's house for my 330 and was picking it up there, so he installed it for me for free (takes them like 2 seconds). A first class operation.:thumbup:
