MGFI, question, running rich

I am considering doing a MPFI swap on my D15b2, but am hesitant because if I use a ecu, out of the Si (which I would have to), won't it think I have 1.6l, and would it run rich, or am I wrong with this?.....thanks for your help

Nah dude, it would run good.

I just did this and am having no problems, do it and you will love it.
