Would a stock OBD2A P72 run a B16A2 properly? Or would it cause it to rich?

I just purchased a Civic w/ a B16A2 swap but its got a OBD2A P72 and its running rich. Just trying to figure out whats the culprit.

 

A P72 will run rich. Remember that it is programmed to provide fuel for a 1.8 liter.

 

runs a little rich, I added nitrous to mine and it ran like a champ, I ran a 75 wet shot, ran pretty good....

 

Not to thread hijack, but if you need/want a P30 I have one up for grabs.
