JRSC Fuel Enrichment Relay

It's here, it's here!! UPS dropped off two big boxes on my doorstep yesterday, I'm almost supercharged!!

I have one question, I'm obviously installing a JRSC on my 95 civic. The car already has larger injectors and a bullfrog computer programmed to run them. I have the JR timing control, new fuel pump and Cartech fuel pressure regulator I will be installing with the supercharger.

My question is the JR Fuel Enrichment relay, my understanding is that it "tricks" the computer into thinking the air is colder than it really is, thus increasing the duty cycle of the injectors. With the larger injectors, reprogrammed computer and Cartech FPR, do I need this thing? I don't really like the whole idea of how this thing works. When does it adjust the duty cycle, over the whole rpm range, at closed-loop part-throttle?

Thanks in Advance,
