I just put my DSM 450s in the other day on my Integra for the exact same reason as you.
what I did is I just installed them "duh", and using a chipped p72 ecu I took a basemap loaded it on chrome, and used the injector size conversion tool and a few minor changes to the map and its working out great.

I am assuming you are using the DSM 450's? If so and im not sure with your engine, but with mine I had to use resistors to keep from frying the ECU

If you have any more questions let me know.
