ECU Tuning & Fuel Management - 1990 Acura Integra ECU?? What is it?

I am looking for a rundown on ECU's. Does anyone know of any sites that has a referrence for hona/acura ecu's. Like for instance the Civic EX having a P28. That type of thing.

I do not know what ecu it is that i have either, as it is out of a Acura Integra. Please provide me with any information you possibly could.

You are my hero.
Thank you.
