What year is your car? Sorry if I missed it, but it's vital.
The OEM ECU works fine for 2006+ AP2 DBW car, you just need to access the computer. Hondata FlashPro for example. For others you need to know if you want to preserve the ability to pass smog testing. The '06 and later ECUs can be Honda FlashPro tuned simply by connecting to the OBD2 port and a PC. (Lots of knowledge required -- which I don't have -- but that's all the hardware needed.)
'04 and '05 AP2 cars and all AP1s in North America need a piggyback ECU if you want to pass smog and only a couple of them will pass smog. Or a complete stand-alone ECU -- which is unlikely to pass smog. Someone will know which if any stand-alones will do this but many (most? all?) lack a OBD2 port which is how most emissions testing is done.
If emissions testing is not required there are some very nice "plug-n-play" standalone ECUs. Haltech for example has one for the AP1 and early AP2 cars. Since this ECU just replaces the factory ECU it appears the OBD2 port on the car remains functional and the car may pass smog. ??
There's a reason all this aftermarket stuff is marked "For Off-Road Use Only."
Engine tuning has the ability to completely bugger the engine without lots of knowledge. Which I don't have so I had a Gernby tune applied to mine.

I live in Maryland and have already passed emissions, however, this happens every two years. They use the OBD test so as long as you don't have any CEL or outrageous upgrades, you'll pass. But I would need an ECU that allows for emission testing if possible.
