With an all motor built engine it becomes a big plus with fuel/air mapping and you can see some definite increases with a programmed chip.
With a stock motor or one with simple bolt ons then it is very pointless really...kinda like putting an aftermarket ignition system on an otherwise stock car or even pne with a minor build on it.
Even with the work going in on my engine I am still running the factory ignition setup but a reprogrammed ECU.

As for the Honda ECU's that can be configured via the diagnostic connector. Any OBD-2b (RSX and other late model Honda's) and probably (all though I can't be certain) OBD-2 Honda ECU can be tuned without the need to "chip"
The reason people convert OBD-2 to OBD-1 is simple really. Cost. Cost drives everything. OBD-2 ECU's have there processor/micro controller and eeprom incorperated together and is quite expensive to pull and program. Each one of those chips cost about $200. When an OBD-1 eprom (TI27C256) can run you as little as $1 each and can be swaped all day long.
The OBD-2b and OBD-2 run an eeprom instead of eprom which means the eeprom is electronicly erasble which is how they can be programed via the service conector. Although already done the software/hardware to do this is extremely expensive now and in reality if you don't own a shop or are a large tuner that deals with this on a large basis it's just not worth the investment. So they just convert OBD-2 to OBD-1.
I prefer OBD-1 simply because I know more about it and I can program it but OBD-2 systems are pretty bad ass in how they can help technicans find and repair problems.

To the original poster, what mods do you have on your car???
If its not much, save the chip money and put it towards other bolt ons; you'll get much much more dollar for dollar. Id only consider a chip if you've already done everything and I mean everything else and still have money to burn.
Accords wont get the gains Turbo cars like A4's get in which a chip swap ups the boost for big gains.
