he wants to keep it OBD2 and the only thing out there is AEM EMS but it is way way more complicated. honestly go to OBD1 and hondata. the hondata will really tell you most anything you want to know because it uses the factory ECU but gives you the ability to turn certain stuff off like the secondary O2 if you are runnin a test pipe and don't want the check engine on.

edit-ohhh and if you want those injectors let me know they are just sittin here and have no use for them so make me an offer
