ok well i have 96 accord and like i was planning on doin an h23 full swap i bought a obd2a p14 before hand. But then i found h23 head rebuilt really really cheap so i bought it and ill just do the head swap. Now i was wondering if i can still use my p14? Also instead of chipping it for engine management can i run greddy e-manage or the ultimate one? of course getting it tune with it. its cuz like i wanna boost the motor later on, and trying to figure if i can still stay obd2a for i can pass emission with an ease.
