ok anyone here is something that i can almost bet will baffle you. i blew a piston ring on my non vtec h23 94 prelude si. so i decided while im buying a new engine why the hell not put a h22a in it. well i did and when i got it back it had some serious timing problem it seemed. i had srd (superior racing development) do the wiring harness for me because it was cheaper than buying a new one. it would sound like a gocart in low rpms if i stepped on it and it would jerk and hesitate after 3000 rpm, also it would put a check engine light on after high revs that would read o2 sensor but i bought new o2's and it still ran bad. i put the old ecu in and it ran fine. i figured fried ecu...swapped it and it did the same damn problem. idk what to say i thought for sure it would be that because the only difference between the 2 is a little more fuel and vtec. what are possibilities please
