hey i have a 93 honda del sol SI. it had a D16Z6 in it already so when i decided to do this swap i kept the original wiring harness. I bought a JDM B16A2 which came with the computer and everything. I wired in a knock sensor and i had to extend various wires. The engine runs well but it is lacking power... the check engine light comes on and reads code 2 wich is oxygen content i think. I read that in this kind of swap you shouldnt use the P30 computer cause its tryin to read a second o2 sensor or soemthing like that? I read that you can use the P28 that came with my car if you buy a chip...if anyone could help me it would be greatly appreciated
