I recently purchased my first modified Honda, it's a 89 civic DX hatch with a d16z6 swap. I paid $ 700.00 for it. I know the z6 uses a p28 ecu, so I was looking around and noticed it has a P07 ecu from a 92-95 civic vx D15z1 vtec. Also I realized I am also running a 1 wire 02 sensor. I was wondering what I need to do to convert from 1wire to 4 irew 02 sensor. Also can I just swap a p28 in with out any problems . Any help would be realy appreciated as I am very new too the Honda scene!
