    i just bought this 95 civic dx with a d15b vtec motor, its running ona p72 ecu and throwing a code 23 for the knock sensor which it does not have,

    my question is, is it retarded the timing because it has no knock sensor?

    also im have a code 1, and 22 as well.

    so im geussing the gsr ecu si overfueling and killing my o2 sensor---<correct?

    so my game plan is to find a p28 ecu and chip it with po8 maps and then replace the o2 sensor,

    also would like to know a reputable place to get a chip burned and ecu socketed

    I would just look for a P08, though you can run a p28 stock just fine. There r a couple good burners around. There r a few members on here that do them, I personaly have had good luck with Madfablab and Neptune
