Need to know if the d16y8 is OBDO or OBD2. The blown d16a1 I am replacin with the y8 is OBDO. What do I need to do to make it work if not the same? If this helps, the d16y8 had vtec and came out of a 2000 civic ex automatic and will be goin into my 1990 civic ex 5-speed. I'm not trying to hookup vtec now, just keeping computer til I have $ to get installed by local tuner shop. Please and THANK U for any valuable info!
