I will need to get an emissions test done soon. I currently have an obd1 b18c1 in my 1997(obd2) ls. I run a jumper harness and the obd1 ecu. I recently bought a obd2 p72, installed it, and everything seems to work just fine. I already have the extra o2 senser and and obd2 cat. Is there anything elce I need, such as injectors and dizzy, to pass emissions?

 

no one?

 

No ones knows the direct differences in obd1 and obd2?

 

crank angle sensor, i think you have everything else

Yeah, I think I do need that too. I had hooked up an obd2 p75 to my b18c1 and it only blew one code, 1337, which is the crank sensor code. Is it possible to install one of these on an obd1 motor? I will do some serious searching but some more specifics would be nice. btw I already have a obd2 p72 so a itr ecu would not be necessary for me.
