My car is now a obd2 but i am putting an lsvtec into it with a p30 and ob2-obd1 converter so techenically it going to be a obd1. My question is do i need two o2 sensors or one??
My car is a 98 civic dx and i am using the jdm type-r header and carsound cat and need to know if i need to put a o2 sensor into my cat?
Thanks

 

Nope, don't need one in your cat.
