i have a 91 b18a1 that i (semi recently) swapped into my 88 crx si. i used the stock harness, lengthened where needed. i have a chipped pr4 running the stock program (turboedit). ive been running with no o2 sensor for a while with the hole plugged up with a bung. i had the o2 shut off on the program since doing the swap. my question is that harness for my crx is a 2 wire. the correct one for the integra is a one wire. is it possible to run a 4 wire o2 like in the obd1 tegs without actually going obd1? im trying to get myself situated to boost but i plan on getting a wideband kit first. ive been told that the 4 wire o2s are much better for tuning. any help on a solution or harness/ecu pinout alterations would be greatly apprectiated. thanks.
