I want to do away with my 2nd o2 sensor, and i want to do an obd2 - obd1 swap. Which obd1 computer would be compatible with my 98 dx sohc non-vtec? Besides the obd2 - obd1 jumper & obd1 computer, is there anything else i need to do the swap? What would be the best computer.........P28.....P30....etc? My stock dx exhaust manifold cracked and was leaking exhaust fumes.....so i bought a header but it only had one o2 bung in it! So now the 2nd o2 is throwing codes. Ive heard that an obd1 swap is the best remedy for the 2nd o2 sensor......and also for better performance.
