Secondary 02 Sensor
 

1996 Civic EX 2 door. Is there a way to install a chip so the car thinks the o2 sensor behind the cat is good?

So i know i need the universal. But wich one do i need for the sensor behind the cat? The single input? Thanks for the link, good info!

yeah man thats the secondary sensor, which reads the cat's efficiency. Those simulators wont work for oyur primary one, which i beleive reads your a/f ratio only. And yes you need the single input, and if you decide to cut all 4 wire, you'll need the heater wire simulator too (not hard to install). I got mine off ebay for like $26, but that webstie (and a few other ones, i think maybe www.universalo2simulator.com or something) works too.
