hey, my question which I need a lil clearin up about is: Are both o2 sensors needed in order me to avoid a check engine light? My other question is by my understanding, the primary o2 sensor is a wideband o2. When a wideband was explained to me, I was told that the wideband simply shows how the fuel is burning and to help tune the car. Now, where I really became confused is when i received my header from hasport and noticed that it only had one hole for an o2 unlike a dc sports tsx header which had two. I know that on the stock exhaust of the k motors, the o2's are place on teh cat converter which is the reason that I am lost....Some please clear this up for me...thanx

2 sensors are only needed if you plan on running a stock ECU (you will have a code if only one is connected). If you plan on upgrading to a Kpro ECU you can disable the secondary sensor and bypass running the wires for the secondary sensor.

how do you go about disabling obdII to run in an obdI car if your using a stock ecu? if you do this you dont have to use the secondary ecu, right?

like hybrid said to turn off the obd2 a kpro is needed OR sending the stock ecu to hondata( which you cannot personally do yourself hondata dealer only i think) and honstly if you spend the money on the kpro you will not be dissapointed!!!! that thing is the shhhh..!!!!
