Ok, right now i fab a downpipe on the compressor side of my 95 civic. The t3 turbo exhaust side is on that side and i put the o2 bung up kinda high near the exhaust flange. The thing was that the 02 sensor wasn't lnog enough and i had to lengthen the wires. My friend told me that if you do that, the signal may be weak. Is there any way i can "manage" the 02 sensor and keep the check light from coming on? I had to lenghtn the wires. I heard of maybe a 02 controller. Any help please.

 

any one?

 

why dont you just put the o2 sensor where it is supposed to go, in the stock location.
that makes more sense, and you wont be exposing the sensor to as much heat

 

there is no stock location on a custom downpipe. I wanted to put it closer but there are other things in the way. What about an o2 controller would that do me any good?

 

what did you do, extend the wires fourty feet?

come on, an extra foot isn't going to produce that much resistance in the wiring or be subject to any more inductance than stock wiring.

 

so i might be ok, gotcha.
