Why would the distance matter? Shouldn't the exhaust gas composition be the same regardless of the distance from the cat? I can't imagine that the gas temp would be an issue, either.XDGT03 said:measure the distance from the core of the oem cat to the center point of the o2 sensor on the stock set up. I think it is about 14.5 inches. When you put in the new system, make sure the distance from the new cat and the repositioned o2 sensor is exactly the same. this "should" prevent the cel. I
I talked with an exhaust guy who went to some training where they said moving the o2 sensor as little as 1/4 inch can cause a cel.Why would the distance matter?
Maybe as the gas cools, it changes in compsotion. (just talking out my ass on this one)Shouldn't the exhaust gas composition be the same regardless of the distance from the cat?
Ours are heated. However, too close to the cat may cause it to "overheat" and give false readings because of it, or the above statement.I can't imagine that the gas temp would be an issue, either.
I am a little confused by this maybe I am just reading it wrong. By sensor side are you referring to the actual o2 sensor that you can disconnect. When disconnected it is about 7-8 inches in length? If so that is what I cut, extended and soldered, on 3 cars now with no problems whatsoever. Maybe if you can post a pic or schematic from HMA.O_GT said:I spliced and soldered the the harness side and used bigger gauge wire as not to cause more resistance.Do NOT SPLICE the sensor side this will damage it.
I'll try and check todayXDGT03 said:evil, how far is you o2 from your cat?
