I am planning on getting one of these real soon now. I'm wondering, did most of you take out the factory o2 sensor and replace it with the greddy? Or did you weld on a new bung for the greddy sensor?
If you just stuck it in instead of the factory sensor, did it act funny before the break-in was complete? Do the threads match or do you need an adapter?

ur suppose to use a new bung

 

The Greddy gauge comes with it's own bung. I am still fighting with my install! If you want to use the Greddy sensor as your main you will need to download the wide band o2 install info from Hondata. A 1k ohm resistor needs to be wired across the OEM heater wire and heater ground wire and the Signal ground needs to be tapped into the Greddy ground.

o2 signal wire is white on the sensor but yellow/red on the harness side
o2 sig ground is green " " "
the two black wires are the heater wires.

I cut an extra plug from a junkend car but I didn't want to hack my sensor wires. The green wire from the greddy harness connects to the white wire on the hacked donor o2 harness.

I'll post a pic of my harness and the Hondata link later.

 

I had an extra bung welded on before the cat...didn't want to fool with the stock sensor...if you need the English instructions I have, send me an IM and I can direct you to where they are located.
