I have no hole on my floor to get the wire to pass through, i also sont have a bung on my exhaust for the 2nd o2, and i also dont have a cat converter. A lot of machine work which is why i want to bypass it.
I will eventually add it but will have to bypass for the meantime.
I checked o2 1 and the resistance is just around 3 ohms. I used 12 ohms on my o2 2 heater. Could this be the reason?
