Bought my first Wideband.., now what??? ((pics))) Options

[southwest2118]

picked this up today.







i'ma put it in and see how well it works

I dont know where to put the sensor though. need help guys

reading a lil i found this .... whats right and whats wrong?

The sensor can often physically replace the
existing oxygen sensor, but for proper operation
of the ECU, it is often desirable to provide
another bung for the wideband sensor. We
recommend you place the NTK sensor a little
downstream of the existing sensor, and certainly before the catalytic converter.

"Always mount the sensor 15 degrees or more
to the horizontal (in the 10 to the 2 o’clock position with wires at the top)."

Some tuning shops use an adaptor that holds the oxygen sensor, and this adaptor is then
secured to the end of the vehicle’s tailpipe. This position is not recommended for vehicles with a
catalytic converter as the converter will change the readings you are measuring (that’s the cat’s
main function in life!). For carby vehicles (or non-operational cats on EFI vehicles) this position
may also be a problem as the exhaust gasses can be quite cool after travelling the length of the
car, and the sensors heater may have to work too hard to maintain an operational temperature.
Serious tuning will require a hotter position closer to the manifold.

Vehicles with a turbocharger should position the sensor after the turbo (and before the cat) as
a high exhaust back pressure (as will be found between the manifold and the turbo) has an effect
on the measured AFR and tends to read richer than is actually the case.

i'm running the 7afe on a t3 pushing 10psi with safc and 315cc injectors.....ummm the yellow top supra...
for the past year i've been wingin it......now i get to find out how rich i've been running....also the thing about this wideband is its not the 1-5volt kind most people use..its 1-3v i guess its not too bad??






any advice other then get a new wideband will be appreciated ...

I have always seen what the first quote suggests. Right around the area of the stock O2 bung but before the cat.

you should mount it right around your existing 1st o2 sensor bung.
just go down to your local exhaust shop and say o2 sensor bung please
shouldn't cost more than $50 (if that) and then you can screw in the wideband and run the wires into the cabin

and yes you want to run a lambda of 1.00 ideally
