Wideband Sensors

wheee!

What are the benefits from installing wideband sensors in my Berk HFC's and secondly, can this be done with the existing wiring harness so the info is fed to the ECU?

Thoughts?

IMO there's really no benefit unless your FI. There's really no need to run to the ECU for it already uses the the O2 sensor to moniter A/F. If that could even be done. Maybe with a stand alone ECU this could be had.

The 370z is already equipped with wideband primary oxygen sensors that's why they are so expensive. Buying aftermsrket ones would be a waste of money.

wheee!

whuuuuut...? The oxygen sensors are behind the cats. The wideband sensors go BEFORE the cats....

Uh, yeah. There are 4 O2 sensors: two primary sensors in the headers which sense the A/F ratio and play a major role in the way the car runs as the ECU uses that A/F information to adjust both cylinder banks fuel/timing to maintain an optimal A/F ratio. The two o2 sensors that are in the cats are only there to monitor the condition of the converters, basically to make sure they are present and doing their job.

To access the A/F ratio, you can use OBD 2 live monitors.

wheee!

So what is the purpose of the 2 extra bungs on my Berk HFC's???

I think people are misunderstanding your point. The extra bung is for additional widebands that you can ran in order to be displayed inside the car via a gauge which most run when there FI to moniter A/F under boost. Such as the company Innovate Motorsports.

No. Run whatever the ECU needs for the secondary O2's. Tune according to the factory wideband O2's for the front. Do not bother purchasing aftermarket O2's for either.

Awesome info everyone! Thanks!

The Berk HFCs also fit other cars which may not have wideband o2 sensors standard. You may not need the additional bung but it never hurts!

Independent Air/Fuel ratio gauge like Innovative ( 1 or 2 )
EGT sensor

That's what I use them for anyways

wheee!

I guess the HKS Camp II would display the A/F ratio from the factory wideband then too. On Nav enabled systems of course.

^Yup, you got it! The awesome thing about having two wideband sensors on each bank stock is that you can monitor each bank of cylinders independently if the display has that capability.
