Narrowband Air/Fuel Ratio Gauge

[angusmcraptor]

Looking for advice in installing a Narrowband Air/Fuel ratio gauge in a Gen2. Need to know stuff like where is the Air/Fuel Ratio Oxygen sensor etc...? Starting from ground zero here.

Narrow band? Most use wide band to monitor A/F ratios.

Was looking into that. Not sure if ability to modify the mix would void the warranty. But I'm considering it too.

A narrowband A/F ratio gauge is only good for a light show. Is this for looks or for tuning purposes? No real aka reputable tuner ever uses a narrowband O2 sensor for tuning. The 02 sensors will be located before the cats and after the cats. The ones that are used for tuning/engine control are the primary ones. Sometimes called upstream O2s. The ones before the cat.

Gen 1 Raptor has stock o2 sensors that are wideband from the factory. I would imagine the gen 2 to have them as well. All you need is a monitor like a scan gauge that plugs in to your obd port. Pick afr left and right bank out of all the parameters. I used my SCT X4 to monitor my afr when my truck was boosted.

OK... I'm talked into wide band. Sounds like climbing under the truck instead of digging around under the hood. Looking for a 52mm gauge. Any suggestions?

I responded to this on the other forum too. We have wideband O2 sensors stock. There is also a readout on the dash that you can monitor for AFR's. If you wanted a separate gauge, it would probably be easy. Just be careful because the that sensor is extremely important.

Thanks again. Now I’m rethinking. Might just need to invest in a good tune.

Here is a standalone unit, I've had one for years

The Aeroforce Interceptor gauge will read the A/F ratio and plugs into the OBD II port.
