Wideband input on the 2011+

[Deespeed99]

How are the widebands for each bank reported back to the PCM for the 11-13's? Does each bank have it's own input back to the PCM? Also how is the signal or input from the O2 sensor reported back to the PCM? Analog like an AEM/Innovative setup (0-5v) or another way?

I'm curious to see if there is a way to use an AEM kit with a single turbo setup. In order to do that you would have to mount the O2 sensors before the turbo (which I already know is NOT recommended) but they sell a exhaust back pressure kit when sensors need to be mounted directly to each manifold or pre-turbo to compensate for the higher backpressure.

The goal is to have an aftermarket kit like AEM monitor A/F for each bank and report it back to the PCM so it could make adjustments like stock, TT or S/C setups allow and make tuning a little easier as well.

I have the Aeroforce Interceptor Scan gauges, and it reads the AFR directly from the PCM, and does read each bank separately, along with commanded AFR from each side. Not sure if this info is useful but that's all I can offer.

I don't understand why you would want to do something like that. Why wouldn't you just weld a bung in the exhaust and install the wideband normally? Sounds like the aeroforce gauge is what your looking for.

So you're using the stock O2 sensors ran directly to the gauge using the input signal from that pin on the PCM? Do you mind being more specific with the wiring? Or are you using the Aeroforce O2 sensor?

Because the stock PCM uses the signal for the left O2 for that bank and the right O2 sensor for the right bank and makes some adjustments based on that info (a tuner could chime for a better explanation). On a single turbo setup you're running both banks into one exhaust output so you now have both banks exiting the turbo into the down pipe so lets say something is running lean on the left bank but the A/F is still what the PCM is set for the potential for blowing a motor is higher because it assumes both sides are doing the same thing. You aren't supposed to run anything before the turbo because of the high back pressures which don't give true A/F readings...Make sense? If not that's because i'm horrible at explaining stuff :lol:

I dont have ANY special wiring. The cars have WIDEBANDS already, and the PCM reads it (IDK HOW). ALL the Aeroforce gauge is doing is displaying on my gauge what the PCM is reading. You need to ask a Ford specialist how the PCM is reading the AFR from the 2 sensors.

The Aeroforce plugs into the OBDII port. There is no special wiring.

I know what your talking about and what your trying to accomplish, but I don't understand how. Any 02 before a turbo isn't going to give correct readings so how do you plan on using an aftermarket wideband to correct this? The only way to get a true reading is to put the wideband after the turbo and that obviously won't read each bank.

AEM sells a kit that designed for sensors to go before the turbo that compensates for that.
