I installed my AEM a few months ago along with a boost gauge. The AEM uses its own dedicated wide-band O2 sensor. All of the material I've read suggests that the stock O2 sensors are narrow-band (only the GT3 part # for the Bosch sensor indicates a wideband O2 sensor). If that's the case, I'd trust the AEM over the Brockway every time...

he used the white face.. i used the black face... but you get both anyhow.... yu just unscrew the faceplate of it... YU get the O2 sensor in the kit and have the exhasut dude insytall it... or yu take out the 02 and do it yourself...

the sensor that comes withthe kit clicks in the the rest of the wiring harness....so that is why it makes an easy install...after that you only need positive and a ground..
so much easier than the boost controller install..... although...that in itself wasnt rocket science... just time consuming....

According to the Service Information Technical Introduction manual for the 996 Turbo, the pre-cat sensors (LSU4) are wide band. The sensors between the primary cats and the main cats (LSF4) are called offset sensors and the manual does not address their exact function nor does it mention if they are wide band or not.

Great find.
Looks like you have order from a dealer, who did you order it from? Also what accessories do I need to get boost display and shift light?

You can purchase it directly from Brockway Engineering. Here is the web site - http://www.brockwayengineering.com/r920.html
A couple of things to be aware of:
1) You have to request amber graphics or you will get green.
2) Connection is simple - it just plugs into the OBD2 port. The S100 shift light plugs into the R920 and takes the tach signal from it, but if you connect this way, you have to select "shift light" mode in order to use the shift light and you will lose the AFR function, as long as you have the shift light selected. The better way to do it and the way I did it - wire the S100 shift light directly to the tach wire just above the OBD2 port. This way you have AFR at all times, as well as, the shift light at all times.
I did not connect the boost display, so you will have to ask Eric (Brockway) about that. I think it requires a pressure line to be run to it and possibly another module...

I just got their email saying the R920 model have been discontinued. New models won't be available til next year.

Dixie-
How did you mount the gauge on the steering column? I'm looking to do something similar, if not exact. I'd like to have a boost gauge mounted up high near the instrument cluster.
Thanks in advance!

The steering wheel is from FVD but RAID has exatly the same.The FVD costs 1000$ and the RAID 600$ including airbags.At full throttle the readings from the AEM and the Brockway are almost the same .01-.02 difference somethime, but at idle the difference can be more ,I think it's because the AEM reacts very quickly and the Brockway is about 1 or 2 seconds slower..
