Dynojet WideBand 2 install in the G8...

[DynojetResearch]

Here are the pics / notes from the Dynojet WB2 install. I chose to use the driver’s side downstream o2 bung for the location of the wide band sensor, and of course this required that I remove the OEM downstream o2 sensor. If you chose to do this, you’ll also need to reflash your ECM in order to avoid any trouble codes.

Here’s pic of the wide band sensor location.



Since the factory sensor is removed, you can use the same location to mount the wide band connector on the side of the transmission. There is an integrated “push dart” on the side of the connector, and you can simply push that into the hole on the side of the trans case.



I then ran the wide band sensor harness behind the factory heat shield, and the routed it through a hole in the frame rail.





After you fish the harness through the frame rail, you can then route it back through a hole to get it near the location where it will pass through the floor board. There is a small “knock out plate” in the floor board, and drilled a .25” hole into that plate. Note: before you drill a hole, make sure you pull the door sill panel off and pull up the carpet. There is also a large gauge power wire in that area as well, so I would advise moving that as well while you drill the hole.





You can then snake the harness under the carpet and over behind the kick panel on the driver’s side.



I then wired in the sensor wires from the harness into the Wide Band 2 control module (6 wires).

After I secured the Wide Band 2 control module to the metal rail / bracket, I was able to run the ground to a lug at the firewall, and then sourced key on power at the fuse box.







I’m still searching for a gauge pod at the moment, so until then I just using the 0-5v output from the WB2 to pipe data over to my HP Tuner’s MPVI Pro device. The AFR on the street is tracking exactly to what we were seeing on the dyno……….nice!
