Is this the BCM?

Looking at this pic in the attachment, and the diagram below, would this be the BCM?
Im assuming the attachment is the BCM, thus not the part to send out to be "tuned"

The part to be tuned is the ECM (Engine Control Module).
I don't have a pic/diagram handy, but if you lift the hood, it's on the pass side of the engine bay, towards the windshield - two slides lock the lid down, open it up and there's a load of wires/connectors which require unplugging.

Figure 2 is the ecm(ecu). There a 4 connectors leading into it. You can remove the plastic sheath along with it, or leave it.

ACRucrazy, it looks like you have the right one for the BCM. I haven't pulled mine out but you have it right according to the diagram. I know the other two are the ECU and RCM.
