2009 CTS-V Communication Issues (Not Receiving Certain Data Fields)

So I know this is quite a long shot, but here we go. I recently got my car cammed. When I went to have the car tuned, my car was not showing data from the ecu in hp tuners. It was blank.

The Cylinder air mass, MAF airflow in Hz, injector pulse width, IAT2, knock retard not showing. It was showing tcu data. It?s like some communication error or something in the car. My tuner has a very high reputation and has never seen anything like this.

My buddy who is a GM technician then used his computer with all GM software and was able to pullup the data that is missing in HP tuners. I am not sure what this means fully as we are all puzzled. At this point I think its a bad ecm.

Also, the stabilitrak, brake assist, and traction control lights are all inactive as well as the airbag. I think whatever the issue will fix is, will fix that.

My question is, has anyone had an issue like this?

I have a 2009 CTS-V Sedan Auto.
