OS 12613246, 2006 Silverado 5.3 4l60e, has alot of invalid PIDs..

I was trying to log a buddies truck this weekend with OS 12613246, we could not log GM.DYNCYLAOR_DMA, GMCYLAIR_DMA, and a bunch of the Idle PIDs (throttle cracker, throttle follower, etc)... Any reason for this?

Also everytime we flashed a new tune it it would go threw this wired cycle about 5mins into logging where it would command 16.0 and then 13.61.... I could not figure out why it was doing that.

Attached is the stock tune.

The DMA PID's may never have been defined for that OS. Looking back I suppose 2006 was a bad year with many V8's switching to the E40 or E38 ECM's.

interesting, well he is considering switching out the pedal and TAC assembly so he can load a 05 OS in his truck. anyone had experience with this?
