Well, the problem is trying to rule out specific things 'easily' without taking your truck out of action.
As I mentioned in my earlier post TechII was corrupting ECM's a year or so back that resulted in a similar situation to yours.
Do you know anyone else with EFILive (or a TechII in your area?)
Do you have access to another truck to just read it out to confirm your setup is ok?
Cheers,

No I dont know anyone with another duramax or efilive. I did read my tcm fine though so I assume that my laptop setup should be okay
Is Onstar fuse in? Just because you don't "have it" doesn't mean it isn't there, a friend of mine ran into that one recently, OnStar was OEM install (note, this is GM's desire) but no antenna or mirror present with OnStar.
After numerous reflash and no dice, he pulled the OnStar fuse which was there and it flashed fine.
Not sure if it helps, but can't hurt to check!
took it out and still did it. i am going to try again right now
before i try, say the ecm is corrupted, is there someway to fix it or will i have to get a new one?
Unfortunately there is no 'easy' way to fix them in that state. We've had a couple of users in this situation after a dealer update with TechII.
What might confirm if the ECM is bad, in the Tuning tool, there is an icon that looks like a chip (next to the read/flash icons), press that and see if the data the ECM sends back looks normal, meaning, is the VIN ok?, are the various part numbers shown ok? In particular, the Serial Number, Hardware Number, BCC. If you can please let us know what they are that will give me an indication of the state of the ECM.

everything is shown except for the bcc and hardware. the bcc box is blank and the hardware shows an n/a
it shows vin:1GCHK23194F152004 serial:3294000C219Z hardware: n/a os:15189044 calibration id: 15189043 bcc: blank
I'm afraid to say that at some point your ECM has been corrupted by TechII.
The telltale signs are No BCC, No Hardware#.
I might try to set up an ECM here and get TIS to corrupt it to see what we might be able to come up with.
