Need a Stock Tune for OS 15196784

[hheppner]

Does anyone have a stock tune or hot tune for a 2005 LLY with OPERATING SYSTEM VERSION = 15196784 and TRANSMISSION VERSION = 15196778? My truck is a manual trans. Also, I am looking to disable EGR as well.

That looks like an early OS.

Any particular reason you need that specific one?

I tried searching 05 stock files I found, and couldnt find that OS.

Thanks for your help. I will let you know how it turns out.

No, I thought you needed the same OS the ECM has. If I could or can, how would one upgrade the OS on the ECM? Is it just by whatever tune file you have or what?

You can changes OS by full flashing the ECU or TCM with a tune with a different OS. EFILive really makes it easy for us in that regard.

Just be sure to read and heed the warnings about the full flash. A cal flash is almost impossible to brick an ECU, but a full flash gone wrong can.
