Need stock tune file 2012 lml E86 ecm

I need a stock tune for 2012 chevy lml here is all the info on my truck vin:1GC4KZC81CF173769, searial:1GC4KZC81CF173769, operating system:12644094. thanks in advance. from what i have gathered the lml ecm is a wright only.

That VIN and OS don't belong together. Your OS is going to be 12649244.
Although the LML ECM is write only, you can do a virtual read from the HPT servers. Just hook up to the truck with access to the internet, select read, and it will provide you with an OEM file for your truck.

On a side note, post up your stock read when you get it. You have a very unusual System segment, that I'm sure the Duramax community around here would love to take a look at.

yea I will but this is what I got from my vcm suit infio

I do not know if that was with my H&S still downloaded but ill double check in the morning.

If it was previously tuned, a scan probably won't return your OEM calibration information.
Many tuners love to use 4094 OS's on the 11-14, which that one is.

As mentioned, if you do a read on your ECM, the HPT server will get you the proper calibration for your truck.

I have tried reading the ecm multiple times and I keep getting a failed read and I also had internet and when I did try just reading the ecm alone also but same thing I also tried clicking on the internet link before read and it said (The action that you selected requires internet connection) but I was connected to my house Wi-Fi with strong signal.
