First time COS upgrade, lost.

[Cody@LoveFab]

Truck is an 03. Twin 62mm, 5.3, 4l60 trans. OS 12593058. By the Tutorial list, I should be Full Flashing COS 03190003.

My problem, is I cannot find the .tun COS 03190003 to open and flash into the PCM. I have to be missing something so obvious. I have found the .calz 03190003 in the "Custom" folder of LS1B, but I cannot open it, or find anywhere to "select" it to full flash into the PCM to complete the tutorial.

I have successfully tuned a TT G8 GXP so my EFI Live cherry was painfully popped with that car. Suggestions?

Under My Docments\EFILive\V7.5\Bins\Custom OS

[Cody@LoveFab]

Yep, Painfully obvious. I kept looking into C: drive, program files, EFILive. I'll update with results, thanks for the prompt response!!!!!!!!

[ScarabEpic22]

No prob, theres that place, the program files, program data, and then where I keep my tune files. Whew!

[Cody@LoveFab]

Couple that with the umpteen other systems I tune and have to keep track of, this becomes very difficult to navigate! :-)

[Cody@LoveFab]

Wanted to thank you for the help. 8 minutes later and I was tuning.

Thanks again guys!!!

Glad you're all set now!

Good deal thanks Erik.

Be sure to get rid of all the out range or limits that pop up when you open the tune, that will save a lot of headaches. If you run into anymore problems feel free to give me a call, I run custom OS all the time and can most likely help you over the phone.

Good point, make sure you fix all the OOR cells before you flash it.
