OS number

[Philtopgun]

Ive notice some peopele with OS #s in their signature. When reg'n for efi it asked for my vin and then the next line asked for OS #. Im not loacting that number anywhere... I also notice a sticky stating how to find your calibration #, is this the same thing or am I way off?

nevermind, I think I got it. I read a tutorial on efi. Guess when I scan mine, I can convert it to their os#.

there is no reason to change os numbers and it is not recomended. you can do it though. you have to copy the os number then save the tune and then do a full reflash of the ecm

Thx. Didn't want to change it. It asked for the number n I didn't put 1 in, because I didn't know where to find it. On the tutorial it takes about scanning, then changin it to the #s listed.
I ain't changin nutin, this damn thing over my head. I'm just a plug n play. Leave the changin stuff to the peeps who desire to do so. My hat off to them!

Once you d/l your stock tune and open the file it will tell you your OS#
