You have to find a 12212156 file... for example the 2002 Camaro file located at www.tunefiledepot.com ----> i.e. this one: 12212156.tun
thanks joecar , darcy i have read the tutorial. was a little confused , it only shows cos and 2-3 bar tutorial. i am looking to get cos5 for nos controls, i also read on the forumn that i need to first install 12212156 to get to the cos5 is this correct or do i just follow the 2-3 bar tutorial?
Start from either of these OS's (with the same transmission as yours):
- 12225074 Australian Holden -> upgrades to COS5 01290005
- 12212156 Camaro/Firebird -> upgrades to COS5 02020005
And then COS5 is included in the Custom folder of your EFILive V7 software install.
Yes, just follow the tutorial as if you're doing COS3.
Here are addiional notes specific to COS5: COS5.txt
Be sure to install the latest V7 build version from here: Update-Aug-24-2013
ok so i have full flashed 1222156 into my ls1b next i need to cal flash, my original cal ? or just cos5 sorry newbie!
when i try to cal flash it says cal not compatble?
No, You can't flash the cal from your os into another os.
Full flash the COS, then cal flash the 12212156 over it to populate all the calibration data, then follow the tutorial/notes on populating the remaining COS tables that will still be blank.
i think something is wrong, i full flashed 122156 into my 2001 z06 and many warnings are on screen for dic. service traction oil change that kinda stuff . are we shure this operating system for the camaro will work in my z06? just want to be shure i am on the rt track here, i am try to get to cos 5
