Changing from COS3 to COS5

[cyipher]

Have my tune spot on, on a COS3 OS and am looking to convert to COS5 so i can use nitrous controls. My base OS isnt listed for COS5 so i have to change base OS's how much of a change is it to convert the base OS to the 01-02 camaro OS as far as tuning goes? is my VE table gonna be close? what else needs to be changed other then injector data and engine size?

Thanks
Kyle

Hi Kyle,

If you can find an already-populated 02020005 file, just copy your tables over to it and flash it directly (i.e. avoiding 12212156).

If you don't have an already-populated 02020005 file, you can make one...


full flash in 02020005, cal flash in a stock 12212156 file, then read it out and save as 02020005_0000.ctz, then edit this to contain your specific tables (the ones that are different), save this as 02020005_0001.ctz.

but if i flash in my injector data, ve, and timing is it gonna be close or the same, since im using a truck os now?

You might need to copy some of the other tables, for example idle and other stuff (any thing that is different).
