my operating system # is 09260361 . i am looking to use cos 5 for my nitrous.
i downloaded the migration tune from holden crazy and i am going to copy and paste all tables from my tune to the 99 tune and save this bin and flash the pcm. then upgrade to the efi live custom op #02020005 and change all default parameters like the tuturial says. im going to try this, am i missing any important details thanks.

 

mate you sure a 99 tune is compatible with OS5. I know for the AUS cars it was an 02 cal that could be used.

 

Just make sure you are familiar with all the steps in the tutorial, then follow it step-by-step and you should be fine.

www.holdencrazy.com has a '02 OS with an stock '99 calibration available for download for this conversion to save you some copy/paste time.

If, for some reason, you get stuck on something, please post on the EFILive forum - help response is usually much faster there.
