Working on a custom operating system without having pcm handy.

[spoolinsteve]

Hello all, I was wondering if you guys can help me some more.

My car is all apart and I do not have a bench harness. I was working on my tune and setting up certain parameters so when the car does come together I feel I will have a solid starting point.

I have decided to go with COS5. Is there anyway to create a calibration that includes COS5 features without physically reflashing the pcm.

I have played around with swapping segments and I cannot get the "Copy entire segments > EFI Live custom operations" option to be highlighted no-matter what I do.

Is this possible? Or what is the proper way of doing such a thing?
Thanks.
Steve

Go to the holden crazy site & pull a tune using the COS you are wanting to use. Then copy the segments from your tune onto this template. If there isnt a tune on that site, there is sure to be one on this forum somewhere.

I think there is only 2 OS5 variants, so it will be very easy to find the one you need.. ie not the Aussie car one.. The other one.
