Can VVT be enabled on a non VVT tune? E67 2007 CTSV

Here is same OS two years ago, the earliest I can easily find:

So the 2011 holden comadore and 2011 Camaro have the same or different OS? Still can't open those files

I'm not sure what you mean? If they both have the same OS, Efi will let out swap different segments, along with there associated checksums. Not just a copy of some of the tables, I mean the complete segment, you will need to save the file ad reopen it though, then you will see that the segment number and checksums have moved over. If you want to swap a engine segment from a different OS, I can manually do it, but it will likely say an error or brick the pcm when you try to flash it. I just tried that with my E67, and it barely ran, wasn't happy about the segment swap at all. If you have the files as .bin they are raw and unencrypted you can then segment swap your self even incompatible OS, but it will likely not work, and risk seriously messing it up! If you have a hp tuners I can convert those file to bin. but efi you cannot convert the files or save them as a bin, you can hover open, and edit a bin file, and write it to your PCM.

Oh righto thanks, I'll try saving then reopen...

Yahoo, it worked! Standby to see if it bricks my ECU or I have VVT spark.

OK when you're next in Australia I owe you, and we brew some good beers down here. All good, works brilliantly, thanks!

Yes, a segment copy copies the visible + invisible data... so you have to do a full flash.

I'm glad it worked:)

Yeah as in prior to this, with high squish smallest chamber running 26deg spark advance @ WOT on e85, made peak power at 6300.
I concluded after scores and dozens of pulls different scenarios bloody thing preferred phaser locked no retard (no point having VVT).
I thought it must have been a bad cam choice, and I was also happy to ignore the whole notion of VVT spark as It seemed I could add advance through the main spark table anyway so didn't matter VVT spark table wasn't working because it was redundant.
Well Yeehaa...

Now VVT spark advance opens full phaser movement with torque plateau higher and longer, as expected, but not like this: WOT pulls on exact same 26deg main table advance plus 6deg VVT spark advance is 32deg on e85 @ 13.5:1 - torque pulls like a filthy monkey at 5900 [emoji205]
So all good, truly exceptional performance now.
