I have been trying to get 01290001 to work on my 2003 Holden SV8 but have had a few glitches.
In ScanTool there are no parameters under EFILive Custom Calibrations for lean cruise etc.
When logging GM.ASPARK it is always on 0% which seems to indicate it is not using the Hi Octane table.
Using exactly the same tune I can load it into an alternate OS and both these problems are solved. Any clue what may be wrong?
