Yeah thats 12P in the zip, but the older v1.1.1 - not 1.1.2 which most people are running these days. Only a couple of minor changes between those two versions from memory, but still should always use the matching xdf.

Yeah sorry, I forgot to mention it's the previous 12P, was thinking of moving any mods done to this to the v1.12 since it's what's on the nvram I bought from here, though wondering if there's any benefit from doing so.

Also, keep in mind, I have no intentions of making a living out of continued use of this info given & parts bought from here.
I bought the VS stuff because my son was pushing to, and figured it's better we do this as a project together, than he go elsewhere, and this 12P involvement is because the fellow that has sent all his carb tuning work my way for years has continually asked me if I wanted to get involved when he's built motors, I don't want to get too involved with this scene just yet, if at all.

I don't want to hijack, but even using V1.1.1, I'm still seeing ve tables that look a saw tooth, lots of other things that have extremely high numbers etc. Am I doing something wrong?

If that's 12P theres something really wrong. Either version XDF should show the same VE tables but if your sure it's 12P it's a mess.

I compared the dump from the fellows ecu with all ose12p's from here using a hex editor, and found it pretty much matched the "OSE $12P V111 APNX V6.bin" from the download of 111 here
The ecu itself also has apnx written on it with a black marker.
No idea who tuned it before.

Must run real bad lol timing control is turned off so its locked at 10 degrees timing everywhere has all the cold air fuel tables disabled and lots of other strangeness

Is it a botched attempt at a Methanol tune?

Yeah most likely. I'd call that porcupine, not saw tooth, and I wouldnt use it as a base. You'd be far better off reading Holden202Ts of how he did it, and modify a stock tune to suit yourself.

Yeah I'm kinda leaning that way myself.
Another thing, past experience with A/F meters on dyno's have led me to being sceptical of their accuracy, many occasions I've either pulled or added fuel from tunes then thought to myself, nah, check a plug, and found the plug tells a totally different story, then gone the direction the plug tells me and gone forward, only to hear the dyno operator state yeah I replaced the sensor a few days ago as it was playing games {or a story along the same lines}.

Since techedge is 30 odd k's south of me, should I consider my own wideband, the old microtech unit I had died on 2 of the LEDs, and they use some funky +common terminal led units that I cant find online for the life of me.

What if he's done something like you mentioned here, and advanced the reference angle to make it start / run better, doesn't that not only advance the timing reference angle, but also the crank angle at which the injector fires.

You still get completely flat timing though. Just that the flat timing might be more than 10 degrees. Definitely sub-optimal.
