I've never seen VCT disable like this with out showing some kind of sign to why. There are no temperature thresholds for OP. In your 2nd gear pull datalog, it still shows VCT disabling in the log. I use the air load channel for load, its logged.
As a last option, I'd copy over every table from the file I posted. Copy Borderline, MBT tables as well. "System" tab, "Trans" tab. Fan speeds.
Your logs show very advanced timing, knock retard, tip in and still shows oscillation even with the oscilation switch disabled. In your "crap pull" log, it shows you hit RPM Limiter at 6800RPM but your limiters are set to 7500.
I've compared your strategy to the one I'm editing and sending you. I've also compared it to some different strategies for missing tables. Having parameters set-up incorrect can cause strange things. I've only had VCT disable when hitting the rev limiter.
In spark advance, zero out Tip-in modifier. The strat I'm using has a different paramter for tip-in.
The OP Borderline and OP MBT I'm putting in test shitbox tune 2 is not stock. It's good, safe timing for 91 octane FBO and you can run that timing in the OP tables only. You can see how advanced your timing is compared to what I added in. I don't think the KR you have is false knock, i think your timing is too much at low RPM. The rest of the spark tables in my file are stock but copy them over too. Your spark tables should not really have the same values. Normally when people use the same timing for all tables their timing is not near as advanced timing as what you have. The changing airflow, air load, fuel, cylinder conditions, etc, from the cams transitioning will need different timing depending on how aggressive the cam angles are.
If it ends up still disabling VCT, I'd run a scanner or check for a mechanical issue. This more of a test for you to rule out the tune being the issue. Some of the tables I have in my file are stock.
Alot of time is wasted trying to tune out a mechanical issue.
I don't even run OP tables on my first gen and my OP/VCT is full functioning. Could be mechanical, maybe some kind of glitch or error.
