I had similar spikes on a 2JZGE VVTI with BC272 cams using Kurofune. Had to mess around with trigger two arming thresholds a lot to get the system happy and not spike. Required much more arming voltage than other 2JZ's Ive done. Unsure if its down to the ECU or the engine combo.
Looking at your latest map you have your VVTI cam control mode set to Off, and in the logs the ECU is not able to track Inlet cam position. This could be contributing towards your sync errors. Haven't ever tried running a VVTI with cam control compeltely off, normally if I want to diagnose VVT system I just set RPM lockout very high. ECU still tracks inlet position like this which is helpful in diagnostics. If your VVT solenoid has no duty then the cam gear can bounce, especially on idle and free revving.

Always struggle to get ASNU injectors to work like they should, their provided data seems like its miles off for some reason.

Ditch the EVAP control (purge) and run EGCV on AUX 9. Keep stock idle control valve as it works well, even though it does use a lot of outputs to run.

Wire your coils using "Vag Coil Normal/Long"
No need for stock igniter. You can delete completely or just bypass.
Run your ECU signal wires direct to ECU and repin/rewire your signals to B57 - B52 on ECU pinout.
You can take your 12v from the igniter wiring, or there is grey 14 pin plug in passenger footwell that supplies voltage to igniter & coils from factory, you can wire to this as well if its easier.
