Erratic and flucating VTC angle

[maxbutton]

this is another car of mine.

Newly installed skunk2 ultra cams stage 2.

I am experiencing some form of erratic VTC angle. the deviation seems to be a little too much.

i did scour through the forum for information and conclude it might be a VTC sensor/gear/filter issue?

i did also check the battery voltage and it seems to be constant.

i have attached my datalog for reference.

any opinion or advice would be much appreciate.

apologies, newbie tuner there.=D

Just took out the VTC solenoid and gotten it tested. Working fine.

Cam gear?

Post the calibration the datalog was made with.
