That looks totally wrong.

All the "InVVT (Actual)" logs I've seen for RA and Evo X track pretty closely to the "InVVT (Target)" curve. No see-sawing, so crazy stuff.


But... I'm honestly not able to offer any suggestions as to WHY this is happening on your vehicle. Not a pro tuner, and I haven't tinkered with the MIVEC hardware (or cams).

Thank you, anyone else? Am I really the only person seeing this?

Have you checked the oil pressure? Olso IIRC the intake cam has AL bearing, wrong gap/wear?

I have the sensor for my zeitronix but haven't installed it yet. Need to. AL bearing? Aluminum?

ZZZ

Yes, aluminium. Just random guess. Actually I see up to 4* actual - target difference in my mivec at some rare points.

What was the resolve here?

Nope, I just learned to deal with it. It's always my intake cam. Might be the intake mivec solenoid... I've rebuilt the motor with a new oil pump and cam bearings so I know it's not that. Oil pressure is very healthy at all times.
