VVTi solenoid unstable - 2JZGTE VVTi Link G4+ Xtrem


Recommended Posts

Hello !

i have some issues with my VVT tuning. It's almost always jumping around its target, and i have no idea from where it could come ... I tried to increase the frequency but made no changes.

Do you have any idea how i can fix this ?


You can clearly see it on this part of the log.

Here is my VVT Setup


I attached the log and the related map (the map has been reworked since this log, but VVT issue remains)

Thank you !

Assuming your oil is in good condition, you have PID overshoot & need to adjust the PID parameters. switch PID setup to custom, & Either drop P by 1, i by 0.01 or 0.02, or increase D by 1-2. Make these changes 1 at a time then re-test. Dont make big jumps or wild guesses with this stuff.
