Hi,
New problem found now when the car is ready to get tuned.
I can't get the cam angle to change at all. Cam offset is 583degs to get log show 0-1 cam angle when running and when I put ie. 20deg in the target table the solenoid DC rises, but cam angle stays exactly 0-1 all the time. Solenoid DC also goes up and down while idling, but I guess it's because I have set cam control from 800rpm onwards and the car has 272 bc cams and only ignition controlled idle so idle is not really stable below 900rpms.

What could be the issue here? Solenoid frequency is set to 133hz and basically everything else is left how the settings were. Do I have wrong wire from solenoid to aux output connected or wrong settings? Don't wanna try too much different combinations if someone has had a toyota vvti working with emu.

Any help is appreciated alot.

Well I wired a flyback diode right before the connector.
Something happened because the vvt-i cam gear stopped making noise and idle quality suffered badly (too much advance?). Well have to test more when I get new proper oil feed hose for the turbo.

Without vvti the spool is about 3700-3800rpm and one bar boost approx 4300-4400rpm. S363-sxe 1.0ar rear housing and E85. Hopefully one bar boost would drop to under 4000 when I get the vvti working and more tuning. Third gear lights up rear tires with only gas now

Vvti works now.
I guess the flyback diode did the trick and finding correct settings to operate the solenoid. About 175Hz, steady position DC 40%, PID control P, I, D gains on the low side below 1 for now. 5-10deg cam advance on idle gives nice rotary style idle operation.

Thank you. Working on a similar cam angle issue myself and this post gives me a few more things to try so wanted to thank you for posting your findings.
