andpdas Posted November 22, 2018 Report Share Posted November 22, 2018 I have Subaru STI 2012 EJ207. My Engine has both intake and exaust VVT. At first, I have used the default cam settings "Subaru Quad AVCS". But it didn't be stable. I am using custom pid settings but sill not stable. I have read the help page in the PCLink about the custom PID settings. I also understand about how the PID works. But I can't make it stable. Could you look at my settings and see if I had messed up something. Or, any prefered values?GVB-22L - コピー.pclr Log : https://drive.google.com/file/d/16AIBPA81snG-T_0r1Q5aQA6OrRvFkNTV/view?usp=sharing Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 23, 2018 Report Share Posted November 23, 2018 Your Intake cams appear to control well once the oil is warm but are a bit unstable when cold. You may be able to improve this using a higher/lower minimum and max clamp when cold and posibly reducing Proportional gain a little more. I would try min max clamps like this: For the exhaust cams, have you tried even less proportional? Like say about 1.5? Quote Link to comment Share on other sites More sharing options...

andpdas Posted November 23, 2018 Author Report Share Posted November 23, 2018 I have tried changing both clamp table and proportional. It went pretty well on the exhaust right cam. but not on left cam. I have swapped to the stock ECU and took some logs. but both right and left exhaust cam were stable. I think it is not a mechanical problem. Should I use separate PID settings for right and left exhaust cams? And do you have any idea why does my left exhaust cam are going up and down.https://drive.google.com/open?id=1AjfPYF8nR7Jw-arvEXf-mMwlgSiQ4q1uhttps://drive.google.com/open?id=11oXq1Vj5YbyYr2Lu0Oi89E_y6qlxHNX5 Quote Link to comment Share on other sites More sharing options...
