Has anyone tried adjusting their cam position while not in Optimum Power. Meaning changed the Intake and Exhaust Mapped points. Or have a 2013/14 with a lumpy cam idle?
What i'm running into is I am trying to achieve a lumpy cam idle by moving the Intake and Exhaust cam position to my new targets. I feel that I have a pretty good understanding of how the cam positioning works. Unfortunately I can not figure out what is causing the I/E cams to move to 0 degrees after 20 seconds at idle.
For example start the car let it idle/warm up for the phase limiting. Blip the throttle to rev the motor, engine returns to idle at my target position I requested and stays there for 20 seconds. Then the cams will zero out and go home every-time. I originally thought Optimal Stability was causing me this grief but I can see it moving the cams before the 20 sec period when the cams move to home.
If the throttle pedal is any value other 0% then my target position will be held. If the throttle pedal position is 0% and 20 seconds passes the cams return home. I'm wondering if one of the Snap to Point tables are my issue if I am entering into an cell that is not enabled. If I set all of my Intake and Exhaust Valve Closing tables to a value other than zero. I still see 0 degree's as my target value on my scan tool once the 20 seconds expires. Anyone run into this yet?
One thing I'm not sure about is the VCT Best Driveability -Enable Min Load. The table has load points in the 60% to 70% range at 1000 rpm and up. To me this load point is to high to be considered a Driveablity table. Is it possible one or more of the tables is mislabeled or the values in the table are not correct for the actual usage of the table? I would love to hear what others have done or see a file with the lumpy idle in it.
Thanks guys,
