vvt

Hello guys, I need your help, my 2007 MS6 have p0012, the PCM is not sending ground signal to the OCV, if I manually add ground to the valve the VVT moves. Is there any ground related to the OCV? Anyone know if the ECU from mazdaspeed 3 is compatible with mazdaspeed 6?

New to this board so bare with me. I have a 2008 MS3 that I have owned since new. Not many mods except suspension and some mounts. Car has 135k on it. I started hearing ticking from the timing chain area on startup. Would go away after a bit. I also started to notice on hard...
