VVT auto-zero

[AbatelliCristian]

Hi guys,
is possible auto zero-vvt?
the current method, it is simple for the experts, but difficult for new installers.

My idea is this:
When engine is start, solenoid output is off. MS read VVT angle and use that value for minimum angle. For maximum angle i think is good "vvt minimum"+60 (in all engine 60 is max range for my experience). If engine have "range < 60" I think is not problem for PID.

good idea?

Best Regards
