VR VVT issues #128

Closed ElDominio closed 1 year ago

ElDominio commented 1 year ago

In this log i change VR threshold for cam input, and the cam angle changes, I don't think this is right, started at 0.3 and kept adding .1 until i got to 1

you can see VVT angle change as i change VR threshold

Trigger scope looks fine. Your triggers are configured correctly for what I see on the scope.

Thresholds also look fine, you can set them pretty high once the engine is running. Not sure why you're seeing timing move with threshold level.

Aside: why does the VVT position move with RPM?

ElDominio commented 1 year ago

Because I targetted different positions with RPM? i guess lol

I set inverted to True and it seems MUCH more stable, as in useable. I'll close this for now since it seems to be okay
