How is the variable timing activated?

[slindborg]

I know there is the dephaser pulley, but is there an electronic valve that opens an oil channel etc to make the timing change on demand (eg engine speed/load)

cheers

yeah the solenoid

 

[slindborg]

Simple trigger it to advance/r****d X degrees, or is it PWM controlled to try and trim the timing? (Is there feedback as to how far the depahser has moved?)

 

[Fred@BTM]

16degrees, off or on

Ohh agricultural, I like that Also keeps things a lot simpler for my cunning plan

Thanks Fred

 

[Fred@BTM]

why what are you planning?

 

[slindborg]

I love the concept of megasquirt, but I loathe its current implementation.... lost of non automotive grade parts, lots of un-necessarily out of date components and protocols etc.

My plan is to start small and redesign it to include ETB control and a few other bits and pieces that would make life easier when calibrating and see where the land lies.
