APS dual port BOV - setup help please

[mrmr96]

Hi,
Just bought an APS dual port dump valve/blow off value/bov/dv whatever you want to call it. It was 2nd hand and has no manual.

It has a nut on top which I presume adjusts spring pressure? I've got no idea what happens if you turn it right or left... and even if I did I don't know what the optimal setting would be.

Do any of you have any tips on setting this up?

Thanks

I will try and help.
If you vacum pressure is quite high, say .6 bar then the spring will need to be stifferso it doesnt open on idle/ driving. If vacum is low then spring can be looser.

I would assume that a bit of trial and error may be the case, basicaly you dont want it to open to idle.

Try the above site though mate as i am an ametuer.
