Pfc Boost Kit Solenoid Wires R33

[dangerman4]

where do you connect the solenoid wires on a r33 s1?

i have read thru Pauls faq sheets but that doesnt tell me.

from what he says it plugs in, but the plugs arnt even close

to fitting, so do i have to chop an solder or what?

yeah just cut the wires

it re-uses the stock boost solneoid wires

its basically constant power and switched ground

the switched ground runs to the ecu loom, wire 25 from memory

how can it be constant power and switched earth if you say to high boost a standard car you ground the earth?

if you have constant positive and constant (ground earth) then its going to be full open not opening and shutting 200 times a minute or whatever speed it works at?

can you clarify for me?

the stock 33 solenoid is a open small width, open large width type solenoid, its not an open/close valve. the pfc boost kit one, the same as the avcr is an open/close valve, so it switches it on/off radidly to drive the boost pressure. the stock ecu and the stock solenoid switch the ground over 4500rpm to close it up a bit more, so the gate creeps a little to give some more boost pressure.

the stock ecu and the pfc boost controll systems both use the same wires
