Setting Up Vct Switch On Rb25 (freq. Sw. From Jaycar)

[TiTAN]

have you thought about just having the vct active at idle and using a shift light to turn it off via relay @ the RPM set to turn the light on??

Car idles like crap with VCT on at idle. Any ideas on the amp draw of the vct solinoid?

[Crans]

MSD switch installed found out vct should draw around 1 apm so no relay needed.works perfect easy to setup but expensive $280.

If it's only pulling an amp i'll rip the extra relay out of my setup once i get around to setting the switch point and tidying everything up. I only just chucked it in half an hour ago and then it started raining again....

Car feels so god damn smooth compaired to driving with vct always off. search ebay for rpm switch there are afew cheaper options sub $100 but i couldnt be bothered waiting

Old thread but I thought I'd put some extra advice in here for anyone searching, I used an eboost street to control my VCT, it has an RPM in wire and you can set it up to turn an aux relay on between 1500 and 5000rpm very easily.

Works a treat and the car makes an extra 15kw in the midrange with it enabled, you also need far less throttle driving around town to make the same power.

Why does it need to shut off at 5000 rpm?

Pretty sure pfc's dont shut it off..

[TiTAN]

they do shut it off.

it hurts top end power if its not shut off.

Power FC's are the opposite. The setting is the RPM you want it to turn off.

The VCT is only needed in lower RPM.

This is how it works in simpe terms. Its not on at idle, I think it switches on at either a certain RPM (Which is low anyway, just above idle) or once certain conditions are met (like throttle position/load etc) But the adjustable setting with the Power FC is for when it will turn off

EDIT: Why was it necessary to dig up a thread from 2010 to point out a (wrong) fact?

I'm surprised no-one ever worked out that you can series up 2 of the Jaycar units to make a window switch.

Because it will kill power...
