I'm pretty sure the SAFC is unable to control the VCT. The way VCT works is not like how V-TEC works in Hondas.

VCT on a stock car disengages aroudn 4700rpm where as in a Honda usually it engages at a higher rpm point.

sorry for the confusion... ok currently the car feels sluggish with no response so i want to check where the VCT plug is i want to make sure the VCT is functioning....

If you're standing in front of the motor, it is on the LHS, where the plenum is.. kind of hard to explain without a photo

and yes NEO has V-TEC control but like I said before Nissan's VCT is TOTALLY different to how VTEC works, so no you cannot rig that shet up.

Car running slow? try disconnecting your SAFC, you've probably have the car running rich as.

it would be strange that VCT would magically die

i dont think we see very often that VCT dies

are you sure it's just died?

has someone been fiddling and then you think it's died?

have you played around with the wiring loom before hand?

just purchased the car a few days ago.... shoulda looked into it when purchasing... but yeh fed the soleniod 12V at idle and while the engine was off no click no nothing...

so this is what i know so far, the ecu is feeding the soleniod the signal (tested the plug with multimeter while reving in gear)

car drives the same plugged and un plugged( can feel power arnd the 5-6K mark but nothing before)

the soleniod is not making and noise when fed 12V

anybody have any suggestions in what else i should check? what could cause VCT death?

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
