G4 plus PnP GTR34 hks v cam

Recommended Posts

Do you have the VVT Cam position sensor (Digital input) and VVT Cam solenoid (Aux Output) set up? If not you will not be able to see the target table.

Yes I have digital 2 input vvt cam position and aux 1 output vvt solenoid 

I can do cam test and lock the angles

i use vvt right intake as the map

but I only see tooth count , minimum DC clamp , maximum DC clamp

Hi Chester,

I think you've emailed me about this one. Would you find recording a PCLog of you trying to get the VVT going and also your current base-map?

Here is a video showing how to do the PCLog if you are unsure:

Would like to bring this up again as im working on 1 with the VCam 1 installed.  Dyno tunning will be get done by a Pro but i would like to get all basic setup done.  Just wondering the Vcam. Should be mechanically restricted which i should no where happen to blend anything fm starting up the engine.  Isnt it?  Im not going to touch the duty but just need the engine started and config those  minor things.  Tks

If you leave the control solenoid unplugged you will have the cams sitting at a safe position. (or just have the Aux turned off)

Yeap.. i was wonder there will be more information for HOW too.

As above mentioned AUX and DI for the solenoid and cam angle sensor.  There are also things about set for duty,  target map.  The tunner who will work with me would know how.  Im just install everything and learn fm him for how the other step to get this done.

For anyone else looking for HKS VCam info - yes the G4+ can run this ok.  Connect the cam position sensor to any DI 1-4, set as VVT cam position, LH Inlet.  Connect the solenoid to any Aux 1-4, set as VVT solenoid LH Inlet, frequency 250Hz.

Set VVT mode to Toyota 1JZ.  Do a cam angle test (explained in help file) to get the correct offset for the digital input.  VVT PID needs to be set to custom with P=5.0, I= 0.04, D=20.

Hi Adam,

I have another question.  Since i could only  Use Aux 1 to 4. But fm 1 to 8 are all occupied except AUX5 which no pin# shown in manual.  Is there any hidden aux output there i can use?

I will need to move out both AC in and out to have room for aux 3 and Di4 for the vcam.

Thus,  they both need to assign to another aux/Di. Di4 seems to be ok to di9 fm expansion 2

Expansion 2 aux11 for the AC out???

Many people with performance GTR's dont use the fuel pump speed controller so that means aux 1 and 2 are available.  But if you want to keep the fuel pump controller then my suggestion would be to move the AC clutch and AC request wires to aux 11 and D9 on the expansion connector so that frees up Aux 3 and DI4 for the VCam.
