Setting up VVT on an R34 RB25DET Neo engine?

Hey all,

We were on the dyno last night mapping the car using a G4 plug and play with a 5bar map sensor. Everything worked flawlessly

apart from the VVT setup. There were various selections including JZ, Vq35 etc but nothing for the NEO engine. Has anybody had any

experience with setting up VVT for the NEO engine? Apparently it's wired in on the plug and play?

since there is no VVT in any rb engine. You won't be setting it up. There however is a switched oil solenoid on the inlet cam which gives 20degrees advance. Your tune will be totally need to be redone. since the cam solenoid wants to be switched on from just off idle to 5300. (Nissan setting) this gives better Cylinder fill and around 40lbs of torque. You can use the cam solenoid option. I tend to just set a gp output. Otherwise you can find the valve clicking in and out at low tp and rpm.
