Hi everyone,

I want to use link G5 to install it on Lexus 2ur-gse and Nissan vr30ddtt engines,

Can Link G5 control Lexus' vvt-ie and Nissan's electronic variable valve timing control (vtc)?

Thank you.

The 2UR-GSE is what we use as one of our internal test platforms with full control of VVT-iE.

The VR30DDTT has dual e-throttle and dual electric wastegate control, which would require the use of external H-Bridges(Ehtrolle) modules to control.

I'm unsure of the specific for VTC  control but if it's similar to VVT-iE, then the Voodoo Pro can control it.

Thank you for your quick reply.

Just wondering is there any further information about how to make all able connections?  Such as a description or simple diagram about how to connect them?  Or is there any way to purchase the all-cable-connected set? Thank you so much!

To give a bit more information about the 2UR cam control - although we have it working nicely on our test engine, be aware there is not yet a nice user-friendly built-in control strategy for these cam motors.  Im currently doing it with a fairly complex arrangement of GP PWM tables.  I need to spend some more time on it to specify a built-in function with a lot of this complexity hidden from the user but I wont be able to for a month or two due to other priorities.  We can give you a map with it all working and controlling well and I dont expect it will need any tuning or adjustment but it is not currently easy to understand if you needed to adjust anything.  Adjusting the commanded cam angle is still tuned in the normal way with the VVT target table, just there is a whole lot of other stuff working in the background to translate that into a motor demand.  

Note it is a very IO hungry engine and the wiring is complex, I can probably give you the drawing from our loom but it really will need a very experienced wiring guy to build it, 16 injectors staged DI/port, 2 DI pumps, 5 cam sensors, 4 knock sensors, 2 brushless motor controllers with diagnostics on the intake cams, conventional hydraulic VVT on the exhaust, E-throttle etc.  Our loom has a little more complexity as we have sublooms to quickly swap between different injector driver boxes.

I have checked with our technician, We think we will be okay with the wiring. It would be great if you could kindly provide us with a wiring diagram and adjustment map. Thank you so much, we appreciate your help and support.
