Wolf3d V4 And Vvt

[QWK32]

recently i have been helping a mate install and tune a wolf 3d V4 onto a RB25DET NEO engine. it is a wire in ecu and as i worked through the wiring process it came to me that this ecu doesn't have the built in option of VVT control like th newer V500's.

now what i have been thinking about that may work is to use one of the wolfs auxiliary outputs programmed to switch the vvt solinoid at a set rpm, most probably through a relay. for the people in the know would this work?

or has anyone had any experience with the wolf V4 wire in on vvt engines? how did you do it?

also what rpm does the vvt switch? and whats the solinoids operating voltage? i'm guessing 12v.

The V4 Plus R32/33 Plug-in does have the VVT control built in.

I believe your theory should work, but i am NOT a mechanic so you'll better wait for a more experienced opinion

You other option is to contact AEM and ask them directly, they are always willing to help

yeah its the wire in so not vehical specific, and has no vvt function. and i'm sure its not the V4 plus, just the V4. basing this on the fact that it only has 4 ign outputs and 4 inj outputs. i have seen on the V4 plus it has the option for 6 ign outputs.

i'm fairly confident it'll work that way just need to know what rpm the vvt change over occurs at, i've read 1100 ish on and 5500 ish off, can anyone confirm this. and what voltage will activate the solinoid, 12v i believe?

Tha's how mine works. Actually, it uses 2 changeover relays, that basically switch VVT off for idle, switch on at 1500, then switch off at 4500 (roughly).
