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 :P

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

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).

    • I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to some I’ve seen though 
    • $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.
    • Time for a modernisation, throw out the AFM, stock O2s, ECU into the e-waste bin. Rip out the cable throttle, IACV, pedal, etc. into the scrap metal bin. DBW, e-throttle, modern ECU, CANbus wideband, and the thing will drive better than when it left the factory.
    • I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis.   I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics.   The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.
    • I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later.
