i will say that keeping that rear sensor clean and oil free is just as important as the maf sensors if not more so

VVEL is not like Vtec. VVEL controls valve timing on intake and exhaust. VTec controls the valves in Honda you have a extra lobe on the cam when activated these open all the valves will open using this hotter lobe on the cam. Now i-Vtec adds the VVEL to the mix with variable valve timing to the intake and exhuast for better performance through the RPM band.

Doesn't this sensor have a partner on the front of the other side of the engine, if you're talking about an actual VVEL sensor? Or are you talking about the MAP sensor that plugs into the top driver-side rear of the upper intake manifold?

i took that sensor out that is connected to the vvel motor that goes in the top back side of the im.it was oily.not dripping, but oily.so when you clean the maf sensors,hit that one too.

i also found this interesting;

I really like that PDF, good explanations I haven't seen elsewhere. Currently my car is in his "Stage 1" config. I have a really good quality baffled can on the PCV side, and stock hose on the fresh air side. (Well, our car has two of each of those lines, and I've run my PCV lines together with a Y-adaptor for a single can).

It's tempting to go ahead and run dual cans with his stage 3 setup for the NA 370Z, and I might get around to that someday. You could use the existing fresh air paths since we already have two of them, just replace those plastic baffled things with regular hose through cans, and then cap off the PCV valves and corresponding manifold connections.

i hooked up a 50a toggle switch tonight to my fans so that i can turn them on when oil temps reach 200.i hooked it up in such a way that it is totally reversable and does not interfere with the ecu.took the car out for some testing running it hard.

no hesitation for me and the car didnt lose any power.uprev fan mod is a must and i will be getting that sometime in the near future.for now,my temp fan mod stays and when i get ready to do some very spirited runs after car is fully warmed up,ill hit the switch and im good.

highest i seen my oil temp after this mod tonight was 210 where it should have been 225-230 with how hard i ran the car.it was 65 degrees out but the fan mod is still needed .25 row oil cooler before next summer and this hesitation should be completely gone for me.nissan surely made a big mistake programming the fans to come on when they do.thats 75% of the problem imo

its simple.the black wire on both fans coming out of the fan motors (the drivers side is tight to work with),peel back some rubber coating off of both wires.tie them in together and tape up accordingly.then run the wire into the cabin.i put a inline 40 amp fuse on it just in case.once the wire from your fans are in the cabin and hooked up to a 50a switch,simply ground it out on a seat bolt on the floor.now the fans will come on when you have the car on but they will not come on with the car off.you will have to take the overflow tank out or just move it over out of the way to do the drivers side cause the wire is very short from where it goes to the relay to the fan motor..
you will need;

one fuse holder with 12 awg wire and fuse
around 24ft of 12 awg wire
one 50a toggle switch(2 prong,not 3)

i will mount the switch tomorrow in one of the blanks by the cup holder.i had it laying in the seat tonight testing to see how it worked before mounting it.hope you have some patience cause you're going to need it.make sure to keep the switch off when you are running the ac.
