stock ecu, maybe with a raised rev limit. then dyno (unless you have a wideband setup) to check the air fuel. then use a air fuel controller if need be. aftermarket ecu's are tuned to one car, then mass produced, thus not releasing the full potential of your car with your mods. why spend money on something that wont live it its fullest.

So we've established which software is, and why it is, the all around best.
We also know that we still have to send off the ECU to get the rev limiter raised.
And with the paramters that we're dealing with here we also know that it isn't feasible to swap out the entire wiring harness to use a 2k2 ECU. We're going to use a ECU which is native to the vehicle, most likely a '96.
Anyone want to fill in the blanks here?
Keep in mind, software and hardware (ECU) are NOT the same thing.

OBDII->OBDI harness adaptor: 150$cnd (115-120$US)
Both together: 500$cnd (400$US)
We're probably going to use the cam sensor holes (one on each cam) that the VQ35 uses. Both of those sensors are in my car and useless for now (just to seal the holes) but they will probably be replaced by the sensors compatible with the 300zx ecu. He's going to take one out of his RB26 and see if the size of the hole is right, since it is directly in front of the cam. This COULD mean that future VQ35 swapers could do it without going through the whole timing chain ordeal or going through all the 2k2 wiring BS.

All they would have to do is copy and paste those a/f and timing maps onto a daughterboard!!! Brilliant!!! Damn...good thinking SR20. This is sooo much easier on them than making a modified map. I'm sure they could have a 3.5-spec ECU in production in no time.

It isn't a new idea. I just never got the opportunity to use it so I am essentually giving it away.
There is more to the story that I can't give away becuase the rest of it is co-owned by someone else.

Anyone experiementing with intake manifolds could get away with a 350Z map. Which I almost did on my car when I got my L-Spec. I just didn't want to spend the extra $200 at the time. But later this year I'll probably go through with it. The cam timing curves on the FWD cars are not what they should be. I even got Tadashi to verify this when I spoke to him last Janurary.

I don't know if the VTC is software co-dependant of the tune of the car. But I am certain it is co-dependant of the VE (volumetric efficiency). Therefore the 2k2 3D map will have plenty of answers for all available cam settings at each RPM. And any software dependancies should be irrelivant. Especially since the '96 ECU won't even have settings for the VTC.
But everyone take note that I never said you had to toss the VTC. It will however be ALOT of extra work to keep it though.

SR you are a true asset to the maxima comunity!
Would a company such as TS be able to transfer the fuel maps and timing maps from a VQ35 to a VQ30 ECU? Would it provide better gains with the 350z or g35 maps than the FWD maps for a non VTC VQ35?
Also what would be the starting point to get VTC on a VQ30DE ECU driven VQ35, multiple RPM switches, somthing similar??

I have a plan in the works but don't want to say, not because I like to keep secrets but I would rather have it working and post dyno results.
End users will be able to tweak and program the VTC functions and this should also allow us to use the NISMO VTC assemblies for even more advance. This should in theory allow us to run more radical aftermarket VQ35 cams and still be streetable.
