The 350z does not have a Crank REF, it has something like a "combo" sensor(REF+POS)
The SMT could read the RPM's on the VQ35 just fine, the VQ30 is where hte problems were at. (pointless info
)

Just because the 350Z uses a sensor configuration that the '95~'01 Maximas don't have, doesn't mean you guys should use the POS sensor.
Again the REF signal is used to determine TDC on the 4th gens and possibly the 5th gens (I think Icey's FSM is a mistake). TDC is what you would want to know when determining timing. POS sensor on our cars tells the ECU what rpm it's at. The SMT-6 only needed a REF signal to determine both RPMs and timing advance, so why can't the EU? Greddy needs to get off their asses and program a VQ30 crank and cam into this thing or it will be a "non-event".

Another mini update
Just got off the phone with Kenji. I am reasonably optimistic this will get fixed, even if it takes a while. He will be talking to Japan to see what's being done with the VQ30 and I should hear back in a couple of days. Apparently Greddy USA and Japan both have been inundated with calls from customers saying "my application isn't working." Surprise, surprise. He says Japan is working on adding applications to the firmware but starting with the most common/popular ones and working down from there. Who knows where the VQ is on that list, probably not at the top, so it may be a bit of a wait.
However there is a silver lining in that the flood of complaints seems to have caused Greddy Japan to begin working on something they should have done in the first place - provided a user-defined setup. Apparently they are now working on revamping the software/firmware such that users will be able to set up their own type of airflow meter, crank signal etc. He couldn't give any more detail about it but did mention that they are aiming to release it by the end of October.
I'll post again when I hear back from Kenji.

I've got that solved...I think. If not, it's not a misfire, it's just the ECU not seeing a load, ie the coil, but it's still firing fine.
I'm going to use it to scale injectors, switch my VIAS sooner, activate/deactivate N20, retard timing, switch maps, activate shift light, logging signals, yada yada, some of them at least.
I don't suspect the crank signal is necessary except probably for advancing timing and bumping the rev-limiter....maybe not...I was hoping you'd try those before I got to it.

Your list sounds very similar to mine too... except for the N2O. I'm also using one relay for my fans in combo with a lower temp T-stat.
So what did you do to resolve the CEL? What was the issue?

I don't have a WB yet, but it's on my list, same one Neals' got. Don't really need one yet though. Just dump more then enough fuel to know you're super rich and pull a plug or two.
Yes, I have an OBD logger, which displays/records timing.
I haven't done the fix yet, however John@J&S has told me what the problem is and through my reading, I'm 90% sure he's dead on the money. It just takes resistors to act as "coil simulators" acting as a load to the ECU, when the emanage isn't firing the coils.
I've got the resistors and a breadboard, so I'll test it out once I score another laptop. This would have been solved already, if I had a laptop and I didn't pretty much get heatstroke last weekend.

EDIT: oh just saw your other post re: the "fix" from John. Doesn't sound too bad.

Another update
Well, I haven't heard back yet from Kenji. Seeing as it's a long weekend I'll bug him again on Tuesday. In the meantime, I've been playing a little.
First off, Icey I checked into the Analog Input/Output settings and as it turns out, the pinout chart on page 11 is correct. The picture on page 19 is not. (ie- input is pin 31 (w/gy) and output is pin 37 (gr/gy)).
Second, I tried the rev limiter and could not get it to work. Mind you I'm running rpms based off coil signals, perhaps using the crank signal it may be different but I suspect not, as I think the problem is more likely the VQ30 ECU and how it cuts fuel. Either that or the Greddy needs a bit more programming to extend the hold time long enough. You can only set it to 5ms max right now. I will discuss this more with Kenji when I talk to him.
Third, JClaw the A/F map works nicely (I didn't expect any real problems here, no matter the rpm input type). I spent some time tuning for WOT and dialed down my JWT from 14+ to 13.0 across the range. That should be good enough for now until I get on a dyno in a few weeks time. I did not use the Autotune feature because of not having the Zeitronix wired in yet, so I just flipped back and forth between the datalogger and the EU but it wasn't that tedious to build the map. At some point I do plan to connect the WB just to test how it would work. I still need to wire in a couple other things, such as my VIAS.

I dont think the revlimiter will work w/o the crank or cam signal.
After all, the EU needs to drive the coils and injectors so it can't get a higher RPM reading.

Yeah I'm not surprised it didn't work with only the coil signals. I want to talk to Kenji about this more though to better understand/confirm exactly what the EU is doing for this feature (or would be at least if it had a crank signal).

I got a P1320 last night with the 96 JWT, but didn't with the 98...
But you're right, it's not misfiring, still runs smooth. I've got the EU in the car full time now and controlling my VIAS also. MUCH easier (and more accurate) to set than the Summit.

Well it's not a relay technically... you use the NVCS map, but if you go to the I/J setup under either CH7 or CH8 and right click you can select NVCS. The EU then supplies ground on that channel when it sees the "ON" value at the various setpoints in the NVCS map.
I'm using CH8 as a relay to control my fans (supplies +12v) and CH7 for the NVCS (supplies ground).

Quick update
Talked to Kenji again. He has been in contact with Japan and they have already had a request there for the VQ30DET so apparently their engineers are working on/will be adding it to the firmware. I will be emailing my scope signals as well as some FSM scans to Kenji and he'll pass them on.
Also discussed the function of the rev limiter with him. I believe I have a good understanding of what exactly the EU is doing now. Kenji has not tested this feature but thinks it will work once we get a crank signal as the EU can drive injection itself without a signal from the ECU as long as the ignition isn't cut also (as far as we know this is the case for the VQ30).
But really there won't be a definitive answer to this until we have a working crank signal. We'll just have to wait for the firmware update, which from the sounds of it, may not be as far off as first thought. *keeping my fingers crossed* haha.

Of course if the rev limiter turns out to work on the EU you just might have to come over to the dark side.
