Like wise. Lots of knowledge and know how in this forum. We need some sort of national clublexus meet with everyone on the forum to go! lol would be wild...
Forgot to mention!! I order the front pair of CCW Race Classic wheels in 18x10 today and new hardware for the rears! should be here with in 3 weeks sense they have to be machined and assembled. Cant wait!

Those will be looking super sweet on there... I just hope none of us wrecks our SC's. We have so much money in them, it is ridiculous. I almost sat down the other and start to count the receipts. I was like I need to quit while I am ahead. LOL

haha you know what I did the same with my drift-motion account and said, ok time to look away and order some parts lol But yes wrecking our cars would be a huge let down on all countless hours and man power we put into them. But hey its like woman, cant live with them and cant live without them lol jk

Going from the AEM v1 to the V2, the coil pins are pretty much backwards.
AEM V1 coil Pins:
Coil 1 > 52B (IGT)
Coil 2 > 53B
Coil 3 > 54B
And so on..
AEM V2 coil pins:
Coil 1 > 57B (IGT)
Coil 2 > 56B
Coil 3 > 55B
So you can see the three that needed to be moved.
Flexfuel sensor has three wires: (I used a vsv solenoid plug for 12v, signal to the aem and ran a ground to intake manifold grounds)
Out > 21B (available switched input)
GND > Intake manifold ground or chassis ground
VCC > 12v

I am trying to understand why is the wiring different? V2 is pnp to supras and SC with gte swap so in another word if the wiring was fine on the V1 why would it need to be redone when you use the V2.

That is exactly why I was confused as well Omar.... If you look at the v1 pin-out sheet vs the V2 pin-out sheet you will see that they are different. The Sheet for the 30-6101 v2 also explains at the bottom that a few pins have been changed and no longer match the 30-1101 EMS. I never bothered to read that part up until I was troubleshooting why the coils wouldn't fire. Turned out to be those three wires where in the wrong pins..
I guess you could just turn on the coils 6-4 to make it work but to me that would make things confusing when referring to coil #1, Coil #2, Coil #3. I like to keep the number sequence the same. Seems easier in my mind.

Its different because when people made those diagrams for the v1 using pins 52-54 is the same as using pins 57-55 since in the aem pins 52 and 57 are wired together internally, 53 and 56 are wired together internally, and 54 and 55 are wired together internally.
so if you wired up your vvti coils on the V1 to 52-54, you will have a problem with the normal vvti coil settings on the V2, but if you wired them up to 55-57 then you won't have any issues with the vvti coil settings on V2 (where you just sett up the B parameters for coil 1-3B to look like 6-4).
on the gte ecu and the v2 they are individual so you can't use that trick anymore.
So if you look they change 54-52 to be coil 4-6 which follows the gte designation.
Omar is right the v2 follows the GTE numbering, so:
57 is IGT coil 1
56 is IGT coil 2
55 is IGT coil 3
54 is IGT coil 4
53 is IGT coil 5
52 is IGT coil 6
58 is always IGF (not needed for aem)
whole gte pinout

Since the stock coil wire is in 57 and generally re-use that pin/wire lead, I usually wire vvti coils to 55-57 anyways, and then you can swap with no issues, so It didn't occur to me that could be your problem. It is still good info though I am sure it will happen again to someone and they can hopefully find this thread.

I made another stupid video lol Kinda gives you guys a better perspective of what was going on after I swapped out the three wires. When I plugged the ignitor back in, I managed to bend coil #1 pin which is why it sounds like crap in the beginning because coil #1 was not firing.

So I took the turbo off to get a final check before it hits the dyno. Its probably fine but why not get it checked anyways. I should have it back by Sunday from my buddy Jim at APT. Plus I've got other things i need to finish anyways.
Few more things waitng to be installed and I don't think I ever posted pics of the AEM and wiring in the cabin. This is when I was trouble shooting the no spark issue a few days ago.
ARP wheel studs to go with the CCW's
Wire Size for the extra things is probably over kill but its what I had laying around..
Labeled all the wires I either added or moved just so I know what they are if I run into anything funky.
Notice the ignitor with the ECU?
moved that so its not an eye sore in the bay

I am running lq9 coils on my Na-T setup and I had them wired in like a gte 30-1100 diagram. I have to double check all of my wiring and add the wideband wiring to the AEM v2. When you welded the AN bung to the flex fuel sensor did you get aluminum or steel AN bungs.

Yea I wish I would have gone lq9 as well but for now the vvti setup will do what I want it to do. For some reason I keep getting the 700rwhp number on e85 stuck in my head but I doubt it will get there with the vvti setup. But who knows. Omar ran 703 on e85 bit not sure of that was on the vvti setup. Anything over 550rwhp, I'll be happy with 
For flex bungs, I got stainless steel bungs than welded them on. You have to be careful not to get it to hot or you'll melt the plastic part In he middle that's holding the tube. So take your time and do a couple beeds at a time and let it cool In between passes.
