Well, here's a disappointing update.
I received the UCON and hooked it up to my ECU, but unfortunately the car refused to start with it installed.
I double and triple-checked my wiring harness, everything seems to be working. Although the harness is all soldered up from the Perfect Power wiring, it does work without the UCON. I ran the engine with the perfect power only wired to the MAF, nothing else, and it worked:

And then ran the car without anything at all wired to the harness, and it ran, albeit very rich due to the larger injectors:

Talked to Scott from ITronix to trouble-shoot, he logged in remotely to inspect the software, he found that the software on the flash is correct and everything seems to be working except the Crank signal. He was able to see the MAF signal, Pedal position sensor, throttle position sensor, all except the Crank.
However, wiring the Crank directly does work. And I'm 100% sure it is the same pin location as in the FJ cruiser, because I have used the FJ wiring diagram to wire my perfect power.
I pulled the codes from the OBDII, and got an Ignition Coil codes thrown.
There are two possibilities:
1. The UCON is incompatible with the Fortuner ECU, even though it plugs right in without any problems. This is unlikely, because Scott confirmed that it was the Crank signal that wasn't working and I know it is the same wire used in the FJ Cruiser, and every other signal works perfectly.
2. The UCON has a defect. But this is also unlikely, because they tested the unit on a truck before shipping it. But if it were, then I'm extremely unlucky, because I haven't seen anyone receive a defected unit until now.
I sent it out back to Gadget to test it and verify its operation. Here are some more pictures:
The UCON plugged into the ECU perfectly:
Had to trim some brackets on the ECU mounting plate to make the UCON fit on the inner side, as it turns out my ECU is flipped upside down compared with the FJ Cruiser and Tacoma:

The UCON mounted nicely next to the ECU:
Looks so good, I sure hope it is only a defect, otherwise I'll shed some tears.
