Megasquirt starts, then dies...

well, now I know that the coils are both good, as both will fire the T2 spark plug, with either cable. The coils will NOT fire T1.
The plugs are 5 minutes old, the wires are about 2 weeks old, and the timing light is about 2 minutes old.
I'm pretty sure that this isn't an ECU issue, since I can get electricity out of both coils. I just cant pick up a spark with the timing light on any coil that is connected to the T1 spark plug.

I found that I skipped step 65... for one reason or another, and saw the part about the pull up resistors. Was I NOT supposed to? I feel so dumb now!
I installed the pull up resistors, but not the rest of it.

HAH! got it. Like I said... the wiring was least likely.
The IAC2A/2B leads were swapped when jumped to the LEDs. I even thought about just swapping the 2 wires going to the trailing coil, which would have effectively done the same thing.
On another note... my friggin TACHOMETER IS FULLY FUNCTIONAL!!! everything is working! tuning time!

VE Analyze Live has gotten me up to 7.5 psi smoothly! Next step... maxing the factory turbo's usefulness at 10psi.
heres a good question though, about idle. When I lean out the area of the map at idle (550/720 injectors), my VE settings are around 21-22. That gives me a REALLY smooth idle. As soon as I place a load on the car though it obviously leans the f*** out, and tries to die if I dont catch it. If I take the table back up to about a 35-36 it stumbles at idle with a 10-11 AFR, but drivability from a stop is great.
So far I've set VE Analyze Live up to only tune with the fuelload% above 55%... that got pretty much everything running really well up to the higher end of the RPM scale. The lower end is whats confusing me now.

Keep in mind I'm still REALLY new at even the IDEA of timing... I've read a ton in the last few days.
Here's how I think I understand whats going on...
For the leading plugs, they fire at 5 ATDC based on the -5 in the "fixed advance" box. This tells me that 0 degrees in that box would set a baseline of TDC. However, since we have the "use table" option enabled, that 5 degrees ATDC changes based on the planned advance per the table i.e. -5 (fixed advance) + 22 degrees in the table (or any other in any cell) equals when the injectors fire (in this case would be 17 degrees BTDC.
Is this correct?

So, at idle - I'm running 20 degrees of advance. The lowest number in the table is 18, and thats about where I'm idleing at... on the higher side of that bin. I'll drop it down when I get home and see what happens.
