AEM EFI starting & tuning (Gen3 426)

After 2 years of work and excruciating anticipation, I'm finally ready for the first fire up! :blob: I have a 66 Cuda with a brand spanking new Gen3 426 Hemi, controlled by a Mopar Performance AEM programmed ECM (gray box P5153528) with accompanying wiring harness connected to factory style sensors. I've checked to ensure power, switched power, and grounds are all properly connected at the appropriate pins on the ECM plug. The motor turns over but I'm not getting spark, nor is power being supplied to the fuel pump, but I can hear a relay clicking on in the EFI fuse box when first powered up. I'm pretty sure the box is alive.

I'm waiting for a FTDI based serial>usb adapter so I can check in with the computer via a laptop, and know I need to tune the ECM for this motor. However, I assumed that this ECM would be plug & play since it shipped with the crate motors and that the motor would at least fire up. Could the ECM be stuck in some sort of diagnostic or pre-initialization mode? Do I need to initialize the computer by specifying the crank/cam sensors or do some calibrations? I may just have to wait until next weekend when I have the adapter and can work on this again until I have more info.

In the meantime, if any of you have any experience with this ECM or tuning one and could share your experiences and wisdom, I'd be most grateful. :prayer: The anticipation is killing me!! Also, if anyone has a base tune similar to my setup that I can start with, that'd be the bees knees. Any advice would be much appreciated! Thanks in advance.

Here's what it is:
6.1L based 426 (Indy Cyl Head shortblock)
Mopar Performance CNC ported heads w/ big valves
ported 6.1L intake manifold
SRT8 Jeep exhaust manifolds
Cam: 231/240 dur @ .05, .539/.544 lift, 113 LSA
