1992 (JDM FD) RX7 Engine Crank No Start

I recently picked up a single turbo 92 RHD FD RX7 with refreshed rotors and rotor housing that will not start.
The engine has good compression and I got a few puffs after putting the coil dwells in the right order.
As of now, there is no intercooler piping, coolant, air pump delete, power steering delete, (all to be done, but just trying to hear the engine run for a couple seconds).

I believe the issue is to do with me and the AEM Series 1 ECU it came with, the AEMpro software is outdated and since the AEM forums are
no longer available, I find it difficult to approach the software. I figure the missing parts and fluids may inhibit starting, though I think its more likely that
if my injectors and TDC offset were calibrated I should be able to hear it sputter.

From a mechanical perspective, here's what is going on with everything to do with ignition:
-Stock primary injectors
-1600CC xl3e-c9a secondary injectors
-KGParts Fuel Rail
-Denso S-31A Spark Plugs
-TDC was found with the help of RADx7's video, find apex seal in center of T2 (closest to firewall), mark crank pulley, find apex seal in center of L2, mark crank pulley, and the midpoint is TDC.

The coils are correctly ordered T1 to T1, L1 to L1, etc.
There is spark in each of the spark plugs.
There is fuel getting into the engine.
And there is air

Is anyone able to give me a run through the AEMPro software? I'm a computer engineering student and will be able to grasp
the program but I'm looking for a starting point.

How do I set TDC with the ECU? Where is the timing lock?
Is sending a new calibration file to the ECU the same thing as simply modifiying a value and pressing enter?
Is 1800.V1.19.cal for single turbo setups?

I've attached the .cal file that was in the ECU when I bought it, if anyone is willing to take a look.

I have a lot to learn and any help is appreciated.

what is your base fuel pressure set to?

if the fuel pump is working, base pressure is set correctly, primary injectors are firing, coils are sparking, both cas sensors are plugged in, map is scaled to the map sensor being used, tps is plugged in, water and air temp sensors are registering then it will start. this statement is assuming each item is hooked up correctly and is functioning as it should. use the software to verify the data from each sensor. i have never used the v1 software but i imagine it has some monitoring functions to show parameters of various sensors and there operation.

the missing items wont inhibit the car from starting although i would advise removing the tape from the turbo outlet. i don't know what will happen if that is blocked when the turbo spinning but i imagine it wouldn't be great to choke it like that. as far as confirming the write function of changes to the map, you can do a "read all" or something to pull the map and see if it matches what you input. there should be some sort of confirmation of a write function being executed successfully though.

if you want to use your status as a student in the computer field as basis or gauge for competency then you don't require any kind of instruction on how to use the software. read the labels of the functions in the various screens and menus and come to a logical conclusion. ultimately, as a non tuner, you shouldn't be in the ecu doing anything at all. it would be in your best interest to have someone who is familiar with tuning and tuning softwares to handle this part.
