Cranking but not idling

2002 Acura RSX Type S
K20A2
Wiseco 87MM 8.9 CR pistons
Skunk2 Stage 3 tuner cams
Skunk2 Ultra Street series intake manifold
Skunk2 74mm Throttle body
Deatschwerks 2200cc Injectors
Stock map sensor
Turbonetics 6468 twin scroll 3" V band
44mm Tial wastegates
Tial Q BOV
MAC boost solenoid
3 Inch straight piped turbo-back exhaust

Due to the previous owner not correctly installing piston rings I decided to rebuild the engine in my RSX. It ran and idled before. Just got everything back together and a basemap uploaded and the car will crank and run very poorly if I feather the gas constantly and will still stall after a few seconds.
I'm getting fuel pressure at the regulator, I double checked that timing is still correct, everything is connected, I'm not sure it's the basemap however I'm pretty much stuck on what else to try. I have attached the basemap and 2 datalog files of it "running" while I feather the throttle. Any help would be very much appreciated.

Does this have an idle controller?

I have the factory idle air control valve on the throttle body

It also will not stay running even with the throttle all the way open, I forgot to state that as well.

Make sure the the rotary valve in the idle controller is not stuck. Have you entered the dead times for the injectors you are using?

I will check that. Would that still prevent it from staying running even with an open throttle? The dead times on the basemap that I have seem to be consistent with injectors of the size and brand that I'm using, may need to be fine tuned but I just need it running for the time being.

It could be any number of things at this point, since it has been completely disassembled since it was last running.

Very true. I tried a different MAP sensor just because it had one that I was planning on installing after it was running anyway and it started right up (with modification to the calibration for it) Thank you for the help and quick responses though
