99 Swap Into 92 Cold Start/Idle Struggle Into No Start
Have spent the last few weeks searching through the pages and reading and adjusting the tune for my 99 into 92 Swap. From the Noob intro to spending hours searching threads trying to find others with similar issues but am continuing to find myself running into the same problems, was hoping the megasquirt experts might be able to lend a hand and point me in the right direction.
A little background on the current set up:
-99 Motor
-TrackSpeed Toyota COP
-Skunk2 Intake Manifold
-Skunk2 Throttle Body
-99 TPS and IAC
-MAF deleted
-AEM wideband
-92 Body and Harness
9093MSPNP
Spark has been tested and test firing Coil A ignites 1/4 and firing coil B ignites 2/3, all injectors are also firing.
Previously was able to hold enough throttle to keep running and set fixed timing to 10* prior to using table.
After changing so many settings in an effort to get it to run my mind was spinning, I decided it was best to take it back and reset it to the 90-93 basemap, adjusting VE, AFR, and Ignition table to reflect the 96 Basemap and adjusting cranking dwell to 3.5 to take into account the COP system. However, the motor now simply just cranks and will not start. There has to be something I'm missing here. I've calibrated TPS, AFR, and the GM Sensors, fuel pump does kick on.
I've attached the last log of cranking and current tune. Any suggestions/ideas would greatly be appreciated it. I'm banging my head against the wall here.

Quick update to this, was able to reset the map again, created a new project and can get the car to run if I hold the throttle down some.
During this time I am testing the IAC and it is having zero effect on the RPM whatsoever. Adjusted frequency, to to 279Hz, FIDLE, Valve Mode: Inverted and getting zero effect during test mode in TS.
So it appears that I am facing an IAC issue with it not opening at all. Unit is a MSPNP2 for a 9093.
