I compared the ISCV tables to my stock 00008 and the AC on was much higher. I, in turn, raised only the last 2 rows to allow my car not to stall with the AC on.
Wait, I also raised the last row 7s to 10. Revolver cams need a little more air.

I reenabled FEA bit 14 (MAP vs Baro) and also reenabled FDA bit 15 (Coolant temp below reg) I am waiting on the car to cool down, I had to adjust the injector latencies a little bit again today when I got off work... car feels like it definitely drives better...

Still have cold start problems after STFT kicks in it still pegs +25. Also something I may have forgetten to mention...at the same time the engine RPM jumps to 2500 for about 20 seconds until the STFT goes back to about -1... I am at a loss...

Doing the changes I mentioned earlier....my cold idle issue is SOLVED....hopefully for good this time.
I have no EGR junk or EVAP junk in the car either. It idles smooth and holds exactly what my Idle tables state. It no longer goes lean when attempting to drive with the engine cold.
Freddie....your fuel trims are still learning. Give it a few days of continued driving and see if the issue is still there. If it is, I would assume that your injectors and MAF may need scaling.
What injectors and intake system are you running?
These are my settings....
Table
EGR System Enable/Disable....changed from 1 to 0
Periphery FAA bit 11 (Disable EGR . Enable Ign Adv) set to stock setting = 0
Periphery FAA bit 10 (Timing Knockdown on Light Acceleration and less than <3000) set to = 0
Periphery FAA bit 9 (enable warmup ign retard) set to stock setting = 1
Periphery FCA bit 15 (P0443, P0446, P0403, P0243, P0090, P2263) set to = 0
Periphery FCA bit 14 (P0450, P0451, P0452, P0453 Evap) set to = 0
Periphery FCA bit 13 (P0441, P0442 Evap) set to = 0
Periphery FCA bit 10 (P1400 MAP sensor) set to = 0
Periphery FCA bit 9 (P0401 EGR Test) set to = 0
Periphery FEA bit 14 (P0069 MAP vs Baro) set to stock setting = 1
These are all that pertain to EVAP, EGR and cold idle issues.
Others people....please give these settings a test and get back with us. The more that confirm the results the better.

ALSO....
This table....for v7 96500006 versions...
<table name="Ignition Unknown Map (warm-up?)" category="Timing" address="61c9" type="3D" swapxy="true" scaling="Timing">
<table name="Load" address="6910" type="X Axis" elements="19" scaling="Load"/>
<table name ="RPM" address="68de" type="Y Axis" elements="20" scaling="RPM"/>
</table>
will show up as a timing table with a big hole in the cold cruise area.
All I did was change the stock +5* timing areas in the idle area to my current cam timing setting of +11*. I left the hole alone other than changing the +5s to +11. It seemed to help idle considerably....the car idles much smoother and timing does not fluctuate near as much as it used to.

Paul I changed all of that already, except I have FAA bit 9 disabled...
As for injectors I have FIC 750s and for the intake I have one that R/TErnie and I fabbed up for use with the Synapse Synchronic...
Also are you doing Mrfreds EGR routine disable?
I am rescaling the injectors as we speak...

That makes me wonder if you might have an exhaust leak. OR, another possibility is that your front O2 is on the way out.
When your O2 sensor is warm and starts working is when your conditions starts?
Think about it. When you run full time open loop, your issue isn't there.

I was reading a few other threads about the Bosch replacements doing the same thing, so I just ordered an OEM replacement from oxygensensors.com should be here next week... so we will see... hopefully this solves my issue...

Hit up your local mitsu dealer....They have used O2 sensors laying around from other Mitsu cars. Ask them to give you one....then just splice it in to your current harness.....FREE. Then you will know for sure if the sensor is bad. I did this when my rear one went out. The replacement has worked great for a couple years now.

Well I am 99% sure it was the O2 sensor... I still had the old O2 sensor laying around and only replaced it due to a CEL. I soldered the old sensor back in and viola... no more uber rich start up issues. Just have to redo my scaling and latency... I am gonna wait until the new sensor gets here to do that though...

Anyone else following this thread try my setting? I would like to confirm the settings are correct on several cars before I go in the EGR removal thread and post the reuslts.
Thanks everyone.
Paul

You made me burn a bit of time over the weekend on this one. 
This was the only difference between your configuration and mine that I could see, and I wanted to dig into that bit of code to see what was going on.
So, I started a thread about periphery FEA (and others), after being unable to locate any usage other than bit 4. Turns out, there isn't any, at least not on 96530006 (it does get used on 88590015). So, you could flip that bit to whatever you want; it's not going to get referenced.
Anyway, just wanted to point this out; it's one less variable to worry about, at least on VIII ROMs.
----
Regarding the settings themselves: except for the FEA setting, we're identical. I flashed an update to that oddball timing map this morning to see if a little extra timing (I'm on E-85) would help the situation, but unfortunately (!?) it's too warm right now to know if I'm seeing anything but placebo effect.
