Yes it will work.
I have done this a couple times.
Might run out of I/O for the stepper motor iac though.

You can set those tables up via the 4d fuel or ignition tables.  These can be found in the fuel or ignition tabs under corrections.
You would then select your auxiliary output as the table activation(whichever output is controlling the VCT).
You can then set the table axis to what you desire.  RPM vs TPS, rpm vs MAP, etc.

Warchild,
I can tell you from tons of experience with the Subaru platforms that you will not want to use the factory "A/F sensor" to tune the engine.
As Scott said, they are not super accurate any where except for 14.7:1 AFR.
But with all the experience that I have with them, they are actually better than most OEM sensors.  They will read pretty accurate down to about 12.5:1 AFR.  Just about anything richer than that and it will just peg out at 11.14:1.
If you have any common sensor I would highly recommend a quality wideband set up.  Anything in the realm of an AEM UEGO, Innovative, Link CANLambda, Motec LTC, Ecotrons ALM.
Hope this helps.

Warchild,
If you use the modelled fuel equations and have the "Fuel System Type" set to "FP Sensor" then the ecu will automatically adjust fuel injector pulse width to compensate for falling fuel pressure. 
But adding an ignition cut or boost reduction via a GP limit for large fuel pressure drops would not be a bad idea.

If you have an H pattern box, it will be a very simplistic control.  If you  wire in a clutch switch to a digital input, you can have that be the trigger for flat shift. 
You will need some kind of sensor or digital input.  In you case, clutch switch is the easiest. 

What Mapper said is spot on.  And the addition of rocker arm stoppers will just lead to even further damage.

The stock tacho on that engine is run from the factory computer not the ignition system.
So as long as the Atom is running the tacho you should be fine.
There is no need for an inductive clamp.  If the tacho doesn't work for some reason, at most you will need to purchase an MSD tach adaptor which will still be run from the Link Atom Aux out.
 
 

yes you can convert to waste spark with no issues. 
The Rb ignitor is typically a 6 channel ignitor. 
What coils are you going with?

Hey guys, 
I have used both the x series gauge and inline controller in both analog and can setups.
Both ways have been just fine. 
In the past, I have had to fudge the numbers in the aem calibration for the the ecu to match the gauge.
I know that the aem ecus have a calibration gain that you need to play with to get the ecus to match the gauge as well.
Hope this helps.
