Default Ej251 turbo questions

I'm turbocharging the ej251 in my usdm 2003 legacy gt with an auto trans, the project is already started so dont tell me not to do this lol
04wrx headers
04wrx up pipe and downpipe
04 wrx exhaust
04 wrx tdo4l
04 WRX intercooler
04 wrx aem intake and piping
Aem uego Afr gauge
Greddy profec eo1 boost controller with the LCD screen
Boost gauge(eBay)
Turbo cross member
Oil lines
Coolant lines
04 wrx injectors
04 wrx fuel pump

Now my questions are
1. I have a camcon avcs/Afr controller for an ej207, can I use this to control Afr? The harness does not match my ecu so it would need splicing.

2.i do not have a way to tune as of right now so I'll only be running about 5psi, I do not have a rrfpr, would using my wrx fpr and injectors give me the extra fuel I need or would that make my ecu freak out?

3.i have 04 STI seats and I'm curious if there's a way to hook up the heated seat features since the car has heated seats and the STI seats have the heated feature aswell.

4.i have a map based system, is there anyway to run this without a voltage clamp? My boost controller is able to adjust boost in 500pm increments.

Basically have most of it figured out but I want to know if I can run this for atleast a bit without a tune and will I be able to use the WRX injectors instead of a rising rate Fuel pressure regulator?
