I'm planning to purchase Genboard and learn from basics. Here what I can gather so far:

Volvo B5234T3 2003
5 Cylinder inline
5 injectors Low-Z

I think I need:

1. Boost control valve
2. Injector FETS
3. WBO2 Heater fet
4. Boost MAP and MAT from VEMS VW number is 038906051
5. Ignition Driver IGBT? 8 or 6+2
6. Stepper motor/IAC from volvo 850 - should i go with this?
7. low voltage flyback.
8. external MAP sensor jumper
9. trigger selection jumper
10. logic level ignition output jumper
11. PS2 interface
12. LCD interface

According to the specs we could find (ME7) for your engine Volvo B5234T3 2003 it has:

5 smart coils.
5 injectors (Low-Z)
VR crank sensor
HALL cam sensor
2 knock sensors
Boost and VVTI solenoid

Using those specs and the list you posted above (ps2 option is not practical on your setup instead wheelspeed input is much more versatile) we would recommend:

Vems V3 Assembled ecu from: http://shop.vems.hu/catalog/vems-p-48.html, with the following options:
- 1-wire interface no
- EGT input 1
- Flyback LowZ active flyback 8ch
- ignition driver 2+6
- Knock input channels 2
- LCD connection yes
- MAP connection offboard(electronic)
- mounting-style flanged case
- primary_trigger EC36/27 VR
- secondary_trigger HALL
- Service normal
- withSDcard no

Wideband sensor with connector: https://shop.vems.hu/catalog/wideband-sensor-p-37.html
VW MAP sensor 038906051: https://shop.vems.hu/catalog/boost-p-80.html

Free inputs for extra function activation are standard available on the ecu, one of these can be utilized to handle the Input to retard timing from TCU

A stepper chip for driving the Volvo 850 idle valve is also a standard feature of the v3 ecu.
