Thought I would report back to this and finalise it all. Sock's diagram helped me put the nail in the coffin with the crank sensor. For the first week, the car would randomly misfire; this was due to the 22-pin connector coming ever so loose of its own accord. I solved this by placing the bypass harness in an upright position and it has since (touch wood) been fine for 2 months without any problems.
The car is running perfect with the FIC connected and maps all zeroed out (injector pulse width also needs to be at 0, not 486). Only issue was a hunting idle (guessing the FIC still wants the MAP hooked up). I haven't run the vac line because I'm lazy - despite having it ready. The wideband is still sitting in the box too. Oh, the woes of procrastination.
Attached is the wiring I used for the FIC on a MAP based Beta 1 UK Tiburon/Coupe. Wire the crank sensor like Sock's diagram above; just use pins 33 and 34 instead of 16 and 43, respectively. Job done.
