Well to start off, you have at least listed that the unit is an MS1 processor on a V3 board - you have a decent enough starting platform for things to be fairly easy for you but first you need to answer a couple of questions....
Year of vehicle - 94... Good
Turbo or Na? - Intended turbo....Good
Do you need electronic boost control or intend on using only the wastegate...?
Original 94 engine or a later model engine with VICS or VVT.....?
Low impedance or high impedance injectors....?
Do you want to run batch or sequential injection...?
Can you solder or read an electrical schematic...?
Answer these questions at the very least and provide pictures of the board (both sides clearly showing where any wires go). Many V3 boards or being used on miata's currently and I'm sure we could walk you through it, but be forewarned it is easier to understand how the entire system works and how to troubleshoot it if you take the time to learn how each little component adds to the big picture.
Oh, and MS1 will get the job done but MS2 is much more powerful - plus if you utilize the factory ecu connector you aren't limited to only 4 additional output pins on the DB37 (x11-x14). I'm really liking the EGO resolution on my MS2
