The FIC can be a tricky devil to work with. I have a fair amout of exp. with it in conjunction with the stock 90-93 ecu.
If you are in-fact starting with a stock set-up (no boost, stock injectors) then you should be able to start with zeros in all maps and have transparent operation. If you aren't getting this far then you probably either have an interconnect problem (electrical or vac), or a load input/scale issue in the settings page.
I would suggest you start with fuel map from MAP load
Timing from MAP
MAF from MAF with 5V clamp, no scaling (percent, voltage in equals voltage out)
O2 set to percent with zeros in the map, high drive, 0 V low, 1V high
disable accel enrich with a 0 in the ~second~ (going by memory here) box
Sounds like you have tan-tops, I have seen good FIC results with an IRT of 1300, my measured values with the MS are more in the 700 range. I am able to get stable AFRs throughout my map at 1300, so start there.
Make sure you run through the RPM cal.
There are some implications with using the TPS on a manual car from 90-93, the idle switch in the TPS is 12V referenced, the FIC is designed to handle 5V, so it bonks. A resistor divider fixes this, let me know if you are going down this path.
Post back when you get to this point if you want some tuning advice.
