Don't know if you're running turbo injectors or stock, but:

280Z stock injectors are 188cc units
280ZX Turbo stock injectors are 265cc units

 

If you're running turbo injectors, you'll probably need to put in 70% of the RPM Fuel values, ie: instead of RPM fuel = 150, it should be 106.

I would use the Toyota 2.8 N/A RPM fuel values x 70% and then ensure the MAP Fuel values match the chart at the bottom of the sample map page.  Once you have it set up, use the knob to subtract fuel until you aren't too rich.  Start at maybe -5%.  If that's better, take 5% off of all of your RPM fuel values only.  

Make sure that your water temp values are at 0 at normal operating temperature.  Make sure that your ET reads the water temp correctly, ie 158*.
