As test control, when you put old injectors in with old settings, does it start, run and idle OK?
Where do you have MAP-sensor plugged in? It needs to be between throttle-butterflies and intake-valves.
With sparks unplugged, measure MAP output-voltage when cranking for 5s. Gives us baseline number for idle.
Other thing to be extremely careful about is battery-voltage and shutdown procedures. It must have +12v and 3-sec of power after shutdown. It rewrites/saves to memory when shutting down and if it doesn't have sufficient power, memory and your maps will be corrupted.
