If your EFI system supports Mass Air Flow fuel management, converting from Speed Density to Mass Air would eliminate the requirement you are now faced with. More significantly it would auto compensate for atmospheric change wherever you are because it measures the mass of air the engine is using to determine the correct mass of fuel to inject.

Alternatively you can retain the Speed Density fueling model and just visit your local dyno tuning shop to adjust for atmospheric change whenever you need to.
