I have a 1F.xdf file that I found somewhere (probably on moates.net).
I can email a copy if you pm me with an address.
Here's a link:

I just looked at the xdf. I see what you mean. It is pretty limited.
Normally there are single fire and double fire injector constants where you can set the #/hr to match the injector.
I'll poke around in a $1f bin file that I have, to see if I can find the correct addresses for the injector constants.
If I can find 'em, I'll update the xdf and send a copy.
Update:
From what I can see in the $1F bin that I have, they should be starting at address 0x038F (following the stoichiometric value and table look up multiplyer value)
Hovever the values don't show the expected doubling pattern or scaling that exists in the later masks (32 and 32B etc.), but this could be different due to the different loop time, so I can't be certain of how they are scaled. Maybe somebody has a $1F hac and can chime in, or provide an improved xdf.
Here are the hex values that I see at these addresses which I suspect are the injector constants:
0x038F: DD F0
0x0391: F5 00
If these are correct (which is a big if!) you could try scaling them, but if they follow the same pattern as the later bins you will need to reduce each value proportionally to increase the constant the same proportional amount.
In the event that you make changes with a hex editor, be sure to update the checksum. I don't know if the TunerProRT (advanced) hex editor is doing this automatically. Opening and saving the file should update the checksum, though.
