how to use module manager to create a duplicate but modied part

[starman2022]

I've learned about MM and have been patching components as needed.   I'd like to duplicate and change existing parts without making copies of the config file. 

For example, to edit the existing IRSU,  

I have    @PART[ISRU]:Final {    @MODULE[ModuleResourceConverter],0    {    .... }   }

But I still have only one IRSU.  I'd like to start with the IRSU, and then make a "super IRSU" part without duplicating or editing the existing IRSU.cfg file.

Running experiments is very slow as make a change, then load the game to see the effect or look at the .log files.  Is there a way to run the MM and look at its effective output?  I C, there is a way to run the C preprocessor and see the effective .h files..

TIA

I know I'm necroposting, but this thread came on the very top while I was goggling for the same thing (I'm getting old, hehe). So I decided to post an answer here so anyone getting here the same way will have the answer available:

What you want is a MM patch like this:

+PART[ISRU] 
{
  @name = IRSU_10x
  @MODULE[ModuleResourceConverter],0
  {   
    @OUTPUT_RESOURCE,0 
    {
		@Ratio = 444.0
    }
  }
}

This will copy the current ISRU part (the "+" thing), then will change it's name to IRSU_10x, then will edit the conversion ratio to 444.0 (10 times the original value, IIRC).

Keep in mind: you just created a new part, and any savegame you use it will be screwed if you delete the patch later.

I suggest you save this patch on a file called ISRU_10x.cfg, and to place this file on a directory called __LOCAL on your GameData, so you will be able to keep track of it without risking getting it deleted by accident while updating things.

<Your_KSP_Root>/GameData/__LOCAL/ISRU_10x.cfg

Uh… let's pretend I didn't edited anything, ok? :)
