To adjust the amount of steam output for different locomotive states using the mxion 4701 High Power Pulsed Steamer without Logic Control, you can follow the steps outlined in the user manual:

1. Setting Steam Volume Levels:

   - CV40: Adjusts the overall steam volume level.

   - CV41: Sets the amount of steam for acceleration.

   - CV42: Determines the amount of steam during driving.

   - CV43: Controls the amount of steam while rolling.

2. Clock Register Control:

   - CV44: Manages the clock register control, where 0 means every clock, 1 means every 2nd clock, and so on.

3. Steam Starting and Output Cycle Time:

   - CV45: Adjusts the amount of steam during starting (100ms / value).

   - CV46: Sets the steam output cycle time for steam locomotives (10ms / value).

4. Connection to DRIVE Decoder:

   - Connect the pulsed evaporator to the DRIVE decoder using DEC +, DEC-, and two arbitrary function outputs (e.g., A7 and A8).

   - Assign A7 and A8 to the same function key (CV180 + CV190).

   - Set CV193 to 22 for steam or 23 for diesel to activate the special function pulsed evaporator control.

   - Configure CV115 and CV116 based on clock generator or simulation usage.

5. Connection to GVS:

   - Set the steam volume levels and other parameters (CV40-CV46) as mentioned above.

   - CV48 can be used for clock simulation correction.

   - The GVS automatically recognizes an external clock or can be specified via CV49.

By adjusting these parameters in accordance with the user manual, you can customize the steam output of the mxion 4701 High Power Pulsed Steamer for different locomotive states to enhance your model train experience.
