Using the Criterion for Maintaining the Same Horsepower Before and After Shift:

Finding Best Shift Placement Points For Ratio 3.06 to 1.83: Error: Search outside range - need more RPM range in HP table! Finding Best Shift Placement Points For Ratio 1.83 to 1.29: Error: Search outside range - need more RPM range in HP table! Finding Best Shift Placement Points For Ratio 1.29 to 0.98: Error: Search outside range - need more RPM range in HP table!

Maximumizing the Area Under the Horsepower Curve:

Finding Best Shift Placement Points For Ratio 3.06 to 1.83:

  • Found optimum shift RPM at 0, which achieves maximum area under horsepower curve, and lowers the RPM to 0 after shift
  • Finding Best Shift Placement Points For Ratio 1.83 to 1.29:

  • Found optimum shift RPM at 4993, which achieves maximum area under horsepower curve, and lowers the RPM to 3520 after shift
  • Finding Best Shift Placement Points For Ratio 1.29 to 0.98:

  • Found optimum shift RPM at 4995, which achieves maximum area under horsepower curve, and lowers the RPM to 3795 after shift
