This excel sheet was created by me and my friends to allow for the proper determination of shift points. I will be posting a report of how the calculations are made in the coming days. In order to use the sheet you must input your torque curve. You have 15 cells to use you can use some or all of them and change the RPMs as you see fit. You much also input tire diameter, tranmission ratios and final drive ratio. Simply click the large run button and the shift points will automatically update. Macros will need to be enabled.
