Good day guys... hoping someone can help.

I'm looking for a "Gear Shift Optimizer Calculator" that can account for two different final drives...
My go-to was always http://glennmessersmith.com/shiftpt.html

The calculator worked well for my needs, but I'm trying to optimize shift points for a 2015 Huracan and the calculator doesn't allow for two different final drives.
Right now I'm having to run the calculator twice with the different final drives and then splice the data together. This is cumbersome.

A link to a different calculator that allows for different final drives for each gear would be greatly appreciated.
Thanks in advance if someone knows of one and can send me a link!
