I have been browsing the workshop manual for a 93 Hilux / Tacoma and checked the vehicle and it has an electronic speedo. This is brilliant because I wont have to retrofit one.

The speedo just requires a 4 pulse per revolution input from the shaft.

There is a pulse output from the Danfoss VFD that is programmable. I will also be able to adjust the VFD output to compensate for the change in differential ratio.

This setup will require that I use closed loop control to have an accurate speedo.
