I think it can be done with EFI Live. But on my car I am using a Compushift controller so I decided to use a Dakota Digital SGI-5c speedo signal calibrator.

This would work for you too....

You need to tune it for a 40 tooth reluctor wheel.

And the rear gear, tire size. Make sure it's plugged into the rear sensor.
