Electronic shift with Fast

[Larry]

With a 400 trans, I would like to have the car electronically shift 1st to 2nd gear at a desginated RPM. I would go manual for the shift from 2nd to 3rd. How would I wire it? And would I be able to overide this to go all manual at times. Thanks Larry

You can use a nitrous output to do this, but there's no way of telling it not to make the 2-3 shift. The enable wire in the nitrous control wiring could be turned off for full manual control.
