FAST speedo question
I am installing a XFI on my 94 TA to eliminate the opti. Since the FAST unit does not have provisions to run a speedometer and I want to completely take out the stock pcm, does anyone know how to run the VSS to the XFI or the gauge so that the speedo will work?

FAST has a VSS harness for the XFI you can order seperatley. I kust finished installing the XFI/XIM setup on my 00 Z28. I am dumping all the factory guages in favor of the digital touch screen dash.

There is a 4 pin connector near the ecu labeled VSS. You will need to run the VSS to pins A & C and jumper pin B to Pin D. You will set the parmeters at: View/System Configuration/Sensor Calibration/Rate Sensor Callibration. this "should" allow the MPH to be displayed on the XFI. It won't help with the factory speedo. Wickedred has the right idea going to the Touch Screen dash.
