I can answer this one! The Corvettes didn't use a cable drive speedo(84 up). Here are your two options if you want to retain the cable driven speedo and have a VSS.........http://tpiparts.net/82_92_sensors?start=25. The first one "sensor 802" is your best option. It was originally used on police intercepter cars.
I suppose it could be programed around, as I fail to see why the computer need to know the car speed, except to lock the converter....which somehow happens too soon on my car as the computer thinks it 55 mph when actually it's only 40....
need supply your programmer with your tire diameter/rear ratio and of course o/drive ratio...

Great TPI install link
Awesome, that's sounds like exactly what I need. Hope is has the right gear-tooth count for my 3.08 rear gear.

It should give you an idea on what is invovled.

Markdtn,
What did you use for the VSS in your '69 with the 700R4? I'm doing a speed density setup (ZZ4 with a Camaro ECU) on my '70 and I'm using an '88 Vette 700R4. Did the TPI Vettes use a cable driven speedo with 4K pulse VSS (I think speed density is a 4K pulse)? If not, where did you get the VSS setup? Part number? Not trying to steal the thread but this seems to be as good a place as any to talk TPI turkey.

MAF TPI would use Painless VSS #60115
MAP TPI would use Painless VSS #60116
