LG4 to TPI (maf based)...need new PROM?
Do I need a new prom going from an LG4 5speed, and using the intake/pcm from a TPI automatic car?
I figured as long as there was a VSS signal all would be well.

If it's from an '89, you'll need to at least disable VATS.
Otherwise, I'd expect it'd run well enough to be driveable. I doubt it'd be anywhere near perfect, though. So, if you want it really right, start with a manual bin, and tune the PROM yourself.
