problems with EFI car idle and pressure sensors

This raises an interesting point. I've data logged at about 50Hz,
and on a sharp throttle opening MAP changes almost instantly, i.e.
in about 1/25 of a second. You can't move the throttle much faster
than that.

Why would I need TPS? (Except for overrun cutoff, etc)
