Hmm... Scott is probably stuck in nineties. :) We do not even need a MAP
sensor
for TB conversion. The engine load is only measured by TB sensor. TB sensor
is
usually used for acceleration enrichment, but when doing a TB conversion it
has
to be used for both. As you said that there's no place to connect a MAP
sensor
and even if you run a separate vacuum wire from each runner then you get a
MAP
pressure that is so jumpy that you can't map nothing with it so TB sensing
is the
only way to do it right. At least my system is set up like that and it
works.

Lauri!
