Well I'd like to see something that one way or another could use either 
(as in both) points
or pickup coil/module combo? for triggering to expand possible market 
exponentially. 
  To me the purpose of the pc interface is so that one can compare
results and 
other data in reference to fuel/ign settings. Personally which way I go
with
fuel and ign depends on MAP, rpm, but others may have other ideas. The
point is 
that one way or another access is needed to all info preferably on the
same screen.
If not that at least the ability to snoop around for data at a
particular point
and then set fuel and ign from that data, maybe a log of data from last
setting
for comparison purposes?

Keep me posted.
