Ron this is the word your looking for "stoichiometric"
and yes the open or closed can be turned
on or off with a laptop.. I'm still learning the
Holley multipoint system I bought but just from reading
it has WAY MORE than I need at this time but will
allow me to add things down the road..it will control
boost or nitrous and many other functions.. turn on
the fans, control timing with and without boost...
like I said... I'm still learning.. I'll take it out
in the spring and start to learn what I can do
