Shaun,
The computer would need to be Very Powerful and Fast to handle the input
stream of all
the sensors required to perform this (not cost effective today, and
would certainly need to
come from Dodge, aftermarket couldn't absorb the cost of development).
Eventually we
will get there though. While were on the subject, I would like to see
Dodge include in the
computer the capability to use a MAP (Manifold Absolute Pressure), that
would measure
positive pressure (supercharged applications), we could then change the
ignition and fuel
maps to handle almost any amount of "boost" from these devices. Ever
wonder why the
Buick GN can run and use a totally streetable "16 LBS" boost. I'll send
you e-mail about
the shop.
