Re: Controlling Turbo boost

Robert,

	There are a number of electronic boost controllers out there.  I 
haven't installed one on a car of my own, but I have seen a bunch of 
them.  The best that I can tell, is the Fuzzy Logic Boost controller by 
Greddy.  It senses the manifold pressure and RPM, and "learns" the 
resonant characteristics of your engine, so that it can maintain EXACTLY 
the preset boost level at all times.  I have heard of installations where 
the FLBC was set to 14.5psi, and through the first few runs, the boost 
spiked just a little higher than 14.5psi, but after three or four runs, 
the boost would hit 14.5psi and stay there right to the redline!  It 
includes a digital boost gauge that reads to a tenth of a psi.  It also 
costs almost $800.00, so I guess it had better toast marshmallows too.

	I think that the new HKS EVC III (?) has fuzzy logic built in at 
a much lower price.
