Greetings,
Has anyone ever seen an
aftermarket boost controller that uses a motor of some sort to directly drive
the wastegate?
I've found a couple of
controllers that will work as absolute pressure devices (HKS EVC IV atm,
and EVC PRO), but they use a stepper motor as a variable air leak for
the normal wastegate actuator. Even this would be a step forward, but
I'd need an actuator with a light spring. Of course I can't tell how low
these controllers will regulate, since they only brag about the high end.
Anyway, something else to think
about.
Speaking of light springs
in the actuator, how light could you go and still have it work? In other
words, if there was nothing hooked up to the wastegate lever, would it have a
tendency to open, or close? I'm guessing that it would try to open, so you
need some spring pressure to hold it closed, but how much, I haven't a
clue. As usual, more questions than answers...
I'm starting to imagine a
big RC servo being controlled by some sort of electronics connected to a MAP
sensor. Hey Tracy, how about throw that into my EM-2
:-)

The end is near... uhh,
make that in sight :-)
