Just had an idea regarding VNT control which may be of interest to some people.
Basically, as we know, there's two ways of controlling VNT. Mechanical or electrical. Now Ruan has gone for a complicated microprocessor setup but i've had a genius idea and I want to see if it'll work first. So yeh Ruan, pipe up!
Having thought about aftermarket rev counters etc, I'm thinking we could use the alternator W terminal to control the vanes on a VNT blower too. It's an output directly related to RPM's, all we'd need is something to invert the power output and feed that to a stepper motor like in a rev counter.
Hey ho, adjustable boost directly linked to RPM.
Can't believe noone else has thought of this yet
What I want to know is
a. feasible?
b. what can be used to invert the current?
Ruan.. i'm looking at you
