veck: it is capped off, since there is no need to route it anywhere. i also plugged the old air inlet (where the bleeder used to bleed to) which is on the intake pipe.

ps. recently remapped my boost map with ECU values in all but the 100% column. this way the ecu's part throttle tapering of boost is in effect. so far, so good:the fbc algorhythm seems to be handling the GM solenoid well.

in other words, you could use the above topology, along with a tps switch (as seen on my website) and DPDT relay, the stock ECU and an MBC (to "clamp" the max value) to the same effect. the DPDT relay would be energized at some value of throttle position sensor voltage, and it would:

1) disconnect the the GM solenoid from the ECU
2) switch IN a suitable "dummy" resistor (so as to avoid the CEL for a BCS failure)
3) put a steady 12vdc across the GM solenoid.

voila--MBC boost levels and response with full part throttle taper. i'll get around to trying this out sooner or later, in order to free up the UTEC boost solenoid driver circuit.
