Does anyone know how this discussion applies, when using an electronic boost controller? I've just picked up an AVC-R as part of my upcomming install, and from the instructions, the setup is :
- Pressure tap from charge pipe, i.e. compressor out, through bleed-off solenoid to wastegate actuator.
- Pressure tap from manifold after throttle body, to electronic sender sending back to the EBC.

So the EBC is controlling what portion of the charge pipe boost is passed to the wastegate actuator, in order to achieve a desired result at the manifold. I'm happy with that. But what about when the throttle is only slightly open, and the manifold is under vacuum or low boost? The bleed solenoid works such that the EBC could feasibly not let any charge pressure through to the wastegate actuator, meaning the turbo would make as much pressure at the charge pipe as possible, a la IowaRS's example.

I guess that EBCs must use some algorithm for this, but it would be nice to know what it is.....

Thanks,
Mark.
