Disconnecting Boost Solenoid

Disconnecting Boost Solenoid
Does anyone know what effect it would have on the running of the car if I was running a dawes device and completely disconnected the boost solenoid...ie does this have any effect apart from controlling the maximum boost which is what the dawes will now be doing?

Don't completely disconnet (the connector), leave it connected otherwise you'll throw up a CEL. Just disconnect the 2 pipes at the wastegate and turbo nipple end and blank them off.
The other thing you have to bear in mind is if the ECU goes in 'limp home' mode, where something is amiss and the ECU limits boost to 0.5 bar or so. Of course the Dawes will override this.

Ok, so are you saying that as long as I don't disconnect the electrical connector (2 wires), it doesnt matter if I disconnect the vacuum pipes so that no vacuum goes through the solenoid, only through the dawes?

The reason I did this is because the car was overboosting massively before on the standard setup so assumed the solenoid wasnt working properly.
I wanted to know if there would be any negative effects by me doing the above?

None of those, well - not that end anyway. remove the pipes at the turbo and wastegate, not the BCS. Then blank them off. This guarentees when you come to reuse the BCS at a later date (and you will ) no crap has got into it etc.

Bugger another post in front of mine
In that case, you have long lengths of pipework, including a restrictor between the turbo , Dawes and wastegate. If it works, well then fine.
But I wouldn't do it that way, I'd do it the way I described earlier, keeping pipe lengths to a minimum.

Brake cleaner down all the pipes, and an ECU reset via the plugs under the steering column. This pulses the BCS hence the cleaner gets put through it.
