hodge Posted June 14, 2009 Share Posted June 14, 2009 Hi Guys Ive followed the diagram below to plum it in (cheers Kev.O) but reading the text has confused me a little. If I interprate it correctly if the controller is set at o% or turned off the turbo will run at maximum boost. If I want to run it on the wastegate spring I must set it at 100%. This is reverse to an internal wastegate. I just thought id get some clarity for you guys before I set it up. Thanks in advance John Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted June 15, 2009 Share Posted June 15, 2009 Can't see the diagram, too small, but normally there is a setting for external and internal waste gates in the setup menu of most boost controllers, which have you got? You should be able to set it to off, or just dial in 0% which should mean that the controller is having no effect. Quote Link to comment Share on other sites More sharing options...
paul mac Posted June 15, 2009 Share Posted June 15, 2009 what kind of controller is it ? Quote Link to comment Share on other sites More sharing options...
hodge Posted June 15, 2009 Author Share Posted June 15, 2009 its a greddy E01. Quote Link to comment Share on other sites More sharing options...
paul mac Posted June 15, 2009 Share Posted June 15, 2009 its a greddy E01. thats me out then as i'm still on the ye oldy greddy BC Quote Link to comment Share on other sites More sharing options...
bondango Posted June 15, 2009 Share Posted June 15, 2009 For an external wastegate, On the Boost solenoid itself use ports labeled COM and NC NC is your pressure source hose (usually Tee'd with hose from side of gate) COM is the hose to the bottom of the gate Prolly easier setting up in automode which should be in the manual Marty Quote Link to comment Share on other sites More sharing options...
hodge Posted June 15, 2009 Author Share Posted June 15, 2009 ive dun that but for some reason when the controller is set to off it still boosts above the wastegate spring pressure which is 0.8bar. Any ideas. Quote Link to comment Share on other sites More sharing options...

bondango Posted June 15, 2009 Share Posted June 15, 2009 have you tried just running without boost controller i.e. boost source straight too side port on gate only, to make sure it holds at 0.8bar and not above that? Quote Link to comment Share on other sites More sharing options...
bondango Posted June 15, 2009 Share Posted June 15, 2009 Here you go: Thats Diagram uses a simple 2 port Solenoid which is a NO (Normally open) Port hence needing 100% duty to see no effect on an external gate. Most boost controllers use a 3 port solenoid which also have a NC(normally closed) Port which works in reverse i.e. 0% duty equals no effect, specifically for external gates.

Hmm, thats odd, my Blitz BC uses the same diagram yet seems to work normally, IE 0 dc = no effect, but i do see what you mean. Quote Link to comment Share on other sites More sharing options...
bondango Posted June 16, 2009 Share Posted June 16, 2009 IIRC some controllers and also ECU's have an internal software setting for the wastegate Type i.e normal actuator/flap and External gate. these usually use a 2 port solenoid. The other use a 3 port to differntiate between normal and external gates. Ive attached both setups for the Profec E01 I would want to check for boost creep and other issues 1st by just running the wastegate and no boost controller plumbed in Marty Ps small typeo in the greddy distructions...they mention CN instead of NC Quote Link to comment Share on other sites More sharing options...
hodge Posted June 16, 2009 Author Share Posted June 16, 2009 ive ran it with no boost controller and it runs fine at .8 bar with no boost creep at all. So have i plummed it in wrong going by the diagram i posted as my solnoid has 3 posts. Im using the nc and com ports. Quote Link to comment Share on other sites More sharing options...
