Guest |273| Posted February 18, 2009 Report Share Posted February 18, 2009 I was looking for information on Boost solenoids that work well with ViPec I mainly use the GM ones but also got one made by Apexi There is nothing on http://www.vi-pec.com/page_files/control_valves.htm and I was wondering if GM Typhoon 3-Port Boost Controller Solenoid or Apexi ones are OK to use Thanks Greg Quote Link to comment Share on other sites More sharing options...
rayhall Posted February 18, 2009 Report Share Posted February 18, 2009 Greg, I will update the Vipec control valves page. The "Vipec" boost valves are the MAC valves that a lot of companies use. You can use any two wire boost control valve. The MAC valves are three port. Quote Link to comment Share on other sites More sharing options...
Guest |273| Posted February 18, 2009 Report Share Posted February 18, 2009 Thanks I think these are the blue/black ones, right? Quote Link to comment Share on other sites More sharing options...
rayhall Posted February 18, 2009 Report Share Posted February 18, 2009 Yes they are blue and black. Here is what they look like. Quote Link to comment Share on other sites More sharing options...
Guest |204| Posted April 15, 2009 Report Share Posted April 15, 2009 Is it normal for these solenoids to give quite a wavy boost curve? I think one comment on my boost curve was that the solenoid was "lazy" (too slow to react or something) Quote Link to comment Share on other sites More sharing options...
rayhall Posted April 15, 2009 Report Share Posted April 15, 2009 Jay, As the boost control is open loop there is noting for the ECU to react too, as it just sets the value duty to the value you have in the boost table. If you boost is moving around it is for some other reason. Quote Link to comment Share on other sites More sharing options...
Guest |202| Posted May 5, 2009 Report Share Posted May 5, 2009 Hi Ray, what frequency do you suggest we use when tuning these solenoids? Quote Link to comment Share on other sites More sharing options...
Guest |273| Posted May 6, 2009 Report Share Posted May 6, 2009 I run mine at 20 Seems OK Greg Quote Link to comment Share on other sites More sharing options...
rayhall Posted May 6, 2009 Report Share Posted May 6, 2009 Yes 20 Hz is recommeded. The valve will not work much over 40 Hz. Quote Link to comment Share on other sites More sharing options...
