Eric Lemoine Posted June 27, 2009 Report Share Posted June 27, 2009 Hi guys, Just a little information for anyone using the GM Boost Solenoid and the Link Plus G3. I've found that the higher the duty cycle, the less boost, and not the other way around. For instance, my duty cycle at low boost is 82, and that gives 8psi on a 4.7LTT. I had it at 18 and it shot to the moon. Just some random info for anyone interested. Eric Quote Link to comment Share on other sites More sharing options...
Guest Dave Posted June 28, 2009 Report Share Posted June 28, 2009 how do you have the hoses connected on the solenoid ? can you post up a picture? i would suggest that you try connecting the hoses differently and you will find it will work as per the norm I.E. higher duty cycle higher boost also what frequencu are you using Regards Dave [email protected] Quote Link to comment Share on other sites More sharing options...
Eric Lemoine Posted June 30, 2009 Author Report Share Posted June 30, 2009 I'm using a duty cycle of 25hz. Essentailly, I have the solenoid connected like this pic: http://img.villagephotos.com/p/2006-9/1210778/emamage_ultimate.jpg The pressure supply is fed into the center port, and the exit to the gates are fed from the "side" port (not the one covered in foam). It's being fed from Aux 2. I tested it by attaching a vacuum line to the entrance port of the solenoid, then went into test PWM. As I lowered the duty cycle the solenoid clicked slower and more air passed through as I manually blew through the vacuum line. That would keep the gates closed longer. As the duty cycle went up to 82, where it is now, less air blew through, and the gates open sooner. Thanks! Eric Quote Link to comment Share on other sites More sharing options...
chris briggs Posted August 17, 2009 Report Share Posted August 17, 2009 so what your saying is that the higher my duty cycle, the less boost i will have. I have it hooked up just like in the diagram you provided a link to.....I thought thats the way my boost controller was working. thanks Quote Link to comment Share on other sites More sharing options...
