DAT240Z Posted November 23, 2006 Share Posted November 23, 2006 I just got my 240zt running, and notice the realy board does a lot of clicking while I'm driving. Would anyone know what would cause this, or is the clicking normal. stock turbo 370cc injector 3.0 board 3" ext. Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted November 24, 2006 Share Posted November 24, 2006 Are you running a PWM idle valve? Some of the things this could be are rather bad. If it does this at idle, I would check the voltage on the fuel pump output to be sure it's not turning the fuel pump on and off. It wouldn't be so worrisome if this is the fast idle valve it's turning on and off. Quote Link to comment Share on other sites More sharing options...
DAT240Z Posted November 24, 2006 Author Share Posted November 24, 2006 Matt, It click at idel and while I'm driving. I do not have a PWM valve. I place my hand on the three realy and found the far right relay (THE ONE NEXT TO THE 37 PIN CONNECTOR) is the one that's clicking . Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted November 25, 2006 Share Posted November 25, 2006 i have version 2.2 board and that relay is the fidle relay.on version 2.2 you use the fidle circuit for either fidle control or spark control.since i use mine for spark the relay is removed and a jumper and pull-up resistor are in the relay sockit.is relay pulling in in relation to engine speed?like the relay clicking changes with rpms?the output also has to be configured on initial set-up with the software.my fidle circuit output wire goes directly to yellow wire on zxt power transistor /coil brackit.
