Dual Stage 2 MSD WS's 2 Activations Switches All Done!
 
1 Attachment(s)
All done but not working right. :eyes: i have everything set up exactly like the diagram but for some reason my relay is rapidly pulsing when it send power to the solenoid. if i bypass the FPSS or the WS, the relay will open correctly and provide 12+ volts to my solenoids.... but when both FPSS and WS are used inline to provide a ground to the relay, the relay will only send 5-6 volts to my solenoids. solenoid seems to spray fine with the 5-6 volts but i'm concerned about the relay making the rapid pulsing noise and wear on the solenoid. what do you think?

Try by passing the FPSS with a jump wire.

here's the one I used on my dual stage, maybe some insight. i didn'y really go over your diagram, but sounds off hand like FPSS, or maybe WS?

just hearing MSD window switches and pulsing reminds me of the exact same thing that my MSD digital switch did. my dyno graph looked like a lie detector test :lol:

i got the relay to work right as far as relay staying completely open now. i haven't tested the setup yet because i'm out out of nawz. hehe. got a 100 lbs coming tomorrow :) .
Dan from Dynotune suspected that it was the FPSS and was right so far because i got the relay to send out 14 volts to the solenoid and the relay stays open. i had to back off on the FPSS 1/4 turn. i hope that's not a sign that my fuel pressure is low. :eyes:
i'm using the FPSS from my 5177 kit and from the reading on here, it's set to 35 psi as default. i don't have a FP gauge. anyone want to give me 2 cents?

come to think of it, there were several times that i could hear my relays making the rapid open and close sound with the old setup and caused afr to not stay constant, it would decline then slightly incline then decline when on nitrous. on NA i would get a good looking decline and flatten out. i thought it was my tune but maybe it was the relay not powering the solenoids correctly.
