I got the HSW wet kit in and wired up. I have the microEDGE and a FPSS, plus a LNC-002 to pull timing. I start it up & let it idle, I check out the bottle heater and it works well. I hit the purge switch & I hear the noid click so that's okay. Than I hit the arm switch & I hear a click & the car stumbles ready to stall WTF? . All looks well from my guages, no smoke, no flames, no codes. I'm thinking I wired something wrong for the arming noid &/or its a FPSS issue? I disconect the wire from the FPSS that I have going to the Noid relay #85 and just leave the ground wire intact. I go to start and no problem? This is how I wired it up . I have the Noids tied together going into thier relay on #87 along with orange wire for the LNC -002. The grounds from the noids run in conjunction with the FPSS to a good ground source, the #86 relay terminal has the green microedge wire & a switch panal wire tied in. I have the tan microEDGE wire going into # 85 & the FPSS wire tied into that also. This sound right?? BTW I didn't touch the adjuster on the FPSS, I bought it new from Nitrous outlet.

 

Also would a FPSS cause a stumble, I thought it would just deactivate the noids from spraying. I never have issues withe the car and the fuel pump is running 60psi.

 

so when you armed the system the noids activated? Recheck all wireing for the 100th time, and make sure your settings are what you have them at in your other post. Take the fpss out of the equation and try it...sometimes i heard those are more trouble than theyre worth

 

sounds like the noids came on when the you flipped the arm switch and fuel started spray.

 

89 ROC-Z I reprogrammed the microEDGE & did the selenoid check & heard the click at WOT with the key set at accessory. I rechecked my wiring for the fuel/ Nitrous noid & all looked good.
Camscam 02 Thats what I was thinking also. but why it didn't do it with the FPSS disconected puzzles me.
I opened a ticket with HSW & await thier answer.

 

Fuel Noid clicked & sprays fuel when the switch is armed and FPSS attached . Disconected fpss and all is well? I have the fpss to pin # 85 on the relay along with the tan wire from the microegde.
I did a test on the microedge with a wot and all worked as supposed to, sprayed displayed in microegge & I heard the click. I just did it for a second. This was done with the FPSS disconnected.

 

HSW support set me right. I wired the FPSS incorrectly. I now run the tan wire off the microEdge to the FPSS and run the other wire from the FPSS to the #85 relay for the spray selenoids. It works right now.
Thanks for all the help.
