My Zex kit is not spraying correctly. While troubleshooting the issue I had a friend rev the car to 5k and the Nitrous did not engage nor did any fuel spray. The Window switch is set to engage at 3k. After a few seconds of running the car at idle it started to spray both fuel and NO. It should have not done this so I disarmed it. When I rearmed it it started to spary while idling again. Not sure why it is doing this. I checked all my connections and tried to reset the NMU to correctly register the WOT switch. While doing this it started spaying at idle again and does not stop until I turn the system off. I checked all my grounds and switch connections and everything looks good. I have had this system connected and functional for 6 months. Are the Selnoids going out (NMU) or do I have a wiring issue?
