So, I went to spray my car last night, on the way to the log cabin. I hooked up everything, got the bottle pressure to 950 psi, put in 5 gallons of 100 octane and got on the road. We had the LM-1 wideband hooked up and were doing pulls without spray to see what my AFR was like. On my pump gas tune, my AFR was low 11’s, dipping into 10.9 at one point. We then did a pull on my race gas tune (its funny back to back, its a lot different) and it stayed in the low 11’s.
I was going to spray then, but traffic was too busy, so we decided to test it on the way back home. So, when that time came, we do another pull on motor to make sure everything is right, then I flip the arm switch and go. I have it set to TPS signal WOT and RPM window 3500 - 5700 for testing. I punched it on pump gas tune, and it felt like normal. We tried another pull, and it didn’t spray.
After that, we pulled over, and I re-calibrated my TPS switch, checked the bottle pressure, and tested the window switch. Everything seemed to work fine. We got back in the car, and did a 3rd gear pull, and it spun the tires, so I assumed it worked, but when we tried again on the race gas tune and spray, it felt no different. We pulled over and the solenoids and the nozzle were both warm… it never sprayed.
I am kinda stumped right now. We tested the solenoids by putting 12V to them the other day, and it sprayed fine. A few weeks ago I tested my nitrous controller using the window switch, and it also sprayed just fine. I must have forgotten to put in a relay, or the relay went bad, after I tested the solenoids this week. So, I have a little more trouble shooting before its a go, but everything else seems to work fine. The bottle heater had it up to about 1000 psi, and no leaks anywhere.
I’m so anxious!
