Made a test light panel to test the solenoid function without triggering the solenoids. Blue is nitrous and red is fuel. Simply unplug the solenoids (I used GM style Weather Pack connectors) and plug in the test lights and the controller triggers these same as it would the solenoids.
Makes it easy to see if the controller is firing and modulating the solenoids as I programmed it to. You can see the lights blink as the controller modulates the opening and closing of each solenoid 18 times a second during the ramp and then steady on once at 100%.
Made the bracket so it fits under the lip of the air cleaner so I can mount it where I can see the lights while driving and I can test drive the system without spraying nitrous and fuel just to make sure everything acts as it should before running the system "hot".
I put on the mufflers and street tires (my street tires are 16" wide DOT drag radials) so I could test drive it before taking it to the last test & tune this FRI. But there is so much ice and snow at the old rancho that I can't even get the car out of my driveway or load the car into the trailer. So looks like the car will sit in the shop until the snow melts.
