If only it wasnt so ugly

Beauty is in the eye of the beholder. Do you want to go fast, or do you want to go fast safely?

What? 15:1 AFRs arent safe.. pfft

After doing some testing like 860 suggested. The fuel noid is opening at least a second after the N2O noid.

Time for a rebuild or a replacement, or converting to dry.

Brand new noids. And its a DP setup, 2nd stage is a dual dry though

scapaldo

What do you guys think of my jetting though?

Well brand new noids can fail, and that's any brand. Any massed produce item has a known accepted fail rate. Now with that said, try bypassing your wiring and go directly to battery with noid and see if it still does it, might show if it's the progresser and/or wiring. Sometimes progressing doesn't work so well. That's why I prefer multi stage. Dry 2nd stage, great.

I should have mentioned, when the fuel noid is hooked up solo it works and pulses as it should.

scapaldo

I actually wanted to do a direct port dry setup initially but I dont have a precise enough way to compensate with fuel.

scapaldo

I upgraded my power wires and the delay is gone. The fuel noid activates as its supposed to when the controller isnt hooked up. Hooking up the progressive controller causes the fuel noid to open and stay open while the n2o noid pulses. Again with the n2o noid disconnected, the fuel noid pulses as it should.

scapaldo

Is there a wiring diagram for that CFN controller that you could email or link me to Robert?

scapaldo

Anything? I just like seeing how things work before ordering.

If you order the 2 stage controller you can control the resevoir factor that 860 talks about by running the nitrous on one stage and the fuel on another. You start the fuel first and have it come on faster and run at a higher start percentage than the nitrous.

The pulsing is keeping energy in the wires keep the fuel noid open. IF both wires at the noids are equal length and sliced together at that point you problem should go away.

So you thnk the problem might be the length of the lead wires after they split to the noids? Ill definately give that a shot. They split and the N2O noid has about 10" before the noid and the fuel has about 20" before the noid.

srsnow

I don't get it, are you suggesting that the wires are acting like a capacitor just because they are different lengths? The length of the wires shouldn't really have any effect on the operation of the solenoids. Can you elaborate?

It is dealing with voltage drops. ? is how do you know the fuel noid is just saying open. Or is it not opening at all.
Not opening at all makes a little more since. If the voltage drop on that wire, is high enough the fuel noids would not open seeing how there is not enough voltage to open it.

IF your wire that is connecting to the noids is not of the right size, or you have an iffy ground. You will introduct a voltage drop. The nitrous noids coils are lower voltage coils then the fuel. The fuel noid may not open IF you introduce a large enough drop to take it out of its spec voltage.

Also once a coil in activated and deactivate it creates a back voltage flow. So the progressive is cycle on and off on and off. The noid will only close if the magnetic feild has collapse. If the off voltage time is not enough for the feild to collapse the noid will appear to remain opened. The nitrous noids collapse could give enough back voltage to keep the fuel noid open just long enough to have the ON power hit it again. All the time the magnetic field is trying to collapse but there is enough power that if appears to remain open. Just like a fuel injector in peak and hold. It takes a good amount of power to open, but very little to maintain open.

Hope I did not butcher that too bad.

I disconnected the noid from the D-block and ran the outlet of the noid to a container, activated the fuel pump, and triggered the controller, the n2o noid clearly pulses while the fuel noids just opens and stays open. Without the n2o noid hooked up, the fuel noid pulses as it should.

The ground and power wires are now as perfect as I can get them, no less then 14g wire anywhere, bigger where necessary.
