help, FJO nitrous mini controller I have a strange problem with a brand new FJO controller just purchased last week. I have it wired according to this schematic http://www.fquick.com/garages/viewga...wimg&id=120876 and the ground for the solenoids never activate. The light comes on when I hit the 3000 rpm mark and the orange light comes on at WOT.
The large ground is good.
Here are my current settings...

One problem I see is that you have your FJO set to only open to 50%. Solenoids IMHO should ALWAYS start at a certain percentage and ramp to 100%.
For example if your using a 100HP, shot don't try and ramp to 50% for only a 50 HP shot. I hope this makes sense.

You would have to have a +12v on input #2 wire on the controller for the nitrous to come on with that configuration. The input #2 wire is not even on that diagram, but it should be on the FJO manual. Click the pulldown at the top and set it to ignore, should fix your problem.
It's a little hard to understand but it works like this. "Stage 1 will.......... :insert message selected in pulldown: ....." Right now, you have "Stage 1 will activate with 12 volts" So unless you've got the arming switch also sending some juice to the input #2 wire, it's not going to work.
The input #2 wire is used to select between, or activate the second stage using the pulldown menu. I have both "stages" of mine wired together and use the that pull down bar with a switch that sends power to "Input #2". Both of my stages look identical, but one has the 1st gear lockout box selected. I use my input #2 as an on/off 1st gear lockout switch.
Also, if you uncheck the RPM box, you can test the system out with the car not running with just the key on. You can hear the solenoids clicking from inside the car. Pull your fuel pump fuse and let the car run till it dies out, then turn the bottle off. This way you won't fill up the manifold with fuel.

Okay guys, thanks for the help. I have it working now. I would call it a software glitch. The controller will not work with the final setting at anything other than 100%. Here's my new settings that will pulse my test LED successfully. Now to try some funny gas.

Cool, got it working. Now I need to figure out this DynotuneNitrous 02 controller. I have it connected to input #2 to kill the juice under lean mix conditions. I have a FAST wideband to hook to it but no data on how to hook it in.
I have my ground on the control side of my nitrous relay feeding into my shutdown switch to kill the system. I have my shutdown switch set up provide a ground until a lean condition, works like a charm. This leaves my input #2 set up so I can switch between 2 different FJO configurations on a single kit.
