I have a NOS Wet Plate kit and I have been getting eratic activation on the initital hit. I have my Progressive controller(built myself) activating through a wide open throttle switch and then through a Fuel Pressue Safety Switch. My controller logs the Activation Input as well as each Nitrous and Fuel pulse, plus the 0-5 volt output frm my Wideband controller. I found that the fuel presure was dropping off on the initial opening of the Fuel solenoid. Since on my controller I can adjust each pulse of the Fuel and/or Nitrous solenoid I decided to advance the Fuel solenoid .050 second and give it one 50% pulse and then follow the same Progressive ramp as the Nitrous solenoid. What a differance this made! I am now able to spray through 1st and then get more aggressive in 2nd and then it is at 100%. When I shift I setup a Nitrous Resume Ramp that has two settings. The first allows a Resume Percent 10% to 100% and the second is a Percent PerPulse. For example when I shift to 2nd and the Nitrous is at 50%, I lift and shift, the controller would calculate 80% of 50% and pulses the solenoids then allplies the Percent PerPulse until 50%(where I let off) is reached. Then the normal progressive ramp takes back over unless I lift and/or shift again. This featuree can be turned OFF also.

Also has a graphic LCD screen so all logged Data can be viewed without a laptop. The Fuel ramp is fully adjustable richer/leaner for each and every pulse if needed. Or set points can be entered via a 2d graph and the Progressive ramp is auto calculated betwen the set points. Fuel advance option can be set to within .001 second.

Also can disable the Nitrous based on Wideband signal and three digital filter paramaters that are user adjustable.

Also have a 0-5 volt analog output that could be used to control fuel via EFI.

I am thinking about becoming a sponser, if one of the Moderators that is into running nitrous on regular basis would like to test one of these feel free to PM me.

I hope that I have not violated any posting rules here, I am just very excited at how well it is working. I had been trying to control fuel pressure when I just needed more control over the solenoids.

Also can store and copy multiple setups. Adjustable Pulse frequency. Built in help text also. +12V or Ground activation to work with existing vehicle wiring.

I can post some screen shots if that is OK.

I just want to go drive it some more now
