Nitrous tuning questions I'm having some issues with my nitrous setup and looking for some input. Pretty much the a/f in 1st and 2nd gear is 11.8-12.0 but once it goes into 3rd it goes super rich, like 9's afr. Car is an A4, plate kit with a dedicated with c16.
Hoping somebody has had a similiar issue.
Doubt it's a bad bottle fill. The nitrous from purge is a healthy white color, not clear

What was your pressure after purge ?
Betting that was the issue.
How may passes and at what shot ?
Have a bottle heater ?
May need a NANO kit...once a bottle gets a little low, you lose pressure faster. A NANO kit makes use of almost a full bottle.... so I heard.

Could be a combo of lean spike on initial hit then rich once you get the load on it. Rich is way better than too lean!
Maybe your fuel system is getting punched in the face on the hit and then catches up? A leaner jet would be needed after you work that out.

I have a dedicated by the fuse panel to help with lean spike. Tuner put a fatter jet in to help on the hit cause it was lean.

OP, for it to go from 12:1 and straight to 9:1, that tells me that the nitrous solenoid clicked off at some point. Do you have a progressive controller or anything? What bottle pressure are you running? What jetting is in the plate? Also, did you set the flowing fuel pressure on the dedicated fuel system? If so what did you set it to?

If that doesn't work then I would do a consumption test on the nitrous side, if it is flowing enough nitrous that means there is too much fuel, if it isn't, then there is a restriction on the nitrous side, either one can cause a rich condition. If you need help with any of this just send us a PM!Thanks,

Okay, have an update. Put the 100 pills in the car and went out and made a pass. Instant 17-18 afr. Got home and cracked the line open from the standalone to the fuel noid. Only air and tiny,tiny amount of fuel seeped out. Not getting fuel, so I disconnected line from plate and put in a bottle and jumper wired the fuel noid. Got all air out and a steady stream of fuel coming out. Hopefully I'm moving in the right direction.....

How often have you done this? Reason I'm asking, is the kit isn't getting fuel again. I don't get how this is happening. Can't believe that air got back into the line from regulator to fuel noid again. Haven't cracked the line open since I assumed the problem was fixed....

I don't know what fuel setup the OP has, but we have seen where, on larger regulators, the bleeder actually helping keep the regulator open and not "chattering" on the initial hit. You guys should really get on the same page with your technical advise. It can be confusing to your customers.
