Way to rich on spray Trying to figure out why my car is so rich on nitrous. It was fine awhile back. It does it on my jetting for 75,100,125 shots. I thought my wideband was off but on motor its reading dead on 12.8-12.9 but as soon as you smack it my afr goes into the mid to high 9's. The initial hit feels fine but feels like its falling off up top. Theres an issue somewhere. I've pulled the feed line off the solenoid and cracked the bottle open its free flowing. I have a rpm/tps activated electric switch. I test fired the solenoid last night with the line off the car...there was spray coming out. Checked my jets/nozzle for blockage and cant find anything. Looked at the data log and the car is not adding fuel or anything for unmetered air. Bottle pressure isnt dropping either. Anyone have any ideas?
I got an idea... Stop spraying before you lift a ringland from being that rich... holy ****....
fuel could be puddling in the ringlands from being that rich and if it ignites it'll lift a ringland in a heartbeat.... be VERY careful.... lower than 10:1 is super rich... does the car blow black smoke when you spray it????
how is the system setup?? dry, wet? what? what is the jetting on both the nitrous and fuel solenoid?

holy **** 9s for afr, yes you need to not spray anymore and list up what size jets you are using and how much you are trying to spray! Is this kit a wet or dry, before or after the maf if dry kit?

Well I THOUGHT the bottle pressure wasnt dropping but it is 2-3 seconds into the run. Lost ~200-250 psi from 1st gear to middle of 2nd and kept falling from there. Had to have someone put a flashlight on the guage last night with the video camera taping

sounds like you had a bottle full of air. how many bottles have you gone through with the NANO system, you need to bleed of the air/nitrogen thats in the bottle. Can't really think of anything else that would have that profound of a PSI drop

I can see the bottle being full of air making sense because when I first tested my nitrous on this build I made one pull with the bottle closed to make sure the fuel noid was opening, straight to 9's afr(no nitrous at all, bottle closed).
I believe nano fills his bottles though, which I know they bleed off the extra air/nitrogen, unless he had it fillled somewhere else the last time.
