well I have the stage 1 kit from AIS and everything was all fine and dandy, but the pump went bad due to it being mounted in a bad position(gets wet). SO...I sent it back and got a new upgraded one and reinstalled everything today, but my afr is much leaner...

Previously I had and 2qt tank and the pump mounted on the front bumper. Now I have the pump mounted inside the engine bay close to the passenger side next to the engine mount. I am now using the windshield wiper fluid container as my tank too. The pump sucks from above the tank and I just fed the tubing from the pump down into the bottom of the wiper fluid tank through a small drill hole just below the top neck. Im scared to tap the container because of how thin it is...

I have "trouble shooted" everything and hooked the power directly to the pump and it is indeed spraying. I did some pulls and it feels as if it spraying because I have an led light that comes on, I jumped out and touched the supercharger and it was cold, and the line leading up to the check valve is full of liquid. I saw low 13s and i immediately let off. I popped the hood and checked everything and got on partial boost to let some meth spray through and then got on it and it read high 11s, so I was excited and I thought it was in working order, but the last two pulls I did it read high 12s, low 13s...so now I leave the thinking to you guys....

 

sell it to me and get a new 1 lol ile figure it out.

 

if I were you I would buy a trunk mount 1.5 gal tank with the pump in the tank cavity, take the spare out and put it there next to the battery. I would buy an aquamist sensor to detect blocked nozzle; I did this it works fine all the time

 

nozzle isnt blocked and checked all connections. I unscrewed it and gave the pump direct power. It came out perfectly...mine was working fine too, but the pump was getting wet whenever it rained and it finally gave out after awhile...AIS sent me a new one, so today I just reinstalled it in a dryer place to prevent it from failing again

 

bump....gonna check connections to see if they are clogged...does anyone think i need a retune because of the different pump and I am using...I am still using the same mixture and jet, so I didnt think it would be necessary.

 

You should not need another tune if you are running the same mixture and nozzle size. This kit runs off of a pressure switch hooked to a vacuum line correct?

My nozzle was clogged with the smallest piece of debris and it was doing this, but you said you unhooked it and it was spraying?

I would start from the beginning, fuses, then test the pressure switch, then you already said the pump. If all works, is your vacuum line crushed or connected properly?

 

Make sure the nozzle isn't clogged x3, lol.. Mine did this! It wasn't good.

 

The meth is spraying....I did some low boost pulls and adjusted the boost switch to a lower setting so it would spray without going WOT. It now sprays at 5 psi and I know the meth is spraying. I did 30 top 70 at 5psi and my led light was on and the charger was iceeeeee cold. So the meth is spraying fine....I dont really know what else to do. The afr on a WOT pull is between 12.2 and 12.7. I think I need to get this tuned squared away...it was tuned to be between 11.4 to 11.8 but is running much leaner


Also, the last 3 weeks I have driven the car daily, but the car never saw boost because I had to send in my pump...IDK...

 

I would not run wot at 12.7....

 

i know....i shut it down...but those are the kinda numbers I am seeing when I floor it for a short burst.....Any tuners in eastern Pa???

went out and checked all the connections for the 3rd time and unhooked the jet from my tb spacer and put power to the pump and it sprayed correctly, so the meth is working, but the car isnt acting how it used to. I even added some straight methanol to try and richen it up, but all I see is low to mid 12s and I really dont know what to do next. I just cleaned my maf sensor during install so that isnt an issue. The plugs look fine and they only have 3000 miles on them...

 

Well if you know for positive that it is spraying then you might need to tune it again to richen it up.

Just because you put power to the pump direct does not mean the system as a whole is working, did you test the boost pressure switch, or maybe a portion of the nozzle is clogged, or the check valve...

 

check valve works. we hooked an air compressor to the boost switch and it turned the pump on. so I think I may need a tune...thank you for the suggestions and help I really appreciate it!

 

Talk to BoostedYards86.. He is from PA and is quite the tuner or so I hear. PM me your info and I will send it along to him.. As in. What part of PA etc. I will get a hold of him. If by some miracle he may check this thread out, but I doubt it. He's mostly on RLF.. Only PA tuner I know of.

 

I am area code 19465 in Southeastern Pa, but I think I figured my **** out...I completely drained my washer fluid tank and then refilled it. I think there was water left in the bottom which made the mix weak...idk.. Anyway I mixed and added some straight meth and I did some 3rd gear pulls and I saw high 11s....I think I am gonna buy hptuners soon cuz I am tired of not being able to tune...and having to rely on others...nonetheless thanks for the help and suggestions

 

i would


run a line from the out side of the pump up the windshield and brake boost the car to set activation point and see if it sprays.

 

That or set up a test light on the pump. Go out and brake boost it till the light comes on. That or get fluid all over the car.

 

The AIS systems have a pressure switch on the pump. The pumps work by maintaining pressure in the line. I believe you rotate it in more for more pressure, and more meth and out for less. Even though the nozles are only rated for one amount they do flow higher with more pressure , as you would assume.

Seeing as you changed you pump the settings on the pressure sensor may be different than what you had. I am not sure if it would throw your AFR's off a whole point, but, you should see if you can adjust this switch and turn the pressure back up before you retune. Hope that helps!

 

add more meth to your mix to richen it up

 

i have an led light in line with the pump, so when it turns on it lights up. I have the boost switch set back to the original setting. It comes on at 7psi the afr is good, but leans out at 5000 and thats when I let off. It is high 11s and once it hits 5000rpm, it leans out to mid id 12s so I let off. I have not gone to redline yet. Again I have added straight methanol and 2 bottles of heet to the wiper mix to achieve where I am at now. i was tuned for windshield wiper fluid 30% at 11.4 to 11.8 but now my afr is much leaner. Maybe altitude or temperature difference, but I am going to be purchsing hptuners shortly so I can see whats going on and adjust afr accordingly. My timing map is pretty conservative so I know the car is safe but its just running lean.

 

John, can you do me a favor and pull the jet out. Use some carb or brake cleaner and spray the nozzle out. Then there should be a pressure adjustment switch on the pump. You might need to contact AIS to see how to turn it up a bit. Since the pump is not set exactly the same, the psi might be lower and you may not be getting the same amount of meth spraying when it activates. This will cause the tune I dialed you in for to be off. If you need your tune file, I can send you it via email. Let me know if there is anything else I can do bro. You know I stand behind my work.

 

The pump I am running now is supposedly running higher psi(250...set at 200) than the last one(150psi set at that) and I just used some brake cleaner since thats what I had laying around to clean the jet. I am running about a 60% meth mix right now which is more than the straight windshield washer fluid we tuned it with (30%). I am great WOT in the earlier rpms...it is running running 11.3 to 11.8 til 4750 and then it leans out to mid 12s. I havent gone past 5000rpm since I see 12.5 AFR so I let off.

 

Just talked to rodney and went through everything. The pump is working and it is spraying at a higher rate then the old one, so looks like I need a retune for whatever reason...Any suggestions since my tuner is across the world. :/


Also willing to travel a few hours as long as I get this thing running perfect again. As of right now, buying hptuners myself is out of the question...
