I put it on, ran around for a little bit and threw a CEL after about 10 miles. Its running too lean

P0171 System too lean (Bank 1) <---generic codes

anyone got the Scion codes??? maybe its more specific...

did you let it idle for at least 15 minutes? you have to let the car adjust itself to the new airflow. Its a trick I picked up after installing my first intake on my Matrix a couple few years ago.

dang 15 min

dang 15 min

Yup, just long enuff to pick up the tools, wipe them off, put them away, and do what ever clean up.

oh wait think I found the problem.

how bad is it running like 30 miles like that. lean and all

not that bad, lean is worse then rich, but for 30 miles it aint anything, if u kept it that way yer car wouldnt last long

That's why I wouldn't f*ck with weapon R...

You probably pushed it too hard right away... You gotta reset the ECU and then let it idle for like 5 min... Not 15!! That's a little excessive! But better safe than sorry I guess?

If you just toss it on and then go redline it, you'll throw the CEL

Ray at WR adressed the problem. thanks Ray

I'm no expert on anything according to some peeps, and just speaking from experience. Out of all of the intake installs (over 12) I've done, it has worked for me and have had NO CELs.

What did Ray at WR say?

Newb. What are you hiding behind your back? It's it's it's...a CEL! Hehehe, just kidding Brad!

And yes, Weapon R isn't very reliable...

Hey, hey, HEY!

I resemble that remark. Thank you very little! :wink:

Long time ago, it was a common practice to let the ECU recognize any changes for a few minutes before running the car hard.

Today’s ECUs do it in milliseconds. To share with you a real life experience, having our customer’s tC strapped to the Dyno, we installed the Air Intake, started the car, pressed the green button on the Dyno control, and run the car to red line, 1st run. Jump to the office to see the results, back in the car, started it again and to redline 2nd run, no CEL/DTC.

There is no reason why a quality Air Intake, properly installed generates a CEL/DTC. There are a few cases related more to the installation than anything else that could generate CEL/DTC. If the intake is not properly tighten after the MAF, this could generate problems, because the computer receives a signal of the mass air sensor that actually does not match what gets to the engine, or if the ignition is switched ON with the sensor unplugged etc.

Every time you are running lean, back off the throttle, take it easy, if you push it you might loose it, and loose it big. Running rich is not so bad, because you might take advantage of the situation and make more power, but if you drive for an extended period of time, it will produce damaged spark plugs, pistons rings etc.

check the vaccuum lines and clamps on all hoses.

actually try calling weapon r becuase i had the same problem wit the intake on my car and i called weapon r and they said that they have had a few problems with the piping and they wanted me to send the intake pipe back to them to rework on it. they said that would solve the CEL light problem

...There is no reason why a quality Air Intake, properly installed generates a CEL...


Yeah, but he said Weapon R! :lol:

Always disconnect your battery during an intake install, and let it sit for a while... Reset yer ECU...

Wait... Weapon "R" stands for "Weapon Rice" right?

How much HP Gain is that Weapon R? I heard it was a 13 HP Gain but when they dynoed it, the hood was open..Does that matter?? or what??

how do you know if your car is runnin too lean or to rich with out a controller?

or was this installed and tested with a computer... im lost am i missing something?

when he checked it with the OBDII code checker the code siad it was running lean

They redynoed it at 6.5hp and the being opened makes a difference unless you drive with your hood open on the road.

dyno with the hood open doesnt make that big of a difference, it helps to balance out the fact that there isnt a rush of outside air going into the cars engine bay. other companies do this too. on the road you would actually make more power becuase the dyno fan in no way can compare to 60mph rush of cool air, unless you have a wind tunnel you can dyno your car in.

Alot of companies dont dyno with the hood open, they use large fans to simulate the rushing wind.

like i said, the dyno fan will not "simulate" rushing wind, have you ever stood in front of a dyno fan? that cant even be goin 30mph. if you really wanted to simulate rushing wind you would need a wind tunnel. thats one of the reasons why everyones dynos arent the same, there are many factors in putting a car on the dyno and that simulated air is one of them. im too lazy to look for the article but in sports compact car they had somethign about dyno fans not simulating real wind.

and i didnt say a lot of companies dyno with the hood open, i said other companies do. if you really want to find out go call other companies and ask how they dyno cars lol. and as for having my hood open, being in san jose in a building at 80 degrees in doors, you do one run and you already have heat soak on the stock airbox.

That's why I never really look at dyno numbers... In the San Fernanda Vally it's a steady 100 degrees in summer... A "cold" air intake isn't going to work the same.

Good news. i called creativecompacts.com about the weapon R issue and the dude said there shouldnt be a problem having CEL light cause of this intake, but as of today Weapon R is redoing the intake for minor mistakes. This will take 10 days intill creativecompact.com will start shipping the product and recieve the better version of the Weapon R secret.


what i've heard the Weapon R is compared to the AEM V2. This weapon r packs a better punch then all the CAI available right now if you said the engine is running too lean. with the weapon r being redone and available in 10 days, i think we should have second thoughts about the intake.

I am testing the "new" versoin of the S WR intake. So far so good. We put it on the car yesterday and no CEL yet. Last time it was after less than 10 miles. We'll see after the weekend and after I put some more miles on it.

keep us posted please :)

I have this intake and have had it for 5 months. After I got the final product they made a small change with the sensor placement which is what made the car throw a CEL. It was a stupid mistake, yes, but they have fixed it and what you get will be the exact same as what I have now.

Just a little info:

The intake that I originally dyno'd at 12.91 hp was NOT the same design that was dyno'd at 6hp. They increased the length of the pipes AND it had a very large (almost 90 degree) curve. They believed this curve was causing air flow to slow and also believed the sensor had to be placed differently. They moved the sensor a little farther back from the filter (as it should be) and to the side (it enters the pipe from the side instead of the top). It sounds weird and you realy don't have to take my word over anything, but i feel a VERY BIG difference in the final intake design. The torque as definately increased. I anticipate great numbers this upcoming weekend when I dyno my car with my new cat back exhaust.

Originally our dyno showed a slight loss in torque. This IMO could have been because of one or none of two things:
1. We did not run the car long to let it get used to the new intake before the dyno. This could have been an issue I dunno.
2. The intake was a prototype. It was shorter and less efficient. I could feel the lag when I accelerated, which is why I originally didn't like the intake. Now that my car is used to it and with the new design, it accelerates a lot faster.

I think that you will be impressed...especially when the cold air box is through with production. I can't wait to get one!

do you have a dyno of this non cel throwing intake? also, how would i go about purchasing one?

The original dyno was of the prototype. I only have the paper copy.
Like I said I will be dynoing my car again, but with exhaust sometime within the week.

You can purchase it through www.creativecompacts.com

kewl, what mods have you done to the exhaust?

also, how is creativecompacts able to sell the intake for $180 when its $283 from the weapon r site? j/w

bump. i'm curious on the update on this. Thinking of buying this Intake rather than just a drop in filter :lalala:

Right now we are selling the intake for $180 + shipping until Feb 28th. We are able to offer the intake at this very low price because we worked with WR directly to prototype and develop this intake. We were also exclusive distributors on the intake for the first 60 days it was available to the market. Price will go up on March 1st, so order before then for the discount.
