Intake issues

[InfamousDragon]

So I'm a lil old school when fixing imports and this yaris is new to me so help me out if you would people. I put together my own intake with a very large filter haha. Anyway here are the problems I'm running into. The intake goes from the lil 2 inch port to a 3 inch maybe 3 1/2 inch filter. It's a big filter for the car I know but I want it to get plenty of air and stay nice and cool. 4 cylinders get super hot if you don't know. Anyway I did the install properly I know that for a fact but I still get the check engine light and when I drive the car the throttle does not respond its like its bogging out. Well it just started doing that after I fixed the intake connections but before I fixed it it was running fine now well I should have taken a break while working. So I need to know how to reset the check engine and the ECU on this crazy lil car. Lil help for an old school from you new school

Hey Dragon, :smile:

Are you able to post a pic of your intake? That would help to pin down the issue. I also enjoy seeing the clever ideas people come up with. On your new intake, did you move the mass air flow sensor? If it does not remain inside specifically sized tubing your engine won't run right and you'll get the check engine light. Don't try to run your engine if it bogs down. That could be indicating an overly lean condition. and do damage to your engine. The MAF sensor is this black thing with the wires plugged into it...

By the way, there's nothing wrong with being old school. :wink:

Ill take a pic tomorrow for you hopefully your online. But yea the pipe is a lil bigger. It was running fine yesterday but its not a short ram lol. I will work on it again tomorrow. I had it running fine but needed to fix an issue. I took a huge filter from SS and got a bendable pipe with the mass flow connector and the hose conector pipe. It will be easier to show you when i take a pick. Mainly what I have noticed though is you can't use longer piping haha funny lil cars though. I did a few mods to the car but the intake is my main mod now.

Was the MAF sensor and tubing made for a Toyota 1.5 intake? If it isn't exactly the same diameter, it won't work properly. I think the proper MAF diameter is 2.25 inches. You're right about not being able to use longer tubing. If you do, it puts the air filter inside the wheel well.

I also run an oversized filter that would flow on a V8 engine, so overall length became an issue. But I crammed it in anyways by making everything else as short as possible. The filter mounts onto a 6 inch diameter velocity stack.

You can do almost anything you want on an intake as long as that small section of tubing where the MAF sensor is the right size. :thumbsup:

No as I stated its all bigger but again I had it working properly. I am about to go work on the car right in like 15 mins. So ill try and take pics on my iPad and post them so you can see. I think I forgot to connect something though ill let you all know

I'm sorry but the number of cylinders on a vehicle makes 0 difference on how hot the engine runs.

Ok. :smile:

[InfamousDragon]

Ok well I took pics but could not upload them you got an email or something I could send them to you? So I fixed the issue an it was doing fine but after a while the engine light came on again and the cruise control stopped working and the traction control turned off. So I'm curious what's up with this car. It's all new to me so this is actually nice to not know what's up. So teach me people thanks old school needs to learn the new school

What really helps in posting pictures is a Photobucket.com account. It's totally free. I store all of my pictures "in the cloud" at Photobucket. To post a picture, you just copy the image link of a picture in your library and paste it into your post... and wup, there it is. :thumbsup:

This is what an image link looks like:

Sounds like something came unplugged. Your car might run semi-ok while the computer is learning the new parameters and then when it figures out what's going on, you get the codes.

Hey, do you know about resetting the computer? Take the negative cable off of your battery and leave it off for a few minutes, and then reconnect it. That will reboot the computer and it will relearn any new parameters.

If you want to send some pics, my email is:

Ok I have drop box will that work? Ill see if I can get into my photobucket

[tooter]

What's a drop box? Hey, we're almost communicating in real time.:smile:

[InfamousDragon]

Lol yea we are. But yea drop box is like a file upload for iPads and phones to store pics and what not. Anyway it's just like photobucket but better.

[InfamousDragon]

That's cause your in la and I am too haha

Thats some bend you've got there...

Yes, it works. :thumbsup:

I can't see where the MAF sensor is, but if it's in that shiny tubing its diameter appears to be too large. I wouldn't be concerned about the 90 degree bend in your flexible tubing. That's not causing any problems.

I've experimented with a lot of various intake designs, so this is just for illustration. See how the tubing diameter is larger in front of the MAF sensor section and then smoothly necks down? You can have larger tubing in front of it, but the tubing needs to be exactly the right diameter at the sensor itself for it to give accurately indexed readings to the computer.

Here's another example: I'm running a larger throttle body and this intake tube matches its throat diameter. But notice how it still needs to reduce down to the proper diameter right where the MAF sensor is?

And I was wrong about the diameter...
It's not 2.25 inside diameter. It needs to be 2 inches inside diameter at the MAF sensor. If you want to get some pieces of tubing to experiment around with. Here's where you can find inside diameter tubing especially sized for intakes:

intakehoses.com

I buy all of my intake tubing from them and they're great to deal with because you can get small pieces for very little money.

So the diameter of the tubing at the MAF sensor is my best guess as to what's tripping the codes. :smile:

[InfamousDragon]

Ok that's something I now know here is another question though, is there any way to reprogram the sensor or the ECU to match the tubing I have now so I don't have to switch it at all? Honesty I like the 3 inch diameter tubing look and sound. I tripped the check engine again after a few times of starting the car but the damn thing runs like a beast with the setup I have and sounds like a monster. The only two draw backs other than the cel is the traction control and the cruise control not responding at all. Curious lil twist for just installing an intake lol.

Anyway what I want to do is just retune the chips if possible but again it's a new car not used to the way it works. I took pics before I repositioned it and what not but still imma play around with it till I figure out what I can get away with you know what I mean.

So basically imma open another thread here tomorrow about all the things I have done and how the car is responding just for feed back and tips you know. Always good to get advice and what not. But I wanna fix the intake ASAP.

So I drove it around and raced it a bit like I said runnin like a beast. You can feel hear and deff tell the difference with the intake so I wanna leave the setup. But I want to fix the codes and get everything working like it was but with the new intake

Not that I know of... but there are many others here who know a lot more about electronic tuning than I do. I only operate within the parameters of the stock ECU.

Many of the electronic functions overlap and share the same information.

Yes, I do. :smile:
Man, I've tried try all sorts of offbeat intake experiments. I just make sure that they are not irreversable.

If you find a way to do that, be sure to share the information by letting everyone know. :thumbsup:

Lmao yeah I'm a computer techie lol. Well I will play around with it as always but I need a pipe that will fit the maf then you got one haha I could use it right now lol

[suckerface]

I'm sure CTScott will chime in, but as far as I'm aware, you can't reprogram the ECU for the larger pipe diameter at the MAF. If you want to run that size, you'll have to go stand alone or piggy back. Toyota's ECUs have yet to be cracked.

[tooter]

You already have one right now... :smile:

http://i17.photobucket.com/albums/b90/compost_bin/car/IMG_5956.jpg

It's the plastic casting with the MAF sensor mount on it that's part of the stock air box. If you didn't mind destroying your air box you could cut it off, grind the intake end round, and attach the rest of your intake onto it.

[InfamousDragon]

Yep already destroyed it and thought about doin that but gotta do a auto repair for a friend but ill get right on that lol make shift Mickey Mouse fun my kinda work yaaaaaay.

Ok well some good I advise on a stand alone setup and a piggy back for this car would help.

It's runnin good the way I got it now just the cruise and the CEL along with the traction control lmao other than that I'm in beast mode temp haha and sounds super mean
