yo i dont want to sound like a moron but what is a ODBII...is it like a fuel/engine ecu type thing

 

I would have gotten a manual, but I drive in Manhattan everyday so I got a auto


Actually I mistyped it before...it's a OBDII or OBD2. An OBDII reader plugs in to car and it will tell you what the CEL stands for. If you have a CEL, after plugging it in, it will display some numbers. You look up the # in the manual and figure the source of the problem. (example: 0218 = Transmission Over Temperature Condition ) After a few minutes, the OBDII turns the off CEL. If you do not fix the problem, the CEL will come back on.

You can goto a Toyota dealership and they will charge you $50-$75 to diagnose your CEL by doing the same thing or you can get your own:

Hey...ty6

I noticed you have the TRD exhaust with the DC headers. Did your car sound like this or is it better?

its cool i got an auto too ]

 

It sounds like that, a little "ricey" (forgive the phrase), but I've kinda gotten used to it[/quote]

 

why does the CEL come on when the headers are installed?


I just heard the sound clip for headers, CAI, and TRD exhaust...it sounds nasty!!!! why do you think this is?

 

Because it's recorded on a video camera, so the sound qualities not that good. Also, he recorded it with his car driving between rows of houses, so the sound echos all over the place.

I have the same mods as he, except for the air intake, and mine doesn't sound bad. At least, it doesn't sound like that at all.

 

The stock header has a built in cat. When you install the DC headers, it removes this and causes the 2nd O2 sensor after the headers to set off the CEL for higher emissions.

The TRD exhaust probably wasn't meant to handle (sound decent) the extra amount of exhaust that the headers help spit out. The TRD exhaust sounded nice with the stock setup and a CAI, but with the headers, it becomes another coffee can civic.

 

It's definitely a matter of opinion.

I do agree, though, that the TRD exhaust probably wasn't set up to handle the extra flow.

Also, I still have yet to install in air intake, so maybe for me that will make difference.

 

maybe with the redesigned DC headers, they'll add the cat on causing it to have a lil less airflow making the exhaust not as loud....just a thought

 

It's possible.

I was just thinking to that it seems to be louder on the inside, rather than the outside. I'm going to dynomat my whole car anyway, so I think that'll help.

 

OBD2 is the type of EEC (Electronic Engine Control) system is on the vehicle. Most all cars manufactured after the mid 90's have ODB2. The government regulations pushed the industry to standardize the emmision control sytems. OBD2 is nice because with the right tools you can not only read real-time data but actually make some changes to the system.

 

Day 6: And the CEL comes on!

I didnt' reset the ECU in the first place so maybe I'll try that, if not, I'm going to put the stock header back on.

 

Ahhh f$#$@&& hmm i was hoping it didnt man i guess you have to focus your effort on that o2 sim before you take off the header. If you cant find one then do so. good luck man. O yeah reset ECU .

 

damn....let us know what happens after the reset

 

Thanks for your support guys! I'll let you know what happens.

P.S. Where would I find the o2 sim you are talking about? Just incase. I'm not a quiter!!!

 

Man i really dont know , there is a link in this section just go through the forums. Try the

http://www.clubsciontc.com/ they have info there in the engine section.

check these out specifically.

well thats all i have found on this man good luck .

 

Wow, man...I didn't expect that. Thanks for searching up all those links!!!

I tried the ECU reset that I found in the search on this site, but it didn't work for the tc. So, I'm going to try and pull the battery cable, and see what happens there. I didn't have time last night because I had Sh** to do.

No one seems to know how to reset the tc's ECU without pulling the battery. Oh well, guess I'll have to re-do my presets.

 

You prob. know this already but just in case you do not, don't foget that if you disconnect your battery to reset you ECU, you will also have to reset your power window computer, here's the how to link:

Thank you very much gwtc!
