Okay... first off I'd like to say that I'm in Cali... where smog = So, with this said, this is more for the Cali heads. I was curious how to pass smog (when it's due) if you have an OBD2 car w/ a mild to aggressive engine build using Hondata, Crome, Uber, etc.? If you have a mild build on the engine, do you simply plug in your original OBD2 ECU and go for a smog? I'm curious to know because I plan on purchasing some goodies for my girl, but want to be prepared when that time comes to smog. Some info on this matter would be great. Thanks.

 

There was a thread a while ago where someone figured out a way to toggle between programmed race maps and stock maps. That could be one way.

Or you could swap in a stock motor, get it approved, and then put your built motor back in

 

find a friend who does smog.

 

if it is the original motor that belongs in the car it is easy to pass. if it is a hybrid then it needs to be bar'd first then it's easy. what do you have in mind for a mild build?

 

Well, this is what I've got:

Skunk2 Stage 1 cams
Skunk2 IM
Cam gears
JDM ITR pistons
DC JDM 4-1 header
Greddy Cat-back exhaust
AEM CAI
JG Redline Series head w/ PnP and upgraded valvetrain
J's lightened flywheel
ACT clutch
Chipped P28 ECU


My car is a 96 Integra GSR. I plan on swapping out my cams with something a bit more aggressive; getting a better header (Rage, Hytech, SMSP... jus' something better than what I have); Hondata or Crome; and of course, a good tune. My goals are to get in the 200-210 whp range.

[b] X 2 ...

 

Going to reitterate find a friend who does smog.

I was just on the AEM/ DC sports site. Any JDM spec parts, particularly that JDM header you're putting on, doesn't pass CARB standards, thus illegal in california. You can pray the smog guy won't auto fail you for it, but if he's an *** you'll fail the visual test.

Check the quote. I have almost everything u have. My car passes smog. All u need to do is put on a stock or CARB approved header, plug in the stock ecu and u should b ok. Thats all i do. I guess u may possible need to zero out the cam gears. Also put the timing back to stock, 16 degrees i think.

Of course it depends on the car too. Some motors just pollute more then others, even in stock form, depending on the condition of the motor & its smog equiptment. But if everything is in good condition u should be ok.

 

sorry to say, put your gonna have to get rid of the obd2 **** if you wanna tune it. i'm a smog tech in nevada and if an obd2 car doesn't have the right obd2 computer to connect to the smog machine, failure. i'm sure california is the same way, if not stricter. just get a po box in an outlying area that doesn't require smog and register your car to that address. or get a friend that does smogs.

 

I've considered that before. I guess there are certain areas, i think mostly in northern cali, that dont require smog.

But yea, u can run hondata or what ever else on an obd1 ecu w/ a conversion harness. & then for smog just unplug it & plug in the stock obd2 ecu.

along with all the other bullshit obd-2 sensors that the obd1 computer ignores. if i were you, come smog time i would put the stock cams, exhaust manifold, exhaust w/ stock cat, stock airbox, stock injectors in and then plug your obd2 computer in, drive it for a week or so, THEN go to the smog statio if the check engine light hasn't come on by that time.

that's pretty much exactly what i did last week. converted EVERYTHING back to stock obd2 on my 00Si. (except for the ctr cams/pistons/maxbore'd TB/aem cai) i drove around to set the readiness codes, which only takes 10 minutes if done properly. as long as you set 3 of 4 readiness codes and have no CEL's you should pass.
