theres certain "rules" with engine changes. for gray market vehicles (foreign vehicles, shit like that) it must have all emissions components on it, and get inspected at a BAR referree. but for a domestically sold vehicle, you can only have an engine that was sold stock, in that car, in that year, in california. you cant put "heavy duty" engines in "light duty passenger vehicles". heres all the rules.

my s14 barley fails at 15mph but passes nice on 25.. its nox are high.. ive repaced all kinds of stuff (new cat) egr lines etc..... can u tell me a secret to pass... i know u guys dissconnect things to help it out lol....

OOps n/M just saw vvti s post.... lol.. ill figure it out... hope u get some work in.. its tuff all over the country.. especially CA........

so you replaced the egr and cat and its still failing? double check the timing (too for advanced creates NOx.) NOx is also an indicator of lean fuel/air ratio and/or high cylinder temperature. so if it gets serious, check for stuck closed or clogged injectors, carbon deposits, and small gnomes that run around inside the exhaust.

not sure if the ecu was changed into a 5 spd how can i tell

I don't have a 5spd ECU near me. But I do have Auto.
If it has "A18-B93 GO l" written on it, it's an Auto ECU.
You don't have a buddy you can swap just to test?

[sc ka24e]

cool yeah ill check it..it didnt pass by about 10 points in 15mph i even used that gaurenteed to pass ish.. but no luck... i found a brittle line that runs from the egr to bpt valve and fixed but havent gone for the retest.. also on the bpt valve when u take it off,close all the holes and blow in it is it supposed to escape air..?? cause this 1 does.. and im not sure if its supposed to seal air or acts as an exhaust

im not really sure. the bpt valve is supposed to allow manifold vacuum to the egr to turn the egr on when there is sufficient backpressure in the exhaust and load on the engine. try restricting the exhaust to create backpressure (restricting, not completely blocking) and see if the car shudders or dies. if the car does, the bpt and egr should be working correctly.

i have an s13 with an sr20det redtop. how many hundreds should i leave on the seat?

from what i heard, sr20's run cleaner than ka's stock for stock. hopefully you can fool the tech doin it since theyre both nissan motors?

[sldbyuramg]

word...thanks for the info

on OBDII cars is there a check on SRS airbag systems and what exactly is checked?

we dont check the airbag systems. we plug the smog machine into the pcm, and it checks for emissions related dtc's

What kind of training/schooling do you need to go through to be a smog tech? How's the pay?

[techn9ne]

to get it through ase's and actual work experience, you need 2 years in a shop, your A6, A8, L1, and clean air car course, advanced clean air car course, 2005 update, and 2007 update. then you have to take the test.

pay depends on experience, and since im young (21) and my boss is a penny pinching piece of shit, i get 11/hour. but at the dealership, i would have been getting paid at 18.75/hour flat rate. too bad i got fired.

Holy crap I thought all smog techs would at least get paid like 15 bucks a hour. 11 bucks a hour is horrible.

yeah, my boss is a bastard. but i need the money, and its easy work.

[joefresh]

how much does your boss want for the q45?
also, i would like to install a "heavy duty" type engine in my vehicle. will this be a problem?

heavy duty these nuts joe. mike is a douche canoe and left since its slow, and im just doing nothingz

[blitzsti22]

^^^nope i dont got a buddy with a ecu all my buddies have hondas :/

Is it true that sex in the car puts bad juju on it and I won't be able to pass smog?

yes. the anti sperm sensor in the cabin goes off and turns on the check engine light. the computer will see fail and aids, and immediately stops the dyno so the car is crashed into the wall. then it fails it.

Yo I can't believe you're still up!

There's some great info in this thread.

So my spare car's a '91 S13 with an OBD2 KA in it... as long as the engine passes the sniffer test and visual, they're not going to try and plug anything into it to read codes? Basically, I can just pull the CEL bulb and be straight? What about at the ref?

Also, girlfriend's car is an out-of-state model... can I buy a 49-state cat off the 'net to pass smog here, or do I need a special CA 'absorber' cat? Where should I go to get one? She's got 100k on a 2001 Sentra and it threw a code, mechanic she took it to said replace cat and o2's?

+1 to this... "astute" techs will notice that the CEL doesn't come on when the car goes through the self test... notice when you first turn the car on all the warning lights come on... this is so you can check if the bulbs are dead. wiring up the CEL to the oil light works great because it will come on with the self test and then go off once the car is up and running.

There are things you can do to the Auto ECU to prevent it from throwing a code, I haven't done it but I've heard its not too difficult, Manaul ECUs go on eBay and the BST all day for $60...

not sure what years yours is but there's a nissan sticker on it with two big letters cross reference those to figure out what it is

Automatic ECUs
11 = 89-90 240sx AT (KA24E) ?
15 = 89-90 240sx AT (KA24E) Cal
25 = 91-94 240sx AT (KA24DE) ?
29 = 91-94 240sx AT (KA24DE)
HU = 95 240sx AT (KA24DE) (mfg before 10/94)
3D = 95 240sx AT (KA24DE) (mfg after 9/94)
CB = 96 240sx AT (KA24DE) Universal
NF = 97-98 240sx AT (KA24DE)
J7 = 97-98 240sx SE AT (KA24DE) (A18-H64 GA4)

Manual ECUs:
10 = 89-90 240sx MT (KA24E) ?
24 = 91-94 240sx MT (KA24DE) ?
28 = 91-94 240sx MT (KA24DE)
HT = 95 240sx MT (KA24DE) (mfg before 10/94) (A18-E07-G90)
3C = 95 240sx MT (KA24DE) (mfg after 9/94)
CA = 96 240sx SE MT (KA24DE) (A18-E27-G46)

^thats a list I've been working on, it's not complete so if you've got something else then you'll need to google about. My car has "HU" because it's an early model 95 with an AT ecu...

i know i know off topic but was wonderin sorry to kill thread
was wondering mine has a EP on it and mine is manual 93 ka24de is there anyway to confrim this ecu actin all wierd

on your s13, no, theyre not gonna plug the smog machine into the ecu. as long as it passes the visual check engine light test (aka the check engine light is unlit) and it passes the normal visual and sniffer test, you should be cool. i dunno about the ref though, those guys are crazy.

out of state model cars are only required to pass the federal emissions test, which usually is just lest strict. its still the same test however, just the limits are a little bit higher. im guessing the code was "catalyst threshhold below efficiency" or some shit like that? that code usually goes off when the difference in the front 02 and the rear 02 is not what the ecu sees. so it could be just the cat, or just the 02 sensors. or both.

slow as hell right now. but we average about 16 cars a day. one day will have like 10 cars, the next will have like 28

[Oo_Skyline_oO]

I love my S13, no obd check and yes indeed +1 to the guy that suggested to wire the check engine light to the oil pressure light, GENIUS!!!!!!!!
