SR in obd2 car (emmissions related)

[goldollar]

Is anyone running an SR in a OBD2 car, and if so how did u overcome the check engine light from comming on and what not, because in ga you cant pass emmissions if ur check engine light is on.

[goldollar]

Anyone

I am running a redtop in a 90 s13 f/b. I am using the 180sx gauge cluster, and the cat light is always on. I am also running a test pipe, but I thought since it was obdI that it wouldn't have a cat light.

yeah i was akin caus im i thinkin about buyin an s14, but i dont wanna heve to trogh a bunch of troubles tryin to get the car to pass emissions once i do the sr swap. I just tryin to see if it would be better to get an s13 instead, but i reqlly want an s14.

It won't pass. The governments computers will not interface with the SR ecu. If you really want to do the swap on an S14 then get a 95. They only have to pass sniffer.

Thanks thats just what i wanted to know.

Yeah, I know this is an old post, but I would like to know more of what yall with OBDII did to pass emissions. Im in Illinois by the way so I dont have to worry about Smog and CARB.-Firstly, assuming that the OBDII jack is still present after a SR swap and it doesnt read correctly, do they kick you out or move on to the dyno? -If you pull out the jack during the swap, don't they have to dyno it or will they just look up the year of the car and figure out that it should have a jack and flunk ya?-Or do ya have to roll up to testing with a few bills, and bypass the system?

This is kinda my deciding factor tween performing a SR swap or rebuilding and turbo-ing the KA. I already have a '96 so I am not about to sell her and buy a '95

Thanx, In advance

Some states are different, so this is pretty much for GA and probably California. Most of the laws are pretty much the same. If you fail the OBDII test you have no recourse. You cannot just pass sniffer. The only exception to this is that for some reason the states computers have failed cars with no codes and that communicate well, but it just likes to fail them. In which case they have to go before the ref and prove that everything is good. As far as paying to pass, I don't know that you can do that. I don't know how complicated the states program is and if it can read the cars info from the ecu. Someone from Cali, GA or somewhere else may have payed and you would have to ask them.

As far as building your KA. You won't be able to get a reprogrammed ecu as I believe they do away with most of the code that makes it OBDII when they reprogram it.

Basically the 1997-1998 240SX's are OBDII. So if you want to just go through regular emissions get an older S14. This is how it would work in WA, sounds same in GA. CA is not lucky enough for this cakewalk.

If you are worried aout obdII and you want a turbo you might as well get the greddy kit. It is supposed to be obdII legal. Thats what I'm gonna do sometime soon. Texas is really gay about emissions too.

[SpeedRacer1]

Sure the Greddy kit is legal. But this is the SR20DET forum. The SR20DET is not legal for road use in the US. Also the Greddy kit is for the KA24DE, so its not applicable in this case.

[threelongyears]

and the greddy kit is only carb exempt for 95s(obdi) only. sorry for more ka talk.

[driftercs13]

on an obdII car the computer actuually has a series of codes that it send to identify the vehicle so there is no way to as some would say smoke a obdII car. and just so you know i live in GA and i'm a state certified emissions inspector.

[yellow_jacket]

And just think, more and more counties and states are going to do the OBDII testing.

[Nismo_Freak]

The "cat" light is an exhaust temperature light, not one for the catalyst operation (the ECU would need 2 02's to know this).

96+ are all OBDII ... 95 was the first year of voluntary acceptance, 96 is the first year of mandatory acceptance.

As far as paying to pass, I don't know that you can do that. I don't know how complicated the states program is and if it can read the cars info from the ecu. Someone from Cali, GA or somewhere else may have payed and you would have to ask them.

eh .. i don kno how to quote but here in CA i kno places that if you pay a bill or two theyll pass you

[Phax]

To pass an OBDII car in CA, you need to find someone else with the same year, same car that you have and smog that. There is no way to pass an SR20 ECU through the CA system. Part of the OBDII process is to interface with the ECU. I'm not sure what data they might pull out during the test other than RPM and speed.

Even if you can find a place to pay, odds are they won't be cool with smogging a car that doesn't match the VIN on the print out from the state. I haven't found one yet.
