Can I use a obd1 ls ecu to smog a JDM GSR motor OBD1 also? I dont have money to buy a US spec ecu right now

 

I really dont think so... Esepcially for smog.. dont they check all that **** out?

have any friends you can borrow one from?

 

only friend that has a teg is obd2

 

Use the OBDII to smog....Thats what I did and then covert back to the OBDI for performance if thats what you are looking for...

the obd2 ecu requires more sensors and stuff to work.. I dont think that would work...

For example, you need 2 o2 sensors instead of only 1.

thats what I was thinkin

 

up to confirm

 

 

Just ask around man. There are people out there for an extra 50 bucks will smog anything that drives in front of them. look around for someone who will do it no matter what.

 

I might have to. But does anybody know for sure if I can run the ecu w/out motor probs and if itll pass smog?

 

Im still sticking to my answer of no..

The gsr has butterflies, the ls doesnt.

Also, the whole vtec thing.

Especially since it's getting smogged..I really dont think it's gonna work.

 

i dont think a usdm ecu will pass with the jdm motor.
i believe the using the us ecu will throw a check engine light because it will look for the evap? not sure.

 

bump... i got a jdm motor also and need to smog in july.. i heard the LS ecu might work but not sure.. inputs from experience ppl plz........ not ppl that THINKS this and that

 

if u run into a smog tech that knows his blocks it work won't no matter what ecu u using. its a jdm block, the stamp will give it away. as far as emission goes it might pass, just not the visual.

 

o man i remeber the stress over smog when i used to live in cali now i live in nc and no smog!! i went to the inspection with turbo and everything all they care here in nc is safety no smog i love it hahah sorry for you that need smog i no how it feels it sucks! good luck dude

 

^^^^^ exactly what i was thinking.


and at least I'm trying to contribute to the thread.
I gave my opinion, and a very logical explanation as to why I thought what I did. so why dont you try to give some advice instead of ridicule the people thjat are trrying to help??

a nonvtec ecu in a vtec car will not run right. Its as simple as that. With as strict as cali's policy is for smogging, its an extremely, extremely small chance anything good will come out of it.

Good luck with finding a good ecu.

 

well everyone basically explained it out its simple a non vtec ecu wont run right with a vtec motor but i did run a ls ecu in my d16z6 vtec once just because my p28 was chipped for turbo so i ran ls ecu just till i got my other chip in but it ran ok but vtec didnt engage but for smog it wont pass sorry dude get a gsr ecu

 

thanks guys and my ecu worries are over! I got the right ecu NOW
