I Just wanna know if is it ture. if an evo install a standalone, so she will never pass the emission test right?

 

i do think so

 

if they connect and odb II connector it will fail

if its just the tailpipe test i guess i can pass

I dont know anything about emission testing though

 

You cannot pass with the stand alone still connected. However, switching back to stock ecu is very easy. What I am doing, is having stock ecu reflashed through the mail, which is easy since I don't have to worry about down time. Then just plug in stock ecu and the MAF sensor, unplug the MAP sensor, and if applicable plug in the stock O2 sensor and you're good to go. It's really not that big of a deal.

 

It depends on the level of mods you have..

If your state requires OBD-II for it to pass then it cannot..

If its a sniffer check and some minor visual checks, then its possible to tune the car so it could pass, but you **HAVE** to run a catalytic converter no matter what.

However if you plan on swapping your ECU and Standalone, you'll need to have your ECU reflashed for your mods, AND also be certain that the flash can pass an idle emission test (cams and injectors can make that difficult) Plus you would have to undo any mods that will trigger CEL's which can limit your mods.

 

If you live in California, it doesn't matter. You don't have to get your first smog test until your EVO is 6 model years old (new law effective 1/1/05). By then my RS will be a melted hulk of metal.
