best COBB map for Emissions test, ontario canada

satelliteguy · 01-02-2011, 11:40 AM

Hey,

I have 2004 wrx with catless up and down, and catback, sti pinks, vf39, no flaps on tgv and short ram intake tuned with the cobb AP.

Have to take it for emissions test, just wondering if there is a better tune to use opposed to the regular one?

I will be putting the factory catted down pipe back on for the etest.

I am located in Ontario, canada

(location included, sorry unabomber)

For what it's worth, I posted in the Ontario forum somewhere, and a guy there passed the sniffer here with just a single high-flow cat. Just make sure you give it a nice 20 min drive before you take it and they test it right away... I think the limits are fairly lax. Good luck.

I'm curious what others say as I just got myself an AP (haven't even installed it yet).

yeah hopefully the 2 factory cats cut it

they only have 35k miles on them

If you have both factory cats you'll be fine as long as the front O2 sensor is good and you don't have other mechanical problems (low compression, vacuum leak, whatever). Cobb vs stock won't matter much because they are both going to be running in closed loop. With a single high flow cat is that you have to be more concerned about keeping the cat warmed up. The stock two cat system works better at lower exhaust temperatures.

yeah engine is in pretty good shape, so i doubt anything mechanical.

i have no idea about the 02 sensor though.

what would be the symptoms of a failing one?

arghx7 · 01-03-2011, 11:08 AM

well it would throw a code...

satelliteguy · 01-03-2011, 04:57 PM

I thought so, I have no active or inactive dtcs so it should be good.
Also Ill post results after I get the test done, in case anyone else requires this info.

ETEST results.

So, in reality our cars comply with Ontario's emission standards without Catalytic Converters!! Wow...

The dilution number worries me a bit. My car is stock. I'll have to compare my last test results to yours to see how much of a difference the Converters really make.

Thanks for posting the details.
