Getting past Emissions with catless tbe
Hey guys,
I am in serious need of some Emissions test advice with my Evo 8.
Some specifics: I drive a 2005 Wicked White Evo 8, About 2 months ago, I put on my megan racing tbe system. My car has an Injen intake, Injen upper/lower IC piping, and of course the megan racing tbe which I just mentioned.
Last week I received an Emissions test notice. I went to my buddy's shop who has this OBD II bypass device that hooks up to the OBD II and erases codes to get rid of a check engine light.
After the code was erased, the check engine light went away and I immediately took my car to Emissions. Thankfully, the check engine light did not come back on as I was told the code can come back and turn the check engine light back on randomly.
Unfortunately, when the Emissions lady hooked up her computer to my OBD II, her computer was unable to read my car's codes (because less than 20 minutes before hand, I had my friend erase the code that had the check engine light on).
I just played dumb and told the lady I had no clue why it wouldn't read my car correctly. Little did I know, that device that my friend used, completely erased ALL codes in my car...Therefore I need to go back to the Emissions and get tested again before mid December.
This leads me to my main question. How do you guys pass the Emissions test on your Evo's with modified exhaust systems?

the emissions computer has the ability to detect if you reset your computer before the test. there are monitors in your car and you are only allowed to have 2 in a not ready state in order for the test to complete. when you reset the cel all monitors go in a not ready state until you complete the drive cycle to set them to a ready state. hope this helps good luck.
You reset the readiness monitors. The car must be driven for atleast 50 miles before everything is once again set.
Having a TBE and a CEL on is most likely a P0420. Buy yourself a o2 sensor spacer, drive the car around for a week and go back.
You could have told her you just replaced the battery, or had the battery out of the car to fix something. By disconneting the battery, it too will reset the readiness monitors.
There is a certain way to drive the car, which, IIRC you go WOT for 8-10 seconds and let the car coast for another 8-10 seconds, and the cruise at about 60mph and it should reset the monitors within a couple minutes. I understand WOT for 8-10 seconds in an Evo can put you at some very illegal speeds, but we are usually doing this in Civic's, Accord's, etc. I have my PA emissions and safety inspection lisences. We usually just give the car back to the customer and tell them to drive it and come back in a few days. But if we have to drive it we use that technique. OR, some of those little scanners will read live data and you can drive around and find when all your monitors are complete. By just drive the car around, it once took me 60 miles to complete all the readiness monitors...
