I'm just about to go through emissions testing here in Oregon for the first time since adding long tubes and UpRev. I didn't turn off any sensors myself, and I have the Cajun catted b-pipes. There is no visual inspection here, so I'm not worried about that, but will the UpRev software cause any issues once they "plug in"?

Doesn't bother mine... and they have passed me with UpRev for years now in PA.

If you're concerned, set your UpRev setting back to "stock" before bringing it in for testing...

I think my last trip into the emissions testing station was an OBD-only test. It was way to quick for them to have connected the sniffer and run the engine through its paces. So they didn't see anything in the computer that they didn't like.

Awesome, thanks for the replies. I just didn't know if the OBD test would detect the non-stock ECU flash and cause problems, but sounds like you guys have been through with no issues. I know each state is different, so hopefully everything is good to go.

Just be sure to not reflash back to stock or pull the battery cable within 100 miles of getting tests done. The ODB2 check is to see if the the emissions are in ready mode or not and to see if there are any detected emissions codes.

+1 what RB said. Just the tune/ uprev software will have no impact on emissions testing, the only reason you would be flagged was if codes were disabled in the tune--this causes the O2 monitors to show up as not ready forever

Every time you reflash the ECU or disconnect the battery the ECU has to cycle through its readiness checks before the O2 monitors switch to "ready".

Thanks, RB and seymore. Excellent timing?I just replaced my battery tonight! So I take it I need to go put 100 miles on it to "ready" the sensors before I take it in?
