Will I notice or run into any issues if I leave my emissions DTCs such as EGR, AIR and etc. as SES "Checked" with 'No Error Reported' VS. SES "Unchecked" with 'No MIL light'? ... Essentially isn't the outcome the same or am I misunderstanding something?
If you aren't running those parts just set everything to no error reported with the SES box unchecked. That way they won't appear when you read the codes even though the check engine light isn't on.

If you don't post your tune and logs when you have questions you aren't helping yourself.
The only thing ive noticed checked vs unchecked is of you have it unchecked it may not make your ready monitors auto ready. But havent 100% confirmed this.

That's how I had it before but I was just curious if I'd notice any performance issues going into the future if I just left them as checked and No error Reported. ... It'll take me 30 seconds to uncheck them so I'm not worried about it. This is more of a "What If" question than anything else.Originally Posted by 5FDP
Oh .. I guarantee you that the readiness monitors won't show complete if I un-check the corresponding DTCs. ..lol .. I confirmed it. Big bright "NOT READY" in red or it shows something not installed when according to my VIN, it should be present. .... Basically, I'm done with the emissions stuff at this point. I'm just wondering if there's really any point in un-checking the DTCs.
