You left the SES box checked.
And even if you remove the SES box it will still show up as a permanent code that doesn't just vanish when you disable it. It'll stop the engine light from coming on but will still show up when you pull the codes. Maybe after a long time it'll go away but maybe not.
You also didn't disable the catalyst test in the exhaust tab. Plus you left cat over temp protection enabled, disable that.

If you don't post your tune and logs when you have questions you aren't helping yourself.
I should un check the box? cant find cat over temp protection?Originally Posted by 5FDP
Yeah, uncheck the SES box if you don't want the engine light to come on.
Cat over temp is in the engine tab > fuel > temp control. COT is the table.
