anyone else done an LS swap and had several evap/emissions codes afterwards? Im not sure if they effect anything but would be nice for peace of mind when trying to tune to know they are out of the picture.
ive got P0443, 0449,0452 evap codes that come right back if rest.

So is it just a matter of deleting them in the pcm

Also have TCC codes and im running a THM250C transmission so i need to delete those too

Some mod delete this because he asked the same thing in the LS Swap section and doesn't want to listen to those of us who are the experts.
are you drunk? this is not even close to the same questions and you didnt even read what i originally posted.
the OBDLINK software said those exact words.
"Operating in open loop because engine not up to operating temp"
