Does changing the firing order in the tune not work. Ended up having to swap pins at the ecm. I thought changing it in the tune worked in 2.24.

Firing order in tune is for misfire recognition. You have to manually repin the harness, then set firing order in tune so misfire monitor correctly identifies the correct cylinder in the event of a misfire
