I am tuning a 2014 p51 vette auto with cam and headers . after about 1 minute of idling it goes into open loop and comandes 11.7 afr ,the fuel pressure state
changes from hot fuel to cold engine . Does anyone know how to stop this ? this is happening at operating temp .
Cat overtemp??

I figured out why my open loop command is occurring .
when the cam was changed the dod was removed .There were a few codes that were not shut off relating to dod .
I am not sure what dod codes have to do with fuel states or a 11.7 afr command at idle .
