How does the PE system in OEM LT computers work/ Been so long I cant rremember. Doesnt use a whole ratio PE enrichment like LS where 1.20 in PE means Stoich/PE (14.7/1.2)=12.25 target AF
They are usually 0 or small neg or positive numbers, so id assume its a modifier over something like the Open loop AFR vs Load vs Coolant Temp table in LT1Edit (unless its something we cant see?) Positive numbers make it richer though which I find off if its a simple adder
So Say at temp and load your in OL is 12.0, and have 5% in PE means itll target 5% richer? So 11.4?

GM OEM ecu uses the logic, so thats applicable for lt1edit or tunercats, thank you
