Default 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?

You tuning LT's again? You might be able to get some info from Ed Wright. He checks in every now and again, or e-mail him.
