I'm working on acceleration enrichment settings, however I couldnt find more information about PW Adder as enrichment method. Previously I was using PW multiplier but AFR was very lean under acceleration. Only by changing to PW adder using pretty similar settings response was much quicker and AFR between 12 -13. However I would like to know exactly which is the difference, which method is recommended.
I'm not sure if PW multipler will multiply a defined PW or will add the value to PW. So my question is which is the main difference between PW multiplier and PW adder so I could proceed properly in the way I propose my settings.
