I have a 2000 Chevy Cavalier LD9 engine that I have put into my 1930 Ford Model A
I am new to HPTuners.
I am tuning it and have come across an area under "Airflow" and "Main VE" that is labeled "Low RPM Double Fire"
I am hoping someone can tell me where this would come into play when tuning?
I have added a pic here of the screen. I hope it came through

Any input would be appreciated
Thank you
