When tuning 7747 ECM VE tables, VE 1 is used from 0 RPM UP TO 3,200 RPM correct? If i understand correctly, VE 2 is added to ALL VE 1 values. So IF I am correct I add VE 1 values and VE 2 values together for each individual cell(S) hoping to not reach 100% VE? I will stop there for now. If anyone responds I will then pick up where I left off asking more about the subject such ass what I believe is a formula but I am not exactly sure.

EDIT: I have looked at the 7747 prom tuning guidebook section, good info. I am more familiar (not by a whole hell of a lot) with TPI & LT1s. Thanks all!
