the AED RPM Clamp allows you to limit the effect of the AE algorithm at certain RPMs. AE is not normally needed at higher RPMs, hence the below example table is typically used to have full effect at idle and up, then taper down to 50% effect (0.5 in the table) as RPM increases. It is a multiplicative modifier to final computed AE VE added. For more details on AE please this section.
