reason i ask cause im curious on the process of fuel tunning.

say i have a long level straight closed road(traffic free)

if I was to do a 3rd (or what ever gear) pull and tune a SAFC2 to a good AFR(using AEM eugo) across the rpm's whould this tune yield the same AFRs in all gears? cause its not like you can tell the safc to correct for different engine loads so i would assume so.

now i know an SAFC isnt the best tunning device for a rb but im just curious as to how the process of on road tunning would be done.

Yes it will have the same AFR in all gears. The Fuel Mapping is all based off Load, RPM, and Airflow.
