Motiv Flex Fuel Installation Guide

New FlexFuel Box and harness received from [email protected]
i hope i can test it soon (after reflashing FF map) but i don't know when because of bad weather (no garage) and pandemic situation.

According to mhd my ff voltage is still 4.05v even though none of the FF box or harness is installed.... How do I fix this? I want to maybe flash back to stock then to the FF v82+
