Hello Folks,
First post here.
I have a 21 LT1 and am swapping over to flex fuel. Have installed the sensor and work as a GM Engineer so good there
Question: Where does the Mult4 table come from below? I have looked in both the internet and this forum and nothing to compare to.
Thanks in advance!
Erick.
