i cant reallly find any information on the AFC accept for the hack. what are all the different things for? and how do i find out how t use them. on the wide band Hvt graph, it apeears that making the numbers lower richens the fuel miture, and the other way leans it out i guess? and the ne0v stuff i have no clue what it is, and the instructuions only say how to change them, not what they are for.

how are people tuning these on NA cars and geting 10 whp???!?

thanks

 

Try carefully reading the instructions again
