I searched for this and didn't really find a conclusive answer but I think this is the reason for me running so lean on V7.

The Airflow/Hz Raw Scaling on my oem map compared to my Maf Scaling (Maf adder already included) are very different. Obviously I'm missing something here since it says maf adder is included.

How off should the values be? For instance in the 1610hz cell my oem tune says 232 and the tephra cell says 466.5.

All my fuel/timing settings look spot on in comparison, so I'm hoping whatever is here is why my car runs so lean now.

 

it simply includes the maf adder which i believe is 160 or 140... i forget and im too lazy to do the math lol

 

So then if my oem tune says 232 I add 140 so that value should actually be 372 not 466.5?

 

ok on you oem map open up the maf scaling table
then open it up on v7 as well
now go to edit > edit map definition , the top you will see scaling set to " maf scaling plus adder "
change that to " uint8 " , what that does it let it read it like a non v7 format. now copy the oem / maf scaling that ran properly into the v7 maf scaling and change it back to " maf scaling plus adder " in the scaling drop down list.
if you still cant get it let me know ill put up pics so you can see step by step

 

hell ill add it any way just in case some one else needs help and a visual is better than verbal

** edit:
i would advise you to change it back to the v7 back to the "v7 style" once your done though.

 

I actually had this same question! hehe

What exactly is the maf adder tho?

 

When I changed it to unit8 it went identical values as my stock map.

So then this isn't why I'm running so lean. Sigh.
