MAF Adder for Tephra V7 found.

I really needed to change my MAF Adder because my MAF Scaling was at its limit.
I started up IDA pro 5.5 and started labeling every thing... Then i found this.

This is from 96532706!



If any one wants the XML for ECUFlash it is.

Code:
<table name="MAF Adder" category="Global Fuel Settings" address="1512" type="1D" level="3" scaling="uint16"/>
If I keep labeling what I know from definitions, I may actually have something to contribute soon. I'd rather start a new rom from C++ but that would probably be more trouble than its worth (not to mention poor performance due to programming bugs, and possible engine damage and bricked ecu).

Keep im mind that the Scaling in the default XML includes this value already! Make sure you offset your numbers, or create a new scaling that is just the values from the table (not added the 140).

The MAF Compensation Scaling (aka MAF Smoothing) table can double the stock MAF scaling.

What is the formula for that?

MAF = MAF Scaling + MAF Adder + MAF Smoothing?

MAF = [MAF Scaling + MAF Adder] * MAF Smoothing * A bunch of other stuff
(check Mr. Fred Advanced Fuel Control thread)

Scaled as percent 128

I am trying to do this for my car currently as I am seeing afrs in the low-mid 12's with the actual high octane map pegged max rich (7.4:1). I am trying to adjust my MAF as I have a larger AEM intake but cant find an actual how to of putting in a scaler. Can someone help me out on this?
