gents
I've got a crate motor LS3 with Comp 54-469-11 cam, holley highrise intake and 102mm TB. I'm having some issues with the MAF tuning that I can't seem to figure out. I'm tuning in OL and using the AED WB.
When tuning the MAF at highway speed, or when i'm in 4th gear, my EQ ratio is pretty good (-1.5 to +1.5 there abouts when averaged). The problem that I'm having is in the lower gears when I'm traveling 15-30mph. At these speeds my EQ ratio is somewhere between -8.0 to -11.0.
I don't quite understand why it changes so drastically in a lower gear?
The second issue that I'm having is also with the MAF, between 4350 and 4650 Hz (EQ ratio is -1.20 -1.06 and -1.09), while the airflow in g/s is 42.3 51.7 and 48.0. What would be causing such a spike in the airflow?
If someone can have a look and help point me in the right direction, I would really appreciate it.
