This is from a mazda 3 bin

I'm trying to figure out what this table is. I believe its ignition?

Its a 16 by 30 table.

The code looks up the cell value
then multiply by 0.0005
then divide by pi (3.14159...)
then multiply by 0.5
then multiply by 1999.0
then places the value in memory

I'm a little unsure how to scale this to advance....

My thought is that there are only a few sensors looking at rotation.....

what do you guys think?

How did you come across this .bin?

Is it a stock rom that you downloaded from your car?

It looks like VolumetricEfficiency against throttle openning and RPM.

Such a table is used in AlphaN setup.

-500 is probably 0%, +1500 is probably equal to 100%
