EBL NAlpha tuning?
Hey guys I was wondering what exactly do the NAlpha tables do? I was wondering what would happen if I smoothed them out. I was checking out my MAP KPa vs RPM & TPS and those tables look a little dicey. What can I do?

Re: EBL NAlpha tuning?
In your case they should be (are) doing nothing.
They are only used when running in N-Alpha mode.
Play with them all you like, just don't turn them on.
N-Alpha is to remove somewhat the MAP sensor's contribution from engine fueling, used only when true MAP readings are not usable.
Enabled with Option Word 1 bit 7.

I see, what benefit would there be to use this mode?

Re: EBL NAlpha tuning?
You could use N-Alpha if your MAP sensor provided unusable reference,
or there was no MAP at all.
It's benefit is that of a workaround, something you might have to use if say a very radical cam were installed.
