Alternator charge current map?

Alternator charge current map?
I just installed a new HO alternator and it seems like I'm not getting the full power out of it that I feel I should. I noticed in Merlin's Ecuflash tuning guide that there is an alternator charge current map but I can't find it for the life of me in ecuflash. Anybody have any idea where I might find it? Merlin's guide page 123 section 10.12 if you want to see what I'm referring to. Thanks

I could be way off, but I was looking through the auxiliary engine functions portion of the code and I may have found the tables.
96530006
Alternator Charge Current: Sub_19EC0
Values: 4655
Engine Speed: 6940
Engine Load: 695E
I have it labeled as an unknown PWM output that can be logged through MUT8E.
G-Terminal Dead Zone: Sub-21354
Values: 46B6
Engine Speed Axis: 664A
Log through MUT8F

Roadspike. A few pages ago I offered you my vehicle to test your SD maps. I guess maybe you didn't see my post. Pm me I'd you're interested.

4xforce, what rom # did you want the charge map for and I will see if I have its address.

Looks like I have the right table, but my load is different. The load axis looks to be based off some other load variable?
Anyway until somebody knows the correct load variable, here is what I have.

^03whitegsr, I really suspect your load and rpm scale is correct, I used scaling from an Evo6, found a couple of years ago.
This snipit uses 03whitegsr's scaling

<table name="Load" address="6f7e" type="X Axis" elements="9" scaling="Load16"/>
<table name="RPM" address="6f60" type="Y Axis" elements="10" scaling="RPM"/>
</table>
<table name="Alternator G Terminal Dead Zone" category="Alternator" address="4114" type="2D" scaling="AltDeadZone">
<table name="RPM" address="6b7a" type="X Axis" elements="10" scaling="RPM"/>
