IMPORTANT ALTERNATOR CONTROL

In order to control the 5.7/6.1 Hemi alternator, Hemi pin 16 must be connected to Infinity pin C1-2 (LS5).
The user must then configure the 2D table named “LS5_Duty [%]” for proper alternator charging.

Below is a baseline table that will allow basic alternator behavior. Higher duty cycle yields higher
alternator output.
