Heatsinking, Chryslers

[Chad Clendening]

In addition to using the inlet air to cool the power drivers, the Chrysler's use a switching pre-regulator to make a 7.5 to 8
volt power supply.  This setup not only allows the linear 5 volt regulator to operate with minimal power dissipation, it also
allows the ECM to operate with 4 to 5 volts at the battery, probably well below the limitations of other EFI components.
