DESCRIPTION & OPERATION

Figure 7 — Heat Shields (with Left-Side Mounted EECU)
V-MAC III
The V-MAC III engine control system has been
developed specifically for the E-Tech™ engine.
Features include electronic drivers and
diagnostics for unit pumps, separate engine and
vehicle control units, and a revised wiring
harness. These features make V-MAC III
applicable only to the E-Tech™ engine.
V-MAC III ELECTRONIC CONTROL UNITS
The Engine Electronic Control Unit (EECU) is
located on the right side of the engine (Figure 8)
in early-production engines. Characteristics of the
engine design, such as heat shields, vibration
isolation, and running low-pressure fuel through
the EECU mounting plate (to cool it), permit the
EECU to be mounted directly on the engine in the
right-side location.
