V-MAC Co-Pilot Operator's Manual 63
To change operating parameters, a computer is used and requires that it is running
the VCADS software. In addition, a datalink adapter is also required as an interface
between the scan tool and the vehicle management and control (V-MAC) IV system.
Note: If the rear tire sizes are changed, or the rear axle ratios are changed, you must
contact your local MACK TRUCKS dealer. Failure to notify your local MACK
TRUCKS dealer of these changes may cause inaccurate speedometer readings.
Cruise 'N Brake Engagement Delay
With the cruise 'n brake engagement delay feature, engagement of the engine speed
(RPM) is delayed in cruise control to reduce engine brake cycling. The brake will
engage 3.2 km/h (
2 mi/h ) above the cruise set speed. The engine brake operates
normally when cruise is not being used.
Engine High Idle Speed if Stopped
Maximum engine speed (rpm) can be adjusted by using VCADS software. The
possible high idle settings range from 600 to 2,600 RPM. However, the engine speed
will not go below low idle and will not exceed the OEM high idle (usually 2,100 or
2,150 RPM).
Engine High Idle Speed in Upper Gears
Sets the maximum engine RPM if the gear ratio is less than 1.5. This feature is
intended to improve fuel economy by limiting efficient high speed engine operation.
