Introduction
Factory Specifi ed Parameters and
Features
Each new engine will come with several features set
at factory default settings. Some of these, like the oil
sump capacity, are set at the engine factory. Others,
like the tachometer calibration, are set by the truck
manufacturer. All of these default settings fall into one
of three categories.
1 – A specifi c value required by the engine or truck
electronics for proper operation (example - oil
sump capacity, tachometer calibration)
2 – A standard value set for convenience (example -
PTO Ramp Rate is set at 50 rpm/sec)
3 – A value set at the upper limit of the possible range
to ensure that the specifi c feature does not take ef-
fect until reset by the customer (example - Vehicle
Speed Limiting is set at 127 mph)
