Banks Power Dodge Trucks: (Diesel ’98 - 02 5.9L Cummins ISB) PowerPack & Stinger-Plus systems (connects to pump wire) - Manual (Page 23)

Go over the entire installation as a
precautionary check to ensure that
all clamps are tight, wiring and hoses
are properly routed, and connections
are tight. Start the engine and allow
it to warm up. Drive the vehicle
under light load (normal around-town
driving) for 20 to 30 minutes, and
listen for any exhaust leaks or rattles,
or intake boost leaks. Shut off the
engine and re-tighten all intercooler
and turbocharger boost clamps. These
connections may have loosened
with time, and if leaking, will cause
a drop in boost pressure with a loss
in performance. Check that clamps
are properly positioned on hoses,
and periodically check tightness of
hose clamps at regular maintenance
intervals, such as when the oil is
changed.
Observe the operation of the boost
and pyrometer gauges while driving
under varying conditions. Turbocharger
boost pressure will increase as a
function of load and engine RPM, thus
the engine will produce little boost
while cruising at light throttle, with
maximum boost while climbing hills
heavily loaded during acceleration.
Note the boost level seen during
hard acceleration with a given
load. If performance seems to have
deteriorated sometime in the future,
the maximum boost figures may be
compared to see if boost has dropped
off. Lower boost may be caused by
turbo ducting leaks, a malfunctioning
wastegate or fuel injection pump,
or dirty air filter. Typical maximum
boost pressure settings for the Dodge/
Cummins diesel will vary considerably
with stick or automatic transmission
options, year model of vehicle and
altitude.
Use your pyrometer gauge to
monitor exhaust gas temperature
(EGT) in the engine. At idle, exhaust
gas temperature will be very low,
perhaps only 300°F. As the engine
is accelerated for higher speeds
with greater loads, the EGT will rise.
The highest EGT will be seen under
maximum load at full throttle, such as
climbing a steep grade with a heavily
laden vehicle. Your pyrometer is color
coded to assist in your reading of
the gauge. The red zone indicate a
dangerous level of temperature. Your
engine should not operate in this
range for more than a few seconds.
The blue zone indicates when it is safe
to shut the engine off. To avoid heat
damage to various engine components
it is recommended that the exhaust
gases cool below 400º before the
engine is shut down.
Your OttoMind is calibrated to
maintain a maximum EGT of 1300°F.
You may experience brief excursions
slightly above 1300°F under
acceleration. This is normal and EGT
should return to at or below 1300°
within a few seconds. If you find that
EGT remains high for any length of
time, check for boost leaks or a dirty
air filter.
If you feel that your OttoMind is not
functioning properly, some diagnostics
can be performed. Remove the
OttoMind from its mounting location
while keeping all three connectors
plugged in. Observe the two LED’s
mounted on the programming port.
The upper left LED will indicate red
when the key is on. Once the engine
is started and idling, the red LED will
go out and the upper right LED will
indicate green. As load increases,
the red LED will progressively grow
brighter as fuel delivery is increased.
If LED’s do not indicate as suggested
check all connections to ensure that
they are proper.
