CHECKING ENGINE PERFORMANCE
the Six-Gun/EconoMind Diesel tuner
requires the engine coolant temperature
(ECt) to be above 110º before it will
add fuel. Observe the operation of the
boost and pyrometer (EGT) gauge values
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 will
vary considerably with stick or automatic
transmission options, year model of
vehicle and altitude.
NotE: Before key-off, check tuner for
error codes.
Use your Banks IQ 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.
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 Six-Gun/
EconoMind Diesel Tuner is calibrated to
maintain a maximum EGT of 1350°F. You
may experience brief excursions slightly
above 1350°F under acceleration. This is
normal and EGT should return to 1350°F
or below 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.

TROUBLESHOOTING
If a Tuner has been previously
installed, verify that the Tuner has
the latest version firmware. Check
your version to the current version
available on the Banks website.
SpeedBrake may not function
properly if Tuner/SpeedBrake
firmware is not up to the current
version.
For PowerPDA, use PowerPDA
manual for TroubleShooting
instructions.

Troubleshooting (Using The Banks
iQ)
check the Banks iQ’s Status indicator
for the “OK” icon on the upper left
corner of the iQ screen. Any Tuner fault
will be indicated by the “Banks Engine”
icon (see Figure 34) and its cause can
be investigated by running a ‘Tuner
Diagnostics’ from the Diagnostic menu.
