CHECKING ENGINE PERFORMANCE
The Six-Gun/EconoMind Diesel
Tuner requires the engine coolant
temperature (ECT) to be above 110º
before it will add fuel. If the optional
Banks IQ or DynaFact
®
gauges are
installed, 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 EGT gauge(optional)
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.

If the Six-Gun/EconoMind Diesel Tuner
has been moved to a different vehicle,
or you are instructed to do so by
Banks Technical Staff, it is possible to
reset all of the parameters that the
Six-Gun/EconoMind has ‘learned’ -
presence of an EGT thermocouple or
Speed-Loader, etc.
CAUTION: The following procedures
can only be carried out with the
engine OFF!
1.
Turn the vehicle key to ON but
DO
NOT
start the engine.
2.
Fully depress the throttle pedal and
then release it completely. Repeat 5
times. The GREEN LED will flash when
this is completed successfully.
3.
Turn the key OFF. Wait 30 seconds,
or until the GREEN LED goes off and
stays off. Turn the key back to the ON
position but
DO NOT
start the engine.
4.
Fully depress the throttle pedal and
then release it completely. Repeat 5
times.
