The Six-Gun Diesel Tuner requires
the engine coolant temperature (ECT)
to be above 110º before it will add
fuel. If the optional Banks PowerPDA
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, and/or 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 between automatic
transmissions, year model of vehicle,
and altitude.
Note: Before key-off, check tuner
for error codes. Use your Banks
PowerPDA or eGt 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. to avoid heat damage
to various engine components it is
recommended that the exhaust gases
cool below 400ºF before the engine
is shut down. Your six-Gun Diesel
tuner is calibrated to maintain eGts
depending on power level.
Level
EGT
1-5
1350°F
6
1400°F
You may experience brief excursions
slightly above the temperatures listed
under acceleration. this is normal and
the eGt should return to or below
the proper temperature 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.
