Banks Power Chevy_GMC Trucks: Duramax LLY-LBZ (Diesel ’06 - 07 6.6L) Tuner- Six-Gun Diesel Tuner '06-07 (iQ) Compatible with Optional Banks iQ & Speed-Loader - Manual (Page 22)

96817 v.3.0
The Six-Gun 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 iQ 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 400º before the
engine is shut down. Your Six-Gun
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.

CHECkING ENGINE PERFORMANCE
The Allison 1000 6-speed automatic
transmission will continually adapt
to the power output of the engine to
optimize shift quality. The transmission
will quickly adapt to the power setting
if the driving cycle includes regular
gear changes at high loads. The
transmission learning procedure will
need to be repeated when switching
back to the higher power settings
once the transmission adapts to
the lower power settings. It will be
apparent when the transmission
adapts to the lower settings by
monitoring the feel of the gearshift.
Gear changes will be noticeably harder
when initially switching from a higher
to lower power setting. This will soften
as the transmission adapts to the new
setting.
