Checking Engine Performance
1.
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.
2.
Start the engine and gently drive
the vehicle to 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 allow it to
cool. 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.
3.
The EconoMind Diesel Tuner
requires the engine coolant
temperature (EcT) to be above
110º before it will add fuel. If the
DynaFact gauges or the optional Banks
PowerPDA 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
occurring 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, fuel injection pump, and/or
dirty air filter.
Typical maximum boost pressure
settings for the cummins diesel will
vary considerably with year model of
vehicle, options, and altitude.
Note: Before key-off, check Tuner for
error codes.
4.
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. Your EconoMind
is calibrated to maintain a maximum
EGT of 1300°F. The EGT may exceed
1300° for short periods of time during
high-load conditions. 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,
a malfunctioning wastegate, fuel
injection pump, and/or dirty air filter.
CAUTION: To avoid heat damage
to various engine components it
is recommended that the exhaust
gases cool below 400º before the
engine is shut down.
