Banks Six-Gun® Diesel Tuner - Bankspower - Banks Power

Section 6Checking Engine PerformanceThe Six-Gun Diesel Tuner requires theengine coolant temperature (ECT) tobe above 110º before it will add fuel.If the optional Banks IQ or DynaFact ®gauges are installed, observe theoperation of the boost and pyrometer(EGT) gauge values while driving undervarying conditions. Turbochargerboost pressure will increase as afunction of load and engine RPM,thus the engine will produce littleboost while cruising at light throttle,with maximum boost while climbinghills, heavily loaded, and/or duringacceleration. Note the boost level seenduring hard acceleration with a givenload. If performance seems to havedeteriorated sometime in the future,the maximum boost figures may becompared to see if boost has droppedoff. Lower boost may be caused byturbo ducting leaks, a malfunctioningwastegate or fuel injection pump,or dirty air filter. Typical maximumboost pressure settings will varyconsiderably between automatictransmissions, year model of vehicle,and altitude.Note: Before key-off, check Tunerfor error codes. Use your Banks IQor EGT gauge to monitor exhaust gastemperature (EGT) in the engine. Atidle, exhaust gas temperature willbe very low, perhaps only 300°F. Asthe engine is accelerated for higherspeeds with greater loads, the EGTwill rise. The highest EGT will be seenunder maximum load at full throttle,such as climbing a steep grade witha heavily laden vehicle. To avoid heatdamage to various engine componentsit is recommended that the exhaustgases cool below 400ºF before theengine is shut down. Your Six-GunDiesel Tuner is calibrated to maintainEGTs depending on power level.LevelEGT1-5 1350°F6 1400°FYou may experience brief excursionsslightly above the temperatures listedunder acceleration. This is normal andthe EGT should return to or belowthe proper temperature within a fewseconds. If you find that EGT remainshigh for any length of time, check forboost leaks or a dirty air filter.-END, SECTION 6-96819 v.3.0 21
