CONFIGURATION PARAMETERS
24 Page:
ACCELERATION DELAY :
During startup the engine will stay at low idle until oil pressure is above 70 kPa or until the "time-0ut" of the programmed Acceleration Delay .
Programming to 0 will disable this function MIN 0 s MAX 10 s
ACCELERATION RAMP RATE :
This parameter defines the acceleration ramp rate from Actual speed to Desired speed.
MIN 1RPM/s MAX 200RPM/s

25 Page:
COOLDOWN TIME :
The amount of time the engine will run at the cooldown speed . Programming this parameter to 0 will disable this function.
* If there is an EMCPII to this engine , this parameter could be programmed to 0 as the EMCPII performs this function as well.
MIN 0mn MAX 30mn LOW IDLE :
Minimum RPM at which the engine can operate. MIN 810rpm MAX 990rpm
COOLDOWN SPEED :
RPM at which the engine will run during the cooldown period.
MIN 810rpm MAX 1800rpm
MIN 0s MAX 210s PRELUBE TIME :
Time the engine control will prelube the engine. Programmed to 0 will disable this function.
CONFIGURATION PARAMETERS
26 Page:
MIN 0s MAX 60 CYCLE CRANK TIME:
The time the starting motor will be energized
& the amount of cool down time both time being EQUAL.
* If there is an EMCPII to this engine , this parameter could be programmed to 0 as the EMCPII performs this function as well.
TOTAL NUMBER OF CRANK CYLES :
The number of crank cycles that will be preformed. MIN 0 MAX 10
MIN 100rpm MAX 1000rpm CRANK TERMINATE SPEED :
Engine RPM at which the starting motor is disengaged.
AIR SHUTOFF and ETHER CONTROL :
If there is no air shutoff install on the engine then it should be programmed to OFF , that will prevent diagnostic from being logged on the air Shutoff driver in the ECM .
E-TRIM FEATURE
27 Page:
ALL ENGINES BUILD STARTING MAY 15, 1996 HAVE THE E-TRIM FEATURE ON THEIR PERSONALITY MODULE AND INJECTORS CODED WITH AN E-TRIM CODE
THE SOFTWARE COMPENSATES FOR INJECTOR VARIATION IN TIMING AND DISCHARGE. THE E-TRIM IS A 4 DIDGIT CODE ETCHED ON THE INJECTOR TAPPET
WHEN AN INJECTOR IS CHANGED THE NEW INJECTOR'S E-TRIM CODE MUST BE
PROGRAMMED . IF THE NEW CODE IS NOT PROGRAMMED THEN THE PREVIOUS CODE IS ASSUMED
IF AN OLD INJECTOR ( NO E-TRIM CODE ) IS INSTALLED , THEN ENTER THE DEFAULT CODE 1100
IF IT IS NOT POSSIBLE TO REPROGRAM AN INJECTOR CODE IMMEDIATELY THE ENGINE WILL NOT BE SEVERELY HARMED , ALTHOUGH IT SHOULD BE REPROGRAMMED AS SOON AS POSSIBLE TO OPTIMIZE ENGINE PERFORMANCE AND PREVENT ANY LONG TERM DETRIMENTAL EFFECTS

ECM automaticalty stop injection
to non- firing injectors until the
engine warm up based on water temp.
ECM cutout each cylinder for a
brief amount of time to see if that
injector is contributing to power.
If not, injection will be stop to that
cylinder, ECM will retest any cutout
cylinder every so often.
