TIME

ELECT. ENG. CONTROL CHAPTER : 3500B CONFIGURATION PARAMETERS

LOW IDLE :

Minimum RPM at which the engine can operate. MIN 810rpm

COOLDOWN SPEED :

RPM at which the engine will run during the cooldown period.

MIN 810rpm

COOLDOWN TIME :

MAX 990rpm

MAX 1800rpm

The amount of time the engine will run at the cooldown speed . Programming this parameter to 0 will disable this function. MIN 0mn

MAX 30mn

* If there is an EMCPII to this engine , this parameter could be programmed to 0 as the EMCPII performs this function as well.

PRELUBE TIME :

Time the engine control will prelube the engine. Programmed to 0 will disable this function. MIN 0s

CYCLE CRANK TIME:

The time the starting motor will be energized & the amount of cool down time both time being EQUAL. MIN 0s

MAX 60

* 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

CRANK TERMINATE SPEED : Engine RPM at which the starting motor is disengaged. MIN 100rpm

MAX 1000rpm

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 . Enable

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

ELECT. ENG. CONTROL CHAPTER : 3500B COLD START LOGIC

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.
