Data Parameters Engine Parameters
MAX. INDICATED ENGINE TORQUE
MIN. INDICATED ENGINE TORQUE
Range: __________________________________________________________ variable
Used on HFM systems. These parameters display the ECU-calculated minimum and maximum
engine torque in Newton meters (Nm).
MISF.RECOGN. SH-OFF THRESHLD
Range: __________________________________________________________ variable
Used on ME10 and ME20 systems. This parameter is the specified threshold that a misfire must
surpass before it is considered a misfire. Crankshaft acceleration is measured for each cylinder-
firing event. If acceleration drops below a specified threshold, a misfire occurred.
MISFIRE CYLINDER 1 to 8
MISFIRE CYLINDER 1 to 12
Range: ______________________________________________________ not available
Used on ME10 and ME20 systems. The “1 to 8" and “1 to 12" in the parameter names represent
twelve separate parameters, one for each cylinder. These parameters are only active if a misfire
occurs. The display represents the actual RPM drop for each individual cylinder, which must drop
below the shutoff threshold before it registers.
MISFIRE FAULT COUNTER CYLINDER 1 to 12
MISFIRE COUNTER CYLINDER 1 to 4
Range: __________________________________________________________ variable
Used on ME10, ME20, ME27, ME28 and SIM4 systems. The “1 to 4" and “1 to 12" in the
parameter names represents up to twelve separate parameters, one for each cylinder. These
parameters represent the number of times a particular cylinder has registered a misfire. To
register a misfire, the RPM of the cylinder must fall below the shutoff threshold.
MIXTURE ADAPTATION
Range: __________________________________________ INHIBITED/NOT INHIBITED
Used on ME27 and ME28 systems. This parameter states whether the short-term ECU is
permitting fuel metering correction to maintain a stoichiometric (14.7:1), or 1.0 Lambda, air-fuel
ratio. NOT INHIBITED indicates a 1.0 Lambda air-fuel ratio. INHIBITED indicates an air-fuel ratio
other than 1.0 Lambda.
MULTIPLE COMBUST MISF. TWC PROT.
MULTIPLE COMBUST MISF. EMISS. LIM.
MULTIPLE COMBUST MISF. I/M PROGR.
MULTIPLE IGN. MISF. TWC PROTECT.
MULTIPLE IGN. MISFIRE I/M PROGR.
MULTIPLE IGN. MISFIRE EMISS. LIM.
Range: __________________________________________________________ YES/NO
Used on DM2 systems. These parameters indicate whether the onboard tests for misfire
monitoring programs have run or are running.
MULTIPLE MAP ADJUSTMENT ACTIVE
Range: __________________________________________________________ ON/OFF
Used on HFM systems. This parameter indicates whether multiple MAP adjustment system is on
of off. No further information is available at this time.
NOMINAL AIR MASS
Range: ______________________________________________________0 to 255 mg/S
Used on EDS and ERE/EVE/ASF (IFI Diesel)). This parameter reports the desired air mass
reading for a normal running engine in milligrams per second (mg/S). Most port fuel injection
