5.6 ENGINE MONITORING
SPEED
 Engine Speed (203) – actual engine speed in rpm, calculated over a minimum crankshaft angle of
720 degrees divided by the number of cylinders
FUEL
 Fuel Level (198) – independent of source (only analog input supported currently)
 Fuel Level (258) – for legacy support only; for new applications, use (198)
 Fuel Level from I/O Pin (804) – read from analog input (recommend using 198 instead)
 External Tank Fuel Level from I/O Pin (805) – read from analog input
 Engine Fuel Temperature from Data Link (246)
 Fuel Pressure from Data Link (247)
 Total Fuel Consumption from Data Link (254)
OIL
 Engine Oil Temperature (199) – independent of source; i/o pin (if configured) takes precedence
over datalink
 Engine Oil Temperature from Data Link (245)
 Engine Oil Temperature from I/O Pin (800) – for legacy purposes only; for new applications, use (199)
 Engine Oil Pressure (200)
 Engine Oil Pressure from Data Link (217) – for legacy support only; for new applications, use (200)
 Engine Oil Level from I/O Pin (806) – for legacy purposes only; this will always read zero; for new
applications, use Custom Parameters instead
 Engine Oil Priming State (423) – read from CAN data link
COOLANT
 Engine Coolant Temperature (201)
 Engine Coolant Temperature from Data Link (219) – for legacy support only; for new applications,
use (201)
 Engine Coolant Level from I/O Pin (807) – for legacy purposes only; this will always read zero; for
new applications, use Custom Parameters instead
