8.3 Data log fields 8 TROUBLESHOOTING AND DATA LOGGING
• GPS Lat. deg: Latitude degrees component from external GPS.
• GPS Lat. min: Latitude minutes component from external GPS.
• GPS Lat. sec: Latitude seconds component from external GPS.
• GPS Longitude: Longitude degrees from external GPS. (Combination of degrees, minutes, seconds as one
decimal number.)
• GPS Lon. deg: Longitude degrees component from external GPS.
• GPS Lon. min: Longitude minutes component from external GPS.
• GPS Lon. sec: Longitude seconds component from external GPS.
• GPS Lon. E/W: Longitude East/West indicator from external GPS.
• GPS Speed: The speed from external GPS in your chosen speed units.
• GPS Speed ms-1:The speed from external GPS in meters per second.
• Ign Load: The load variable used on the Y-axis of the ignition tables.
• Injector Timing pri: The injection timing used for primary injector channels.
• Injector Timing sec: The injection timing for secondary injector channels.
• Knock cyl# 1-12: The signal value per-cylinder from the internal knock sensor interface.
• Knock In: The signal value from an optional add-on knock sensor interface.
• l/100km: Fuel economy in litres per 100 kilometres.
• Lambda (1-8): Lambda reading from wideband EGO sensors 1-8.
• Lambda 1 Target: The current target value for Lambda (1,2), looked up from the active target table.
• Lambda 1 Error: The difference between actual and target Lambda.
• Launch retard timer: The time after launch control has been released, if using timed retard or timed boost
after launch.
• Launch timed retard: The retardation to the timing due to the timed-retard after launch.
• Load: The primary load variable for fuel calculations. This is equal to MAP on typical speed-density installa-
tions.
• Long term fuel trim cor: Fuel correction due to long term trim.
• Loop: This bitfield is used with the Programmable on/off outputs feature and allows other features to be
controlled by user-defined combinations. The number will tell y ou which of the three Loop settings has been
triggered.

• Lost sync counter: The count of "lost-sync" events. If the engine stalls the counter will increase by one.
During startup it is acceptable to have a few lost syncs. If you see this counting up under other conditions
while the engine is running, there is a problem with your tach input.
• Lost sync reason: A technical reason code for why the ECU lost synchronization with the tach input. See
section 8.4.1 for an explanation of the numbers.
• MAF: The air-flow in g/sec calculated from the MAF sensor.
