Hey all, this is a dumb question this far in the game, but I still don't know what every one of the acronyms in the EBL's dump file mean. I could be missing some stuff to help me tune hear becuase I don't know what I am looking at. Maybe we can make a chart and sticky it in the beginning of the EBL post? Or just have a nice .doc use less experianced users can D/L and save for reference? Thanks again.

Here are the current columns available in the .EBL dump file. Older versions of the WUD will be missing some of these columns (namely VAC & BRO, maybe Fpsi). Updates for the BIN & WUD are available to EBL owners ( at least for the life of the product).
Code:
RUNTIME Hours:minutes:Seconds of engine run time. This is from the ECM
RPM Engine speed
MPH Vehicle speed
MAP Manifold Absolute Pressure in KiloPascals (KPa)
BRO Barometric pressure in KiloPascals (KPa)
VAC Manifold vacuum in KiloPascals (KPa) (this is barometric minus MAP)
VE% Volumetric Efficiency, from BIN calibration
TPS Throttle Position Sensor in % (0 - 100%)
CTS Coolant Temperature Sensor in degrees F or C. Selected in preferences
IAT Intake Air Temperature in degrees F or C. Selected in preferences
I/C Blended value of IAT and CTS, used for fueling calculation
O2 Oxygen sensor value in milli-volts (450 mV is basically stoich)
G/S Grams per Second of airflow. Calculated by the ECM
SA Spark Advance in degrees BTDC
KnkCt Knock Count
sPW Synchronous injector Pulse Width in mill-seconds
aPW Asynchronous injector pPulse Width in milli-seconds
DC% Injector Duty Cycle in percent. Sync or async, which ever is active
Flags: shows a 'Y' when active, 'N' when inactive
AyAeDeIdPeDcClLnFnTcCpEg
Ay Asynchronous injection active
Ae Acceleration Enrichment active
De Deceleration Enleanment active
Id In idle mode
Pe Power Enrichment (WOT) mode active
Dc Decel Fuel Cutoff (DFCO) mode active
Cl Closed loop mode active
Ln BLM learn mode active
Fn Fan on active
Tc Torque convertor clutch (TCC) engaged
Cp Charcoal Cannister Purge (CCP) active
Eg Exhaust gas recirculation (EGR) active
Cl Cell, which BLM cell is in use (0-2)
INT Integrator, 128 is neutral
BLM Block Learn Multiplier, 128 is neutral
BPC Base Pulse Constant, ratio of injector flow to engine displacement
IAC Idle Air Controller in steps (0 is closed)
Fpsi Fuel pressure in psi. For Autometer 0-100 psi fuel pressure transducer
AFR Desired Air Fuel Ratio. ECM internal value
WB Wide Band AFR as reported from external device
dTPS Delta TPS % for Acceleration Enrichment (AE)
tpsAE AE pulse width from delta TPS%
dMAP Delta MAP value for Acceleration Enrichment (AE)
mapAE AE pulse width from delta MAP
aePW Final AE Pulse Width (compensated for CTS & RPM)
Awesome! Thanks Bob. I have a question, what is the BLM cells?? 0, 1, 2 ?? How do you edit them? I'll have to search around and see if I can learn what that is. That is new to me.

Reason: duh!
Ok, thanx Bob. I appreciate it. I am gonna keep this in my EBL folder for future use. Eventually I'll remember what they all are off the top of my head. haha
Could you possibly elaborate on this? When I'm idling the Cl will bounce between 0 and 2.
Probably the RPM threshold for idle vs deceleration. Check this one:
BLM - Idle Cell RPM Threshold
Basically, if the throttle is closed it will use cell 0 or 2. When the RPM is above the Idle Cell Threshold it uses cell 2 (decel). Otherwise it will use cell 0 (idle).
If the throttle is open cell 1 (cruise) will be used.
