EBL Dump File header explination
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).

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.

The BLM cells are: 0 is idle, 1 is cruise, and 2 is decel (throttle closed and not in idle).
By edit, you can change the thresholds that the ECM uses to decide which cell to use. The cell value itself is the long trim fuel trim.

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

Re: EBL Dump File header explination
Could you possibly elaborate on this? When I'm idling the Cl will bounce between 0 and 2.

Re: EBL Dump File header explination
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.

Re: EBL Dump File header explination
so revisiting this thread, the EBL SFI-6 has addition headers, like F1, F2, etc. Could you shine some light on all the additional headers?
Also, is there a way to tell from a log when the second pump is running?
Thank you!
