Does anyone know how to pull volumetric efficiency values out of a AEM Series 1 ECM?

Short story long, I pulled the motor I am using out of car that was tuned on an AEM series 1 ECM. I will use ECMlink to tune and run the engine as its more straightforward to me than the old AEM and has all the functionality I need. I will run the engine using speed density. It was run with a speed density setup by the previous owner on the AEM ECM. I pulled a bunch of data off the AEM ECM thinking I was going to find a VE graph, chart, look up table, etc. but I couldn't find anything having to deal with VE. Am I missing it or do I need to do some back calculating to back it out of the fuel table, ECM parameters, etc.?

Thanks.
 
Those old AEM's didn't really use a VE map. They just had a fuel map, basically afr and ve rolled into one. You were inputting pulse width essentially.

Thanks, yeah that is what I saw in the fuel map and what I have been seeing from my research. So without a bunch of logs/other data parameters I can't back calculate anything.
 
The fuel table will be the VE table if the tune was using the "Boost Compensation Table" with the table input linear & with a speed density setup. It's not that there is or isn't a VE table. When tuned with Boost Comp & set linear the fuel table ends up being the VE representation.
