It's not as simple as it seems. I also built an F20 bench. I came across the same problem - ELV. Of course, I added ELV to my bench. I tried different Virgin files for ELV a dozen times. Unfortunately, without a positive effect. I have contacted various colleagues from this forum regarding this matter. One of them told me that when Virgin ELV is installed in a complete car, there is never a problem, but the bench remains problematic. It seems that something else is missing for ELV to work. I even expanded my bench with a DME and DSC module, but that didn't help either. of course I found a way to get KL15. Just use INPA to turn on Montage Mode for FEM. Then you can control the terminals KL15 and KL30 on the bench. Of course, the car would not start in montage mode, but on the bench it works without any problems. I even flashed in this mode using Esys.
I would also like to know a way to get ELV to work on the bench.

Maybe using ELV emulator ?

I have never seen an ELV emulator for the F series on the market, only for the E series
