You're making headway, keep it up. If it's your first time working with EFI it's a steep learning curve, keep working at it!

Your log has very few PIDs, all of them except your long term fuel trim have data which is a step in the right direction. Can you post your most recent tune file? Your tune acts like an input, and a log acts like an output. Looking at your input and output helps determine what needs to change or stay the same with your input.

Your log is extremely short, it looks like you turned your car on, gave it some gas, and got a 46 second log. Good start, generally when you log you want to try getting a lot of data, 20+ minutes if possible. Since you're still getting the hang of things, these short logs to verify your PIDs are correct are good. Try adding some more PIDs and getting another log, where you see data for each PID after stopping and saving your log. PIDs that reference short term and long term fuel trims will help, also knock retard and E38.APCYL_DMA are helpful. Because you have an E38 ECM, you can choose "E38 ECM" from the drop down menu on the PIDs tab and filter PIDs that SHOULD work with your car. Note SHOULD because each computer's operating system is different.

For the calc_pids.txt file, I'll attach mine for reference. It has A LOT more PIDs than you need, but hopefully you can look at it as a reference and see how the nomenclature works and what it looks like to make your own PIDs. Only use it for reference, you don't want extra PIDs clogging things up and adding complexity where it isn't needed.
