fuel trims

hi when you add both the correction and learning trims known as total trims do you set that up before the log or after the log has been made?

secondly after logs on romraider you save that file and open it on megalog how is it done?

If you're using MLVHD for your analysis then the total trim is simply a user math channel you can set up any time. If you add a new math channel MLVHD will prompt you that it needs to reload the log file to take advantage of the channel but it does this automatically.

The RR log files are just saved as a .csv format anyway which MLVHD can natively read so it's just a case of finding the folder that RR saves the log files to and opening them from there in MLHVD.
