So for years iv been using HPT for gas tuning and recently with everything im doing in efi for diesel stuff I have a turbo ls truck i want to learn to tune gas vehicles with in EFI. The thing that has me the most confused is logged data in maps, Im used to just copying the data say stft % from the ve table histogram, and going to the tune and pasting and multiplying by %. I can not for the life of me figure out how to do this with efi scanner. Theres so many differences its hard to grasp. I read about ben factor, and then i see paste settings in the map where I figured when i selected multiply when i ctrl+v. But it gives me crazy numbers. hpt has many predefined maths but efi has none. Iv tried reading through tutorials and the help docs but nothing is really jumping out to me where i need to start. Any insite is appreciated
