ok so tonight im going to start the process of tuning the VE file of my truck. i do not have a wide band sensor so thats gonna make things a bit more difficult. what i am curious to know is what feilds am i to view when doing my drive to get my LTFT as close to zero as possible also is it ok to drive the truck longer than 15 or 20 mins or do i need to just drive it 15-20 mins then smooth over the table and paste it as my ltft and repeat a like 5 times. thanks all P.s. i am using efi live
