I am setting up an E85 only tune, manually not flex fuel, on the 02020005 OS and I have done a few searches where all I need to change is B3601 to the stoich ratio of the blend used (using an Innovate gauge for content). If this works how do you go below 10 AFR which is the efi limit? I see that the controller limits have a much wider range so if I put in a value like 9.8 AFR and flash will it truly be 9.8 in the controller? When efi saves it goes back to 10. I am a bit confused so any help with this would be appreciated.
