During open loop tuning isn't there some things that need to be disabled or set to get a good accurate open loop tune? I already have the closed loop enables set to an impossible temp to reach, but I think I heard other things need to be set or disabled. Like the modifiers. Can anyone help me out on what all I need to set or disable to get a good accurate open loop tune with tunercat on my OBD1 LT1? Thanks.
