I always hear to read the calibration help file in Tunercat, but its not possible for me to do. It is always grayed out when I have the EE ecm selected. The 42 ecm (that Tunercat comes with) allows me to read the calibration help file, but that doesn't tell me anything. No matter what I have open in the program, as long as I have the EE ecm selected, I can't use the calibration help file. Does anyone have any ideas? Or maybe someone could just send me their help file? Its probably called Ecm_EE and has a question mark on the icon. Thanks.
