I just ran across the fact that the e67 ECM can run a flex fuel sensor and calculate fueling and timing based on that sensor's input. I would love to use that feature in my 2007 Sky with the LE5 but I'm not seeing much info on this specific application. I know I have to get the sensor and wire it into the ECU harness and I've seen the screen shots of some of the settings that need to be changed in HPT but I have yet to see anyone successfully do this on the Ecotec.
Now I know that different platforms have different OSs and that the OSs are not compatible across platforms. Is there an OS for the ecotec platforms that lets you use this OEM flex fuel feature?
