Seems like main issue with Flex Fuel will be how to get the signal from the content analyzer into the ECU. I saw where Ecutek can now do this via the rear O2 sensor instead of the EVAP Purge Solenoid. Obviously you still need your rear O2 to be in full compliance but hopefully they are working on something that can still use the factory ECU and we don't have to switch to a stand alone ECU!

Eugene does it through o2 feedback as does some GM vehicles. When at GM though I had vehicles that wouldn’t re learn because drivers would not drive the vehicle to meet the requirements to re learn (essentially would not do a long enough drive after switching back) and then the vehicle would get stuck and run rich until you forced a reset in the ecu. So I went with Sebs tune with a sensor but maybe ecutek can do a better job with just o2 than GM algorithm.
