Ok I have tried at least 4 cars. Every time I Turn on the Flex fuel Switch I get stuck in a Cold Start Emission Reduction Spark table that has no Timing in it. I know others are having this same problem. So is there something I am missing?
Edit just to clarify that on these cars the flex fuel logic is working and the cars start and adapt fine. It isn't until you drive them that you notice they have no spark advance.
