    Flex fuel idle gets richer as temp increases

    I guess that I have one or more flex tables wrong. On 93 octane, my stft's stayed steady but since I installed the GM flex sensor, at idle as the engine temp increases, it runs richer? Can you tell which table (or multiple) that I have wrong? Thanks

    I had changed IVT Terms to a newer Camaro setup. I changed it back to my original setting of 3.96---all is good.

    Can you give me a link or part number for the GM flex sensor that you installed?
