    Default Looking for a 3.5L or 3.9L Flex Fuel tune

    Anyone have a 3.5 or 3.9L flex fuel engine cal file?

    I checked Holden Crazy and nothing there.

    Thanks!

    What engine is that?

    At least in E38, the only cals on Holden Crazy for Flex Fuel are probably 5.3L truck, and maybe some LS1 PCM's.

    The 3.5 and 3.9 are the primary engines in the GM lineup of wrong wheel drive cars like the Impala.

    The 3.5L I know is FlexFlex, the 3.9L not sure. But I am looking specifically for a FlexFlex V6 calibration to look at.

    I am just looking at the data in the file, not putting it into anything.

    So really anything you have is good.
