    Lean cruise patch for OS 12212156 and OS 12587603

    Edit 05/05/22: Fixed a couple of errors.

    The other thread on lean cruise got me thinking about creating posting a couple of patches I made to activate lean cruise in OS 12212156 and OS 12587603. The latter also has a patch to activate flex fuel.

    When applying the Lean Cruise patch make sure to write a full flash and it should populate the table necessary to get you started tuning your combination. Make sure to use a wideband to verify your air/fuel ratio.

    If there are any errors please let me know and I'll do my best to correct them.
