    Default ECM interchangeability

    Each year group from 2011 has it's own E86 service number called out. I have LML/LGH ECM's and want to hear from those who have personal experience tuning ECM's for use in non-standard combinations. Success and failure.

    In my testing the ecms have no issues running the many different OS/Segments, I personally have cross tested the 2011 OS in the 12-13-14 and the 12 OS in a 11-13-14 and the 13-14 OS in an 11-12.

    All will flash and run a LML no matter what computer.

    I have 7 new ones here and I have tried pick-up specific CALS in LGH and the trucks will run, however the the fuel tank segments are unique to the LGH as are the engine operation calibration, etc.

    I can fix that- without segment swap. or retune for titan tank, etc..


    but yeah- all E86a will go on E86a.
