    Default DSP2/5 Question

    Those of us in snow states sometimes have different wheels & tires for the summer & winter. Most of the time they are different heights. Do you think we could get the ability to adjust the speedo calibration for the DSP tunes so there is no need to load a tune from a laptop when we change tires for the season?

    No, the speedo stuff is only checked once by the ECM at start up, so switching the tune would do nothing whilst running. But I suppose I must ask the question given it takes 30 seconds to reflash the truck what is wrong with doing that at the change of seasons?
    Need official EFILive help, please go here.
    For tuning support please post your questions on this forum (or other auto forums).
    Sorry if I don't respond to your PM, don't take it personal.

    Thats what I have been doing but I have customers that aren't that savvy with computers & this would have been a lot easier for them. Thanks for the quick response.

    Tell em to wait another few months til AutoCals are running around, then you can load their stock tune, DSP tire size 1, and DSP tire size 2 tunes to it. All they have to do is press the button and do the key off stuff.
