    Default reflash issues

    ive only had this problem with LB7's so far. sometimes when i just flash the calibration onto the ecm the changes ive made take no affect on the ecm when this happens i perform a complete reflash of OS and cal and the changes take affect. why is this? what does this have to do with reflashing the OS?

    If it's a DSP5 OS then you need to full flash for the changes to take effect.
    I no longer monitor the forum, please either post your question or create a support ticket.

    im aware that i have to full reflash the first time to apply the new DSP5 OS, but are you saying i have to full reflash every time i make a change to the calibration?

    Yes, this applies to the DSP5 only though.
