  • ECU upgrade steps and flash

    Do I have the ecu upgrade steps correct to use newer ecu tune?

    -Upgrade ecu to next version (0CM21 -> 0CM22)
    -Copy/paste custom tune settings from 0CM21 file to 0CM22 tune file
    -Flash customized 0CM22 to truck

    Just want to make sure i got steps right before i push buttons.

    I cant flash an 0CM22 file directly on my ecu without first upgrading it right?

      I'm not certain of the update process within vF because I believe it's not finalized for us Tacoma owners yet.

      Regarding flashing a tune with a different (updated) ID, yes, you need to update your ECU before you can flash the tune.
