    Default reset fuel trims

    how do i reset the fuel trims using only the blue hand held??

    i have gone through every option on the handheld and cannot find "reset fuel trims"

    also when i read any pcm the handheld says missing config file

    it will log and display pids just fine though....

    V2 resets the trims when you flash the ECM.
