    Hi All,
    Just got me an old snap on mt2500.
    Seems to be a handy tool for the year cars I have. I would like to use the display section but don’t know how yet.
    My question is how to get the original fuel trim charts for my 99 grand cherokee.
    This is so I can compare future readings to original.
    thanks,
    Paul

    There are know real fuel trim charts. What we like to see is 10% positive to 10% negative. The readings may spike to 25% either
    direction. But the more the 20-25% range is held there you will set a code.
