    Does the 74HC373 SMD Chip go with the numbers facing like the top picture, or the bottom one? It doesn't say on the Hondata installation instructions...

    It's going in a JDM P30

    Help?

    He told me on IM that his chip doesn't have a notch or a key mark anywhere...

    all of my 74HC373 chips had a notch in them...
    although he is using a surface mount chip which may be a bit different.

    Pin 1 is located by a dimple/dot/half moon

    On the JDM ecu's you'll see something like this screened on the board.


    _____
    /........| <--- the / is PIN 1
    |........|
    |........|
    |........|
    |........|
    |____.|
    sorry, my ascii skills are not up to par.....


    At any rate, find the dimple/dot/half moon and the / on the board.

    Then you have found Pin1
