Question on installing Hondata

[civicious]

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?

the notch on the chip faces the plug side

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.

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
