I have a P06 ECU made into a P28 and its zif socketed. Which way does the chip go in? There is a triangle marking and a U notch on one side of the chip.

 

the little u should face the connector

 

the U shaped notch on top of the chip goes towards the CN2 holes or towards the 74HC373 footprint. Click the link and scroll down a few pics and you'll see which way the U shaped notch faces on the installed chip.

The U-notch faces the same way every other chip on the board with a U-notch faces.
