Thanks to all of those great responses 'bout
opening the ECU. I read it last month or so but
couldn't find it when needed. Once you've done it,
you just can't forget that procedure. Incredible
to get responses in less than 10 minutes!

Here's what I got:

Stickers on main board (looks socketed) LS4-P294
and a yellow dot L1 on the square chip to the
left.

Left hand board LS4-EZ91 and a L7 on the yellow
dot on the square chip closer to the bottom.

Bosch 0 273 003 210  250 kPa 078 pressure
transducer.

PO had said MTM1, car was from MD.  Any ideas?
