I have a PCM (powertrain Control Module a.k.a. ECM)
from a 1999 GMC sierra pickup truck. The connectors
are almost bigger than the circuitboard itself.
Well, anyway.. i have it open, and here's the info
from the flash ROM chip:
Intel
16236995
AB28F400BX
E 5012
U7400142Q
Flash
44 pins
It's a surface mount device, but i plan to solder
little wires to it and to a connector so i can
plug it into my ROM burner (while it's in vivo).
Does anyone have any suggestions or information
as to whether this could be a bad idea or has
anyone done it? I asked GM for a PCM programmer
kit but surprisingly, they refused to give me one.
Thanks!
