C3 & P4 ECM information

[Eric Elliott]

Hello,
The older GM ECMs were well discussed in this mailing list about 3 years
back. The web site makes archive downloads easy. Just search the archive for
"C3" or "P4" or....
Some letters in the archives describe books that describe the ECMs.
Also mentioned are books that give values for the various sensors used with
domestic & foreign ECMs.
The recent letter about what resistor to make the water sensor lie about
temperature could have easily been answered by letters replied in the
archives.
