GM C4 info anyone?

[Chief]

I have a GM C4 ECM on my Monte SS.   Does anybody know a good source of
information on how these things work, whether be it a web page or book.  I
have a service manual but it doesn't explain a lot about advance curves,
fuel curves, processing variables, etc.

I know this is kind of off the FI subject, but it does have a TPS, O2
sensor, VAC sensor, coolant temp sensor, just a feedback carb with mixture
control instead of injectors.  Almost there, huh?

Please e-mail me directly.  Thanks.
