ECM Help.
I need some help for a new project im working on.I have been getting conflicting info on several ecm diagrams from various GM makes on the computer.
The 2 im looking into are the 727 and the 730 ecm.What i want to know is:
1: Are the ECMs the same on the circuit board in the computer,and the various pinouts are tied to the eproms installed in them?
2:Or are the ecms different on the circuit board internally for what they are installed into.As far as the pinouts go?
Any clue would be welcomed.

Re: ECM Help.
AFAIK the boards are the same, the pinouts to the Memcal are the same, The pinouts to the connectors are different.
