Re: diagram for location of ECM (Engine Control Module) not specifically identified

Hi,
I checked your solution at the AutoZone site. Closest I come to the ECM is
the ICM (Ignition Control Module) at following link:

I'm not sure that the ICM is actually the ECM. The ECM (Engine Control Module), I believe, controls much more than the ignition timing but also fuel mixture at various RPMs and loads. I just can't seem to locate any schematics or specific information on the AutoZone site that describes the ECM. I need a diagram specific for the ECM since I am researching a reprogramming of the ECM by a company out of MT (PowerUpDiesel) that will set up my vehicle's ECM computer to provide the most efficient metering of fuel for increased power and fuel efficiency, specific to my vehicle (i.e., I provide my ECM with VIN # and tire size and they reprogram the module more accurately than the manufacturer's stock program).

I may need to just go down to my local Chevrolet dealer and get the information but thought that I could save myself a trip by getting advice from others here
