ECMs (Engine Control Modules) and PCMs (Powertrain Control Modules) are employed in the engine's computer module. Although a PCM is a single unit from the outside, it often has a separate ECM and TCM, each with its CPU and programming ROM. During most activities, they operate independently, exchanging data only when a function needs both systems to work together. For tuners, this implies that programming on one system may be altered while keeping the other unaffected. The PCM may monitor the car's performance using sensors such as temperature, oil and fluid level, air intake, emission level, camshaft angle, or ... Read More
