1. A system to allow an aftermarket electronic control module to alter or control an automotive vehicle response by special controller area network messages only, the system comprising:
a) at least one microprocessor based memory; and b) at least one processor configured by the memory to perform the steps of:
(i) receiving a first electronic control broadcast message directed to at least one receiving module; and(ii) causing a subsequent electronic control broadcast message to alter a specific data characteristic of the first electronic control broadcast message to spoof or mimic a condition that will cause the at least one receiving module to function differently than it would have under the first electronic control broadcast message.
