Devices, systems and methods for replacing a factory installed or similar air suspension controller in a vehicle with an augmentor, which sends correct status messages to the vehicle main computer when the air suspension is replaced with coil springs or shocks. The augmentor can includes a voltage regulator, an indicator and bus interface. At power on, the program initializes the microcontroller registers, timer registers, and control registers, then loop until an inquiry or command is received, then responds with status messages that are the same as the status messages sent by the original factory installed air suspension controller until power is removed.
