The system comprises a remote computer, a central server, a local computer and setup comprising at least a dynamo meter, and at least one actuator. The dynamo meter and the actuator are interfaced and operated with the local computer. The central server is connected to the local computer by a second networking means, and a remote computer is connected to the central server by a first networking means. The remote computer, uploads instructions to the central server, executes the instructions through the local computer to operate the dynamo meter and the actuator, and calibrates the ECU of the vehicle. The instructions are downloaded to the local computer by the second networking means. ## Claims ### Claim 1 A system for calibrating an Engine Control Unit (ECU) of a vehicle, the system comprising: at least a dynamometer; at least one actuator; a local computer interfaced with and configured to operate the at least one dynamometer and the at least one actuator; and a remote computer connected to the local computer through a central server by a first networking device and a second networking device, the remote computer being configured to: upload instructions to the central server; execute the instructions through the local computer to operate the dynamometer and the at least one actuator; and calibrate the ECU. ### Claim 2 (depends on 1) The system as claimed in claim 1, wherein the remote computer is further configured to: display a result uploaded to the central server, the result being uploaded to the central server by the local computer after an end of the calibration. ### Claim 3 (depends on 1) The system as claimed in claim 1, wherein said the at least one actuator includes at least one of a throttle actuator, a brake actuator, a gear actuator, a clutch actuator, and a fuel injection module. ### Claim 4 (depends on 1) The system as claimed in claim 1, wherein the remote computer is further configured to: selectively upload and execute instructions corresponding to the at least one actuator based on a selection by a client. ### Claim 5 A method for calibrating an Engine Control Unit (ECU) of a vehicle, the vehicle being operated by a dynamometer and at least one actuator through a local computer, the method comprising: connecting a remote computer to the local computer through a central server; uploading instructions to the central server with the remote computer; and executing the instructions with the local computer to calibrate for said ECU. ### Claim 6 (depends on 5) The method as claimed in claim 5 further comprising: uploading a result of the calibration to the central server with the local computer; and displaying the result with the remote computer. ### Claim 7 (depends on 5) The method as claimed in claim 5, wherein the method is performed in at least one of an automatic process and a guided process through a user intervention. ### Claim 8 A device for calibrating an Engine Control Unit (ECU) of a vehicle, said the vehicle being positioned on at least one roller of a dynamometer and being operated with at least one actuator, the dynamometer and the at least one actuator being interfaced with the device, device being configured to: connect to a central server through a second networking device; download at least one instruction from the central server; execute the at least one instruction to operate the dynamometer and the at least one actuator, and calibrate the ECU. ### Claim 9 (depends on 8) The device as claimed in claim 8, wherein the device is further configured to: upload results of the calibration to the central server for analysis. ### Claim 10 (depends on 8) The device as claimed in claim 8, wherein the device is a local computer.
