Abstract: Disclosed are methods, systems, and non-transitory computer readable memory for updating vehicle modules. For instance, a system may include: a user interface device configured to: receive and store a re-program file; and display a graphical user interface configured to receive a user input to initiate a re-program process for at least one onboard module of a vehicle. The system may also include a programming device configured to be physically and communicably coupled to an onboard port of the vehicle. The programming device may be configured to: receive, via a defined sequence of messages with the user interface device, and store, via defined operations with a local cache, mapping-and-byte data; re-program the at least one onboard module using the mapping-and-byte data; and in response to determining a checksum condition is satisfied, transmit a re-program success message to the user interface device.

Abstract: Disclosed are methods, systems, and non-transitory computer readable memory for staging data and updating vehicle modules using staged data. For instance, a system may include: a user interface device configured to: receive and store a re-program file; and display a graphical user interface configured to receive a user input to initiate a re-program process for at least one onboard module of a vehicle. The system may also include a programming device configured to be physically and communicably coupled to an onboard port of the vehicle. The programming device may be configured to: receive, via a defined sequence of messages with the user interface device, and store, via defined operations with a local cache, mapping-and-byte data; re-program the at least one onboard module using the mapping-and-byte data; and in response to determining a checksum condition is satisfied, transmit a re-program success message to the user interface device.

Abstract: A performance system can enable an untrained end user to analyze the performance of a vehicle based on performance data that the vehicle's ECU generates. The performance system can include a performance tool that is configured to request performance data from one or more ECUs of a vehicle. The performance system can also include a performance engine that interfaces with the performance tool to create a log of the performance data. The performance engine can be configured to process the performance data log to generate a number of performance values which correspond to performance parameters. The performance engine can then use the performance values to generate performance representations which can then be presented to the end user.
