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.
