Abstract

A method for performing application review validation testing for an engine as installed in an application, the engine having production sensors and a production electronic control unit (ECU) for controlling the engine using the production sensors, includes running the engine; reading an output of the production sensors with the production ECU during the running of the engine; and determining with the production ECU whether the engine as installed in the application is in compliance with at least one requirement of the application review validation testing based on the output.

15. The method of claim 1, further comprising said ECU transmitting test data based on said output to an off board device via one or more of a direct, wireless, and internet connection.

16. The method of claim 1, further comprising said production ECU determining whether to auto-initiate said application review validation testing.

17. The method of claim 16, wherein said application review validation testing is auto-initiated based on one of:

an amount of time since said engine has been installed in said application; and

an amount of engine operation since said engine has been installed in said application.

18. The method of claim 18, wherein said application review validation testing is auto-initiated based on one of:
