| | Method and system for recalibration of an electronic control module - US Patent 6571191 (Site not responding. Last check: 2007-09-14) |
 | | ECM 17 also includes a memory 18 that can store data accumulated from various engine sensors, as well as programs and associated data for controlling the function, and therefore the calibration, of the engine. |
 | | In a further refinement of the present invention, the recalibration of the ECM includes security authentication/verification checks to ensure that the electronic control system, such as ECM 17, is not subject to unauthorized recalibration. |
 | | It is contemplated that the calibration upgrade table will identify the particular electronic controller, the date of the calibration, the nature of the re-calibration, and the data necessary to perform the re-calibration. |
