There appears to be a fair bit of confusion over what the Syvecs PC applications are, what they do etc and since their names may seem a little cryptic below is a brief description of them :
SCal - Syvecs Calibration program, used to edit maps.
SCfg - Syvecs datalogging Configuration program, used to tell the ECU what to log internally
SData - Syvecs Datalog retrieval program, used to fetch datalogs from the ECU to the PC
SView - Syvecs datalog Viewer, used to graphically display datalogs
SMon - Syvecs Monitor, used to display ECU running parameters
SMsg - Syvecs Messages, used to show status messages from the ECU
In Syvecs terminology a Calibration is a collection of maps. This may refer to one of two things depending on the context. When referring to data it normally represents the entire collection of maps held in an ECU, typically when loading, saving or flashing a calibration. When referring to the current operating mode of the ECU it refers to a given combination of maps which are currently in use. To better understand this concept, consider that there are four fuel maps but only one of them can be in use at any one time; the Calibration Switch is used to choose combinations of maps (fuel, ignition, boost, lambda, ALS etc) so we may say that we're in Calibration 1 (CAL1) for example (but that could well use Base Fuel Map 4).
