 In order to datalog an aftermarket sensor in the ECMLink application,​ you must first tell the application where to find the sensor (which ECU input pin it's connected to).  You do that in the "Pin Assignments for Datalogging (PC-side)"​ section of the ECU Inputs tab shown to the right (click to enlarge). In order to datalog an aftermarket sensor in the ECMLink application,​ you must first tell the application where to find the sensor (which ECU input pin it's connected to).  You do that in the "Pin Assignments for Datalogging (PC-side)"​ section of the ECU Inputs tab shown to the right (click to enlarge).

 We have pre-defined a number of common sensor calibrations for you.  These include things like the Innovate LC-1 wideband, the GM 3 and 3.3-bar boost sensors, the AEM boost sensors, etc., etc.  A complete list can be found on our [[externalsensorlist|Supported Aftermarket Sensors]] page. We have pre-defined a number of common sensor calibrations for you.  These include things like the Innovate LC-1 wideband, the GM 3 and 3.3-bar boost sensors, the AEM boost sensors, etc., etc.  A complete list can be found on our [[externalsensorlist|Supported Aftermarket Sensors]] page.

 If you right click on the LinBoost item and select preferences,​ you'll get a dialog where you can configure the boost sensor'​s properties. ​ This will look something like the following: If you right click on the LinBoost item and select preferences,​ you'll get a dialog where you can configure the boost sensor'​s properties. ​ This will look something like the following:

 As you can see, the next step is pretty easy.  You simply punch in two voltage-to-value pairs from the sensor manufacturer'​s documentation and you're done.  ​ As you can see, the next step is pretty easy.  You simply punch in two voltage-to-value pairs from the sensor manufacturer'​s documentation and you're done.  ​

 Next, determine a Min volts and min lambda point. ​ Force a measured gasoline A/F ratio of 11.0:1 (lambda = 0.75). ​ Observe the logged RawLinWideband voltage. ​ Set Min volts to the observed value and set Min lambda to 0.75.  Finish by restoring your normal closed-loop configuration and verify that the ECMLink displayed A/F ratio values match those displayed by the wideband unit. Next, determine a Min volts and min lambda point. ​ Force a measured gasoline A/F ratio of 11.0:1 (lambda = 0.75). ​ Observe the logged RawLinWideband voltage. ​ Set Min volts to the observed value and set Min lambda to 0.75.  Finish by restoring your normal closed-loop configuration and verify that the ECMLink displayed A/F ratio values match those displayed by the wideband unit.
