-Although we can't possibly document all the different combinations of MAP sensors going to all the different ECU inputs, we will at least document the "​typical"​ case of installing our GM-style Omni power 4-bar sensor to the car's baro input. ​ If you have our [[http://​www.ecmtuning.com/​product_info.php?​cPath=26&​products_id=52|SD cable]] then, of course, you can just plug it straight up; no wiring or soldering required. ​ But if you do not, then you'll have the green pigtail shown in [[http://​www.ecmtuning.com/​images/​gmbundle.jpg|this image]].+Although we can't possibly document all the different combinations of MAP sensors going to all the different ECU inputs, we will at least document the "​typical"​ case of installing our GM-style Omni power 4-bar sensor to the car's baro input. ​ If you have our [[https://​www.ecmtuning.com/​product_info.php?​cPath=26&​products_id=52|SD cable]] then, of course, you can just plug it straight up; no wiring or soldering required. ​ But if you do not, then you'll have the green pigtail shown in [[https://​www.ecmtuning.com/​images/​gmbundle.jpg|this image]].

 Because you can connect your MAP sensor to any number of ECU inputs, you have to tell the ECU where it can find this sensor in order to use it for SD operation. ​ You do this on the ECU Inputs tab in the "Pin Assignments for ECMLink Functions (ECU-side)"​ area. Because you can connect your MAP sensor to any number of ECU inputs, you have to tell the ECU where it can find this sensor in order to use it for SD operation. ​ You do this on the ECU Inputs tab in the "Pin Assignments for ECMLink Functions (ECU-side)"​ area.

 The final step is to set the engine displacement. ​ On the Speed Density tab, there'​s a text box where you need to enter your engine displacement. ​ The ECU uses this information to correctly calculate airflow. ​ More information on this process is outlined in the [[sd101|SD101 page]]. The final step is to set the engine displacement. ​ On the Speed Density tab, there'​s a text box where you need to enter your engine displacement. ​ The ECU uses this information to correctly calculate airflow. ​ More information on this process is outlined in the [[sd101|SD101 page]].

 Mass airflow sensors used by the DSM ECU tend to require some "​smoothing"​ or "​averaging"​ inside the ECU of their output signal. ​ This type of averaging actually delays the signal used by the ECU (since it's averaged out, a real change in airflow takes a little longer to register inside the ECU).  Fortunately,​ mass airflow sensors respond very quickly to changes in airflow rate, so this delay isn't a problem. Mass airflow sensors used by the DSM ECU tend to require some "​smoothing"​ or "​averaging"​ inside the ECU of their output signal. ​ This type of averaging actually delays the signal used by the ECU (since it's averaged out, a real change in airflow takes a little longer to register inside the ECU).  Fortunately,​ mass airflow sensors respond very quickly to changes in airflow rate, so this delay isn't a problem.
