-**__RUNNING WITHOUT AN IAT SENSOR__:** You can run speed density reasonably well without an IAT sensor at all if you have to.  It is absolutely better to have one, no questions ​about it.  But if you find yourself in the situation where you simply can't get an IAT sensor installed but you need to enable speed density operation anyway, go ahead. ​ Just make SURE you go into the Direct Access tab and zero out the **SDTempWeighting** table. ​ Doing so basically tells the ECU to ignore the IAT input when running SD.+**__RUNNING WITHOUT AN IAT SENSOR__:** You can run speed density reasonably well without an IAT sensor at all if you have to.  It is absolutely better to have one, no question ​about it.  But if you find yourself in the situation where you simply can't get an IAT sensor installed but you need to enable speed density operation anyway, go ahead. ​ Just make SURE you go into the Direct Access tab and zero out the **SDTempWeighting** table. ​ Doing so basically tells the ECU to ignore the IAT input when running SD.

 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.
