 In calculating fuel requirements for an engine, the amount of air (n in the above equation) is the critical piece of data we need to solve for.  To solve for that, we need to know absolute pressure, absolute temperature and volume. In calculating fuel requirements for an engine, the amount of air (n in the above equation) is the critical piece of data we need to solve for.  To solve for that, we need to know absolute pressure, absolute temperature and volume.

-Pressure and temperature are easy enough to measure in our application using off the shelf sensors like the GM IAT for temperature and the GM 3-bar sensor for pressure. ​ Other pressure sensor options are listed on our [[externalsensorlist|Aftermarket Sensor List]]. ​ These include the GM 3.3-bar, AEM 3.5-bar and AEM 5-bar sensors. ​ Other sensors listed on that page can be logged, but are not suitable for SD operation because they do not provide a reliable **absolute** pressure reading.+Pressure and temperature are easy enough to measure in our application using off the shelf sensors like the GM IAT for temperature and the [[http://​www.ecmtuning.com/​product_info.php?​cPath=28&​products_id=47|4-bar sensor]] we provide on our site for pressure. ​ Other pressure sensor options are listed on our [[externalsensorlist|Aftermarket Sensor List]]. ​ These include the GM 3-bar, ​GM 3.3-bar, AEM 3.5-bar and AEM 5-bar sensors. ​ Other sensors listed on that page can be logged, but are not suitable for SD operation because they do not provide a reliable **absolute** pressure reading.  We also offer a [[http://​www.ecmtuning.com/​product_info.php?​cPath=28&​products_id=50|Speed Density bundle]] on our site as well, which includes the standard 4-bar pressure sensor and the IAT sensor along with necessary pigtails and bung.
  
 For air temperature,​ the only supported sensor is the GM IAT sensor (AEM IAT sensor is actually the same thing). ​ You can get part number information off the [[externalsensorlist|Aftermarket Sensor List]] page.  ​ For air temperature,​ the only supported sensor is the GM IAT sensor (AEM IAT sensor is actually the same thing). ​ You can get part number information off the [[externalsensorlist|Aftermarket Sensor List]] page.  ​
