With the release of ECMLink, users have the option to run any number of different mass airflow solutions. They can run a Mitsubishi MAF sensor (1G, 2G, EVO8), any one of a number of GM MAF sensors, or they can run speed density. This page outlines some of the considerations of each.

If you're not sure how airflow plays into the grand scheme of engine management, then please read the Engine and ECU operation page first.

The “standard” options include a 1G DSM, 2G DSM, or an EVO8 (3G Eclipse) mass airflow sensor. Some things to note with these follow.

• These must be installed in front of the turbo.
• They generally provide very accurate airflow data and work well with our ECUs.
• They are usually easy to install, but that does depend on how you plan to run your piping before/after the turbo.
