| - | ====== Airflow Options ====== | ||
| - | 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 [[engineandecu101|Engine and ECU operation page]] first. | ||

| - | ===== Mitsubishi mass airflow sensors ===== | ||
| - | The "standard" options include a 1G DSM, 2G DSM, or an EVO8 (3G Eclipse) mass airflow sensor. Some things to note with these follow. | ||
| - | |||
| - | * Must be installed in front of the turbo. | ||
| - | * Generally provide very accurate airflow data and work well with our ECUs. | ||
| - | * Are insensitive to changes in engine VE and atmospheric conditions. | ||
| - | * Are usually easy to install, but that does depend on how you plan to run your piping before/after the turbo. | ||
| - | * Can provide some minimal restriction to airflow to the turbo. This can be a hot topic for debate, though. We generally feel this restriction is minimal at best and for most people should not be a major consideration. | ||
| - | * Uses both IAT and baro inputs to the ECU (preventing you from connecting other sensors to those inputs for logging). | ||
| - | * Have some very real limitations on airflow metering capacity. This is particularly problematic for the 1G DSM sensor. The 2G DSM is better and the EVO8 is really very nice. Some details on the limits can be found on our [[maffrequencylimits|MAF Data page]]. | ||
