**NOTE:** With the release of [[v3firmwarechangelog|version 3.19.139]], we have dramatically changed how AFRatioEst is configured. If you have at least version 3.19.139 inside your ECU, you can ignore this entire section because the configuration of AFRatioEst is done for your automatically. You can check to see which version is inside your ECU by reading the "Check your current firmware version" section of [[v3firmwarehowto|this page]]. | **NOTE:** With the release of [[v3firmwarechangelog|version 3.19.139]], we have dramatically changed how AFRatioEst is configured.

AFRatioEst provides an **estimated** A/F ratio based on reported airflow and commanded fuel (injector pulsewidth). This should NOT be used to performance tune your car. It should be used as a check that reported airflow and estimated fuel flow make sense. This display value depends on knowing a LOT about your setup. If you do not provide accurate information here, you will not get accurate results. Garbage in = garbage out. | AFRatioEst provides an **estimated** A/F ratio based on reported airflow and commanded fuel (injector pulsewidth). This should NOT be used to performance tune your car.
