 On this page, we're going to assume you've already run through the install procedure and have gotten a good connection established with the ECU.  If you have not, please review the [[ecmlink101install|Installation]] page first.
 ===== Verify =====
 ==== Base MAF type ====
-In the ECU Config -> MAF Comp tab, check your Base MAF type.  This should say something like "Stock", "3G/EVO8", "GM 3in", etc.  You want to make sure this matches what you actually have installed on the car.  If you have a GM MAF translator, then you'll want to select "Stock" because the translator is supposed to provide a signal to the ECU that more or less simulates a stock Mitsubishi airflow sensor.

 Once BoostEst is in the graph legend, double click it or right click on it and select BoostEst -> BoostEst preferences.  Enter your engine displacement (2.0L is the normal, stock value for our DSM motors) and your altitude then hit OK.
 ==== AFRatioEst ====
+**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]].
+=== For versions prior to 3.19.139 ===
 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.
