The EVO8 MAF (which is effectively the same as a 3G Eclipse MAF) has an airflow metering capacity at least 20-30% more than the 2G DSM MAF, which is already pretty darn good. These are the values you'd use in the MAF compensation dialog box if you were to install an EVO8 MAF in place of a 2G MAF. Note for 1G guys that you will need to select “2G MAF” as your base MAF type first. The following compensation values are based on the assumption that the ECU is configured for a 2G MAF.
