![]() ![]() SD mode is a full-time SD operation where the ECU uses the SD-based airflow calculation. This mode allows you to get a starting VE table up and running before actually running SD or allows you to tune MAF sensor calibration as you would with the factory ECU. MAF mode mimics the factory logic in which airflow is determined by the MAF sensor and the MAF Calibration table. Tuners can select from three different real-time tunable modes of operation.SD airflow compensations for engine coolant temp (ECT) and barometric pressure are also available. This table can be tweaked according to manifold pressure, allowing for changes that may be needed based on IAT sensor placement. A real-time tunable intake air temperature (IAT) compensation table allows the tuner to tweak the SD charge temperature correction.Because the VE table units represent actual VE, properly calibrated SD tunes can be used to compare VE across different cars with different mods, even if the SD airflow is drastically different. Tuning SD is achieved through manipulating a real-time tunable volumetric efficiency (VE) table.This keeps much of the existing factory logic in place, allowing for the safe and reliable operation of the factory ECU while reducing the learning curve associated with tuning SD. SD works by calculating a new SD-based airflow to replace the factory MAF sensor-based airflow when SD is active.The following is a list of the key features of COBB Speed Density (SD): ![]() RPM = Revolutions Per Minute (referring to engine speed).EJ 2.0L = Subaru's port-injected EJ 2.0L motor (02-05 WRX).DIT Gen2 = A second generation CCF ECU for DIT vehicle types that adds additional features (including SD) over the Gen1 DIT CCF type.DIT = Subaru's "Direct Injection Turbo" motor (14-18 FXT, 15+ WRX).CCF = Cobb Custom Features (generally referring to the CCF ECU type which contains custom features not otherwise available on the factory ECU).Or SD can be used on the low end to improve idle/cruise characteristics when a big MAF is used, while still retaining MAF sensor operation on the high end. In a special hybrid mode, SD can be used on the high end to overcome a maxed out MAF sensor, while still retaining MAF sensor operation on the low end.SD allows for the MAF sensor to be removed, eliminating a potential restriction in the intake tract and allowing for more freedom in intake piping design.SD can eliminate the noisy airflow calculation sometimes seen when using a MAF sensor-based configuration with heavily modified cars.UsesĬOBB Speed Density (SD) has a number of potential uses that can improve the tuning capability for particular set-ups: It is highly customizable and features such as real-time tuning aid in a speedy and efficient tuning process. The COBB Speed Density feature is a powerful yet easy-to-use solution that integrates Speed Density tuning into the Subaru engine control unit (ECU) and can be used to entirely replace or work in conjunction with the existing factory mass airflow (MAF) sensor. If that is not enough then we offer a full insurance backed mechanical breakdown warranty underwritten by AVIVA and a full 14 day money back guarantee.Note: This guide covers COBB Speed Density for EJ 2.0L, EJ 2.5L and DIT Subarus.
