The Ecumaster Digital ECU Tuner 3 (DET3) is a piggyback engine management module that works alongside the factory ECU to fine-tune fueling and ignition without fully replacing the stock computer. It can remove the factory airflow meter from the tuning equation, drives up to 4 injectors in batch-fire mode, and adjusts ignition timing through a 16x16 map; it also supports boost control, nitrous activation, water/methanol injection management, launch control, and map switching, and includes a built-in MAP sensor (250 kPa or 400 kPa versions) with Windows-based tuning software.

Fitment: Universal piggyback tuning module suitable for a wide range of gasoline and common-rail diesel engines across most makes and models.
