ECUMaster Digital ECU Tuner 3 is the most popular piggyback tuning device in Europe and has now hit U.S. shores. Despite its small size, the DET3 is an extremely capable piggyback tuning device. The DET3 allows for the removal of the airflow meter on most applications, and can drive up to 4 injectors in batch fire. Ignition timing can be monitored and adjusted via 16×16 tables. The parametric output channels can be configured to control boost with the use of a boost control solenoid, nitrous activation, water or methanol injection control, etc. Launch control and map switching are also among the advanced features available to the end user. In “Fuel Implant” mode, the DET3 operates much like a standalone ECU, calculating fuel requirements based on RPM, IAT, CLT, TPS and even O2 feedback. This listing is for a DET3 with built in 2.5 or 4 bar map sensor.
