Digital ECU Tuner 3 is the most popular device as a "piggy back" unit on the market. Due to its many features and cost friendly price, this product has gained a large group of satisfied customers and becoming one of the most purchased piggy back units in the UK.
 
For most applications, the DET3 allows for the removal of an airflow meter, can drive up to 4 injectors in batch fire and Ignition timing can be 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.
