Скачать или смотреть How the Throttle Derivative (DTPS) Strategy Works in GET ECUs – Transient Fuel Correction in MAYA

📌 In this technical tutorial, we explore the Throttle Derivative Strategy (DTPS)—also known as the butterfly derivative—in the context of GET ECU programming using MAYA. This strategy enables precise transient fuel correction during throttle openings and closings, based on throttle speed and RPM.

📝 You’ll learn how to:
Understand the logic behind the butterfly derivative strategy for transient phases
Set up a new layout in MAYA to monitor and edit relevant variables: matrices, vectors and scalars
Configure the acceleration matrix (J) and decay vector to control the fuel enrichment
Interpret real-time data using scope views and logger examples
Analyze derivative update rules based on three events:
1. A higher derivative replaces the previous one
2. A derivative of opposite sign takes over
3. The decay completes and the correction expires
Visualize the triangular shape of the fuel correction and how it evolves over time
Apply different DTPS configurations to Map 1 and Map 2

Unlike static fuel corrections (e.g. coolant or air temp), DTPS is temporary, precise, and self-resetting—making it essential for optimal ECU behavior during rapid load changes.
