Description

The Dinan Power Control Unit (PCU) is an evolutionary step in Dinan in-line tuning modules, built on more than a decade of lessons learned in the category. At its core, the PCU is similar to its predecessors: it installs between select sensors and the ECU, adjusting signals to achieve increased performance beyond what stock programming can provide. What sets the PCU apart, however, is its integration beyond the fundamental boost sensors to include additional connections—OBD-II included. The result is a more capable system that can do far more than simply increase power. Live monitoring of vehicle health via logging, customizable gauges, and code reading/clearing (among other features) are now possible, ensuring a seamless tuning experience that even a novice can feel comfortable with.
