Dinan PCU - 2021-2025 BMW M2/M3/M4 & 2020-2025 BMW X3M/X4M

Developed wholly from the ground up, the Dinan Power Control Unit (PCU) is an evolutionary step in Dinan in-line tuning modules based off over a decade of lessons learned in the category. At its core the PCU is similar to its precursors and installs in between select sensors and the ECU, adjusting these signals in order to achieve increased performance the stock programming is unable to approach. However, what sets the PCU apart is its integration into more than just the fundamental boost sensors but also additional connections -- inclusive of OBDII. The result is a more capable system that can do so much more than just increase power. Live monitoring of vehicle health via logging, customizable gauges, and code reading/clearing, among others, are now possible ensuring a seamless tuning experience even a novice can be comfortable with.

The Dinan PCU is controlled by a free Bluetooth app, available for both iOS and Android, and is home to all the potent features the device offers. Equipped with 5 different pre-set performance levels, in addition to stock, you can choose to select your desired output and enjoy more power for a true install and forget experience, or you can opt to engage in the more advanced features at your fingertips. Boost by gear customization, as an example, allows you to limit power delivery as you see fit in lower gears ensuring optimum traction and a perfect launch. Where the PCU shines however is in data acquisition and monitoring that gives insight into the vehicles overall health and makes certain your tuned vehicle is always running at peak potential.

Safety and reliability have been cornerstones of the Dinan brand for generations and not only does the Dinan PCU not hinder any factory safeguards or emissions controls but incorporates its own safeties as well. Going one step beyond our own internal protections, the PCU also grants the end user the ability to monitor up to 20 different engine parameters in real time via customizable in-app gauges for verification of worry-free operation. Those same parameters can also be logged/viewed in app (or exported to CSV) for further scrutiny if desired.

All told, the Dinan PCU delivers more power and more features with improved reliability and drivability than ever offered before. Performance without sacrifice is alive and well!
