Dinan - Plus Performance Engine Software - BMW F8X M3/M4 & F87 M2C

DINAN PERFORMANCE SOFTWARE QUICK SPECS & SUMMARY:

Dinan has a long and storied past when it comes to engine tuning having introduced our first engine performance chip in the mid 80's — over 3 decades ago. From those early years with chips, followed by engine software and then to our own external control modules we have become experts in nearly every possible way to extract safe, reliable power from the factory powerplant. While we have long preferred the unheard of control and sophistication capable of being achieved from engine software, over the past 6 years that option was not one afforded to us. That changes now with the re-introduction to flash tuning for Dinan with the S55 engine. 

The first of the next generation of Dinan flash tunes, the S55 callibrations are held to the same principles of the past; performance, reliability and safety. Dinan performance engine software is so much more than just tuning up the turbo boost after all.  It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place.  Protecting your BMW while giving the most performance is the definition of "Performance Without Sacrifice". Drivetrain and engine components are analyzed for strength then the callibration is tested on the dyno and in the real world for durability and drivability.

This next generation of Dinan flash tunes does differ from the past however in that there are many different options to choose from depending on your needs or desires. Whether you want a warranted tune for 93 pump gas when under the factory warranty, an E85 performance tune for maximum performance when outside of the factory warranty, or something in between, chances are Dinan has an option for you.
