DINAN + PERFORMANCE ENGINE SOFTWARE - BMW S58 ENGINE

The S58 motor, even early in its production life, is known as an immensely capable engine delivering power well beyond its advertised levels. This is typical of most modern-day BMW M platforms. What is not typical however is the copious amounts of headroom left on the table for entities like Dinan to take advantage of. Approaching, and/or exceeding, maximum gains of 100 WHP/TQ with pump gas and no additional modifications for an inline-6 is a dream that has become a reality.

While increases in power via ECU upgrades in the marketplace can come at a cost to the engine's durability, this is typically due to improper calibrations that are simply after one goal regardless of engine health - maximum power. Dinan's calibrations are safe and reliable without sacrificing long-term reliability or performance. Dinan performance engine software is so much more than just turning 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. In most cases Dinan software engineers also implement their own additional safety precautions in order to guarantee flawless performance that may not have been needed with factory power levels/programming. Protecting your BMW, while giving the most performance, is the definition of "Performance Without Sacrifice". To do just that, drivetrain and engine components are analyzed for strength, and then the calibration is tested on the dyno and in the real world for durability and drivability. This process has been a cornerstone of Dinan software development for decades and a major reason why Dinan performance tunes are often labeled as being the smoothest, factory-like solution in the marketplace.

Dinan's ECU upgrades are offered in numerous configurations depending on your specific needs, desires or limitations. Whether you are limited to 91 pump gas, want to experience maximum performance on E85, or something in between, chances are Dinan has an option for you. At its core Dinan offers 2 base options; Stage 1 and Dinan +. The Dinan Stage 1 Performance Engine Software is designed for the S58 engine to yield maximum power (for a variety of different octanes), improve drivability, and remove the factory speed governor for unadulterated entertainment. The Dinan + variant of software offers these same features (albeit limited to 91/93 octane) but also carries the signature Dinan 4yr / 50k, factory matching new car warranty that the brand is synonymous with.

FEATURES
