The Story:

Flash tuning meets convenience and versatility with a feature rich handheld device. That’s right – the most significant and important performance enhancement available for your turbo charged car is now deliverable from the comfort of your drivers’ seat. With multiple octane calibrations dependent on your specific needs, desires or limitations nestled in the palm of your hand you can switch to the appropriate map with the click of a few buttons and a short flash.

The main component of the DINANFLASH Handheld is the B58(M0) and 'F' Chassis B46 Dinan performance engine software loaded onto the device which is your ticket to maximum power. Not just any power however - safe, reliable power that does not sacrifice the long-term health of the engine. 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 labelled as being the smoothest, factory-like solution in the marketplace.

While the tune itself is the most noteworthy aspect of the DINANFLASH Handheld it is also much more than just an improved delivery mechanism for the masses. It is loaded with additional features that assist in monitoring, logging and troubleshooting as well. These features allow increased visibility on the inner workings of the engine/vehicle and help to ensure that the car is functioning at peak performance at all times.
