Dinan DINANFLASH Handheld Tuners

Dinan DINANFLASH handheld tuners deliver flash tuning along with convenience and versatility in a feature-rich handheld device. 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 handhelds is the Dinan performance engine software loaded onto the device which is your ticket to maximum power. However, not just any power--safe, reliable power that does not sacrifice the long-term health of the engine. 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 to guarantee flawless performance that may not have been needed with factory power levels/programming.

To protect your BMW, while giving the most performance, 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, making Dinan performance tunes are often labeled as being the smoothest, factory-like solution in the marketplace.

Much more than just an improved delivery mechanism for the masses, Dinan DINANFLASH handheld tuners are 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 your car is always functioning at peak performance.
