DINANTRONICS Sport Tuner for BMW N20 / N26 / N55 2011-2019

DINANTRONICS Sport (D440-0010) is Dinan's plug-in boost controller for a wide range of F-chassis BMWs with the N20, N26, or N55 engine. It taps a single sensor, works with the factory DME rather than replacing it, and remaps boost, fueling, and timing. Installation and removal are meant to be quick and discreet. The module detects which engine it is sitting on and loads the matching map, so the same unit can move with you to another listed car.

A built-in Bluetooth Smart radio talks to Dinan's iOS and Android apps (Android 8.0 Oreo is not supported). From the phone you can step through Sport, Sport+, and Race, drop boost 3 psi for valet or parental control, and watch a live boost gauge similar in spirit to the iDrive sport gauges. Dinan rates maximum gains at up to 30 horsepower and 50 lb-ft on N20 engines and up to 30 horsepower and 40 lb-ft on N55 engines. Those are peak figures on the most responsive listed applications, not a promise that every car in the table will see the same number.

DINANTRONICS Sport does not carry Dinan's factory-matching vehicle warranty. The coverage on this module is a 1-year product-only warranty that does not include consequential damage or labor. It is not legal for sale or use in California on any pollution-controlled vehicle. There is no published shipping weight from our usual dimensional source for this SKU, so that row is omitted rather than guessed.

The fitment table below lists N20, N26, and N55 chassis from Dinan's 2011-2019 application title and the US dealer chart, using US model years for those engines. Turner also printed F25 xDrive28i N52 and F25 xDrive35i N54 rows; those engines are outside Dinan's N20/N26/N55 scope and are not included. F48 X1 and later B-series cars use a different Sport module.
