The DINANTRONICS™ Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negating or voiding your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It is also the only tuning device emissions legal in all 50 states. The ultimate objective of developing this piece of technology was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package.  The DINANTRONICS Performance Tuner is engineered using the best possible components and advanced hardware. The most obvious and visible component is the elaborate wiring harness. Using OE connectors and an expandable braided wiring sleeves ensures that all visible components appear as if they come straight from the factory. More importantly however it guarantees long lasting and dependable performance due to the use of high heat, moisture and abrasion resistant materials and design. The other hardware element involved is the Dinan electronic control unit (ECU) itself.  While its outward appearance may seem tame, the processing power and sophistication held within its internal circuitry is anything but. Capable of delivering signals to various systems at an astonishing 4000 times per second the DINANTRONICS Performance Tuner yields the power to control all current signals delivered to the ECU as well as those developed  in the future without a hiccup in performance or reliability.  This immense processing power equates to a high degree of engine control resulting in a much lower likelihood of setting a fault. In addition smoother running conditions and superior drivability are achieved, all of which are Dinan hallmarks.
