DINANTRONICS Performance Tuner Stage 1 for BMW F15 X5 F16 X6 50i


Stage 1 (DINANTRONICS Performance Tuner alone) Maximum Power: 506 BHP, 547 lb-ft of torque.

The DINANTRONICS Performance Tuner is highly engineered and sophisticated 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's 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 ECU. These attributes are unique to Dinan, and together they embody the apex of performance engineering.

The Dinan Difference

The biggest benefit of the DINANTRONICS Performance Tuner is our ECU has the "capability of setting an optimum target lambda (fuel mixture) as well as correcting short term trim which is the difference between target and scheduled fuel mixture. By matching these two correctly we can reduce knock sensor activity which will make smoother performance, protect the catalyst, increase power and allow us to make it emissions legal."- Steve Dinan

The Dinan Difference is created by a full staff of talented engineers who are well-versed in manipulating these signals, all the while keeping your engine running at its best. The most reliable power is what Dinan is all about!

Well Engineered

Plug-in tuning devices all have one thing in common: they send a modified signal to the factory ECU, telling it the boost pressure is below target values. This causes the factory ECU to raise the boost pressure to what it thinks is the correct value. This modified boost pressure signal causes errors in fuel mixture and ignition timing, which can cause on-board diagnostics systems to set faults. Worse, they can also cause exceedingly high catalyst temperatures and a loss of power. In addition, when power is increased, exhaust gas temperature will increase; this must be countered with a slightly richer air/fuel mixture.

The DINANTRONICS Performance Tuner is unique in its capability to adjust target Lambda, correcting short term trim and ignition timing errors induced by raising boost pressure. This lets Dinan calibration engineers optimize air/fuel mixture and ignition timing at elevated boost throughout the gamut of engine RPM and engine load. Additionally, the ability to correct short term trim (the difference between target and scheduled fuel mixture) remains within OEM specifications. This minimizes knock sensor activity, which means smooth engine performance, catalyst protection, and power increase. This is also required to make the car emissions legal. Dinan engineers have worked for years on the DINANTRONICS Performance Tuner in order to provide BMW enthusiasts with our "Performance Without Sacrifice!"

State-of-the-Art Hardware

The DINANTRONICS Performance Tuner is engineered using the highest quality components and advanced hardware. Using OE connectors and an expandable, braided wiring sleeves ensures that all visible components look factory. More important, it guarantees long-lasting and dependable performance due to the use of heat-, moisture-, and abrasion-resistant materials and design.

The other hardware element is the Dinan ECU itself. The processing power and sophistication of its internal circuitry is exceptional, capable of delivering signals to various systems at an astonishing 4000 times per second. This immense processing power equates to a high degree of engine control, resulting in a much lower likelihood of setting a fault. Smoother running conditions and superior drivability are achieved, all of which are Dinan hallmarks.

Unmatched Warranty

Dinan's comprehensive warranty program provides superior warranty coverage to any other in the industry. If your vehicle is currently covered by your manufacturer's new car limited warranty, Dinan products are warranted for the remaining term of that new car limited warranty. Dinan's warranties are transferable when ownership of the vehicle is transferred  BMWs can now be performance-tuned without negatively affecting the new car warranty coverage!

50 State Emissions Legal

The DINANTRONICS Performance Tuner was designed and built to be the only tuning box on the market that is emissions legal in all 50 states by virtue of California Air Resources Board executive order D-176-42.


There is more to a tune than just cranking up the boost. Power needs to come on smoothly and in a predictable way to make the car as fun to drive at wide open throttle as cruising around town.  It is your BMW, but reborn with new found acceleration and speed.
