Stage 1 (D-TRONICS Performance Tuner ONLY) Maximum Power: 364 HP, 375 lb-ft of torque. A gain of 64 HP and 75 lb-ft of torque over stock. 

The D-TRONICS 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 was also designed to be emissions legal in 50 states (E.O. Pending). 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 Dinan® Difference

The biggest benefit of Dinan's D-TRONICS 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 possible by employing a full staff of talented engineers that are well rounded in all aspects of their job. Manipulating these signals with an adept hand all the while keeping an engine running at its best and with 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 then 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. These errors can cause the on-board diagnostics systems to set faults, but they can also cause exceedingly high catalyst temperatures and a loss of power. In addition, when power is increased, exhaust gas temperature will increase as well and this must be countered with a slightly richer air/fuel mixture. The D-TRONICS Performance Tuner uniquely has the capability to adjust target Lambda, correct short term trim as well as ignition timing errors induced by raising boost pressure. This enables Dinan® calibration engineers to optimize air/fuel mixture and ignition timing at elevated boost pressure throughout the entire gamut of engine RPM and engine load. Additionally, the ability to correct short term trim corrections (the difference between target and scheduled fuel mixture) remain within OEM specifications. This minimizes knock sensor activity, which in turn means smooth engine performance, catalyst protection and power increase, while this is also required to make the car emissions legal. Dinan engineers have worked for two years on the D-TRONICS Performance Tuner in efforts to provide BMW enthusiasts with Performance without Sacrifice. 

Unmatched Warranty

Dinan's comprehensive warranty program, introduced in 1997, provides superior warranty coverage to that which you would find elsewhere. If your vehicle is currently covered by the vehicle manufacturer's new car limited warranty, Dinan® products are warranted for the remaining term of the vehicle manufacturer's new car limited warranty. The manufacturer's new car warranty is limited to 4 years or 50,000 miles (80,000 kilometers in Canada), commencing on the date of first retail sale or the date the vehicle is first placed in-service as a demonstrator or company vehicle, whichever is earlier. Dinan's warranties are transferable when ownership of the vehicle into which the Dinan® products were originally installed is sold. BMW automobiles can now be performance-tuned without the associated concern of negatively affecting the new car warranty coverage.

Designed to be Emissions Legal

The D-TRONICS Performance Tuner was designed and built to be the only tuning box on the market that is emissions legal in all 50 states. At the moment this product is emissions legal in most states – the product is in compliance with US Federal EPA Memorandum 1A, or this product has not been found, nor is believed to be, unlawful for use under the provisions of the Clean Air Act. Currently this product is not legal for sale or use in California, and states that have adopted California emissions standards, on any pollution controlled motor vehicles. We are however in the E.O. process with the ARB and are confident that the D-TRONICS Performance Tuner will be emissions legal in all states in the near future.

Drivability   

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.

Installation    

Plug-and-Play installation in two hours or less at any of the 180+ Dinan® Dealers. While firmware is loaded directly on the ECU the model specific software will need to be downloaded into the ECU by an authorized Dinan dealer after installation. Log on to www.dinancars.com to find your nearest dealer or contact Dinan to make an appointment.

Easy To Use   

Dinan's ECU is Bluetooth® Smart meaning that you can change maps simply via a Bluetooth connection.  Just install and you are done!

Designed for the Future

The Dinan® D-TRONICS Performance Tuner was engineered with future expansion of functionality in mind. Boasting the most powerful processing power on the market the D-TRONICS Performance Tuner can handle more functions and processes than any of its contemporaries. To that end the Dinan performance tuner is capable of interfacing with the CAN and FlexRay communication systems which allow for controlling powertrain functions, among others. This means that when new functions are developed there will be no need for a new box, just a short software update at your local Dinan dealer.

Satisfaction Guaranteed

Dinan® guarantees you will be impressed by the D-TRONICS Performance Tuner and the performance it provides that we offer a 3-Day return policy. If you aren't satisfied with what the Dinan solution brings to the table within 3 days of install you can go back to your dealer for a full refund (installation labor costs still apply).
