D-TRONICS Performance Tuner Description



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.



State-of-the-art Hardware



The D-TRONICS 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 D-TRONICS 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.



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.




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.








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.
