DINAN official website


DINAN Engineering, North America’s BMW tuner, is pleased to announce the introduction of the anxiously awaited Performance Engine Software for BMW 335i models. And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages*. No one offers better performance or backs it up with such comprehensive warranty coverage.

The Dinan Performance Engine Software safely increases turbo-boost pressure from the stock 8.8 to 13.2 psi, along with properly retuned fuel mixtures, ignition timing and full map rescaling. In fact, over 2000 engine management functions have been recalibrated, offering substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product. Some examples include:

Remapped Water Pump Speeds. In an effort to more effectively control oil and water temperatures, which have been notably excessive even at stock boost pressures, the Dinan software actually increases water pump speeds as boost pressure increases. A much larger, more efficiently ducted oil cooler has also been developed, further improving heat exchange for lower and more consistent operating temperatures, even with the added boost pressure.

Boost Pressure Control. Increased boost pressure exceeds the turbochargers’ design limitations at higher rpm, potentially shortening their lifespan. Dinan addresses this issue by tapering the boost gradually at higher engine speeds. This approach also addresses the fact that with increased boost at higher rpm the turbocharger temperatures would exceed the intercooler’s ability to cool the intake charge, resulting in a loss of power and compromising the long-term durability of the engine. The tapered boost keeps temperatures within the design limitations so as to optimize output and ensure engine reliability with the added boost pressure.

Top Speed Governor Removed. With Dinan’s software, the 335 will be capable of achieving its natural top speed as the governor has been removed.

The results of Dinan’s tuning are nothing short of breathtaking, with the added boost and related recalibration producing maximum output of 384 horsepower at 5700 rpm and 421 lb-ft torque at 4300 rpm. All of this additional power is available from Dinan’s software alone, which is easily downloaded by your Authorized Dinan Dealer in about an hour for 2007 models (2008 model year vehicles require that the ECU is removed and shipped to Dinan for installation of the software at this time).

335i Turbo ::: Oil Cooler Upgrade
High Capacity Oil Cooler for 335 Models!

It’s no secret among 335 owners that while the cars perform admirably, they tend to run a bit on the warm side. This appears to be true even with the cars equipped with the factory oil cooler; and in case you weren’t aware, not all 335s came with an oil cooler at all! For those who drive the cars in a spirited fashion on a regular basis, this issue is even more pronounced. While this is certainly a concern in stock form, it becomes even more of an issue when you consider increasing boost pressure, which in addition to added power output also generates more heat. And when you back your products with matching new car warranty coverage, including consequential damages, you tend to be a bit more concerned about the real world ramifications of increased turbo boost pressure on the car as a whole. Recognizing the significance of this issue, Dinan set out to develop a more efficient heat exchanger, ultimately in the form of a High Capacity Oil Cooler. Two complete systems have been developed, one for vehicles that weren’t equipped with a factory oil cooler and the other as an upgrade for the stock unit. Now every 335 driver has the opportunity to lower operating temperatures

The Dinan High Capacity Oil Cooler provides literally twice the volume of the stock unit, as well as 414 sq./in. of cooling tube vs. 112.5, and that’s really just the beginning. Nicely integrated inlet ducting provides greater airflow efficiencies and the ventilation of air to the fender well has also been improved with a larger outlet. The system mounts neatly in the stock location and includes lightweight convoluted PTFE hoses with polyester outer braid fitted with race-quality fittings. For cars that were not equipped with the factory oil cooler, kits are available that include all of the additional parts necessary for the installation. The results of the oil cooler upgrade are quite significant, with the temperature gauge holding steady even under high load/high boost scenarios. And for those of you who track their cars, even occasionally, the Dinan oil cooler is a must.

Specifications

Total Volume: Stock = 9.5 oz. / Dinan = 19 oz. Surface Area: Stock = 45 sq./in. / Dinan = 67.5 sq./in. Cooling Tubes: Stock = 10 / Dinan = 23 Tube Lengths: Stock = 90 in. / Dinan = 207 in. Tube Area: Stock = 112.5 sq./in. / Dinan = 414 sq./in.
